-# Bento & PostgreSQL
-
-- Bento can also use SQL databases for input/output
-
-- We're going to demonstrate that by writing to a PostgreSQL database
-
-- That database will be deployed with the Cloud Native PostGres operator
-
-  (https://cloudnative-pg.io/)
-
----
-
-## CNPG in a nutshell
-
-- Free, open source
-
-- Originally created by [EDB] (EnterpriseDB, well-known PgSQL experts)
-
-- Non-exhaustive list of features:
-
-  - provisioning of Postgres servers, replicas, bouncers
-
-  - automatic failover
-
-  - backups (full backups and WAL shipping)
-
-  - provisioning from scratch, from backups, PITR
-
-  - manual and automated switchover (e.g. for node maintenance)
-
-  - and many more!
-
-[EDB]: https://www.enterprisedb.com/workload/kubernetes
-
----
-
-## What we're going to do
-
-1. Install CNPG.
-
-2. Provision a Postgres cluster.
-
-3. Configure Bento to write to that cluster.
-
-4. Set up a Grafana dashboard to see the data.
-
----
-
-## 1️⃣ Installing CNPG
-
-Many options available, see the [documentation][cnpg-install]:
-
-- raw YAML manifests
-
-- kubectl CNPG plugin (`kubectl cnpg install generate`)
-
-- Helm chart
-
-- OLM
-
-[cnpg-install]: https://cloudnative-pg.io/documentation/1.24/installation_upgrade/
-
----
-
-## 2️⃣ Provisioning a Postgres cluster
-
-Minimal manifest:
-
-```yaml
-apiVersion: postgresql.cnpg.io/v1
-kind: Cluster
-metadata:
-  name: db
-spec:
-  storage:
-    size: 1Gi
-```
-
----
-
-class: extra-details
-
-## For production...
-
-We might also add:
-
-- `spec.monitoring.enablePodMonitor: true`
-
-- `spec.instances: 2`
-
-- `resources.{requests,limits}.{cpu,memory}`
-
-- `walStorage.size`
-
-- `backup`
-
-- `postgresql.parameters`
-
-See [this manifest][cluster-maximal] for a detailed example.
-
-[cluster-maximal]: https://github.com/jpetazzo/pozok/blob/main/cluster-maximal.yaml
-
----
-
-## 3️⃣ Configuring Bento to write to SQL
-
-- We'll use the [`sql_insert`][sql-insert] output
-
-- If our cluster is named `mydb`, there will be a Secret `mydb-app`
-
-- This Secret will contain a `uri` field
-
-- That field can be used as the `dns` in the Bento configuration
-
-- We will also need to create the table that we want to use
-
-  (see next slide for instructions)
-
-[sql-insert]: https://warpstreamlabs.github.io/bento/docs/components/outputs/sql_insert
-
----
-
-## Creating a table
-
-- If we just want to store the city name and its population:
-  ```sql
-      CREATE TABLE IF NOT EXISTS cities (
-        city varchar(100) NOT NULL,
-        population integer
-      );
-  ```
-
-- This statement can be executed:
-
-  - manually, by getting a `psql` shell with `kubectl cnpg psql mydb app`
-
-  - automatically, with Bento's `init_statatement`
-
----
-
-## 4️⃣ Viewing the table in Grafana
-
-- In Grafana, in the home menu on the lift, click "connections"
-
-- Add a PostgreSQL data source
-
-- Enter the host:port, database, user, password
-
-- Then add a visualization using that data source
-
-  (it should be relatively self-explanatory!)
-
----
-
-class: extra-details
-
-## Automating it all
-
-- Expose PostgreSQL credentials through environment variables
-
-  (in the Bento container)
-
-- Use the `${...}` syntax in Bento to use these environment variables
-
-- Export the Grafana dashboard to a JSON file
-
-- Store the JSON file in a ConfigMap, with label `grafana_dashboard=1`
-
-- Create that ConfigMap in the namespace where Grafana is running
-
-- Similarly, data sources (like the Redis and the PostgreSQL one) can be defined in YAML
-
-- And that YAML can be put in a ConfigMap with label `grafana_datasource=1`

-# Autoscaling with KEDA
-
-- Cluster autoscaling = automatically add nodes *when needed*
-
-- *When needed* = when Pods are `Pending`
-
-- How do these pods get created?
-
-- When the Ollama Deployment is scaled up
-
-  - ... manually (e.g. `kubectl scale`)
-
-  - ... automatically (that's what we want to investigate now!)
-
----
-
-## Ways to implement autoscaling
-
-- Custom code
-
-  (e.g. crontab checking some value every few minutes and scaling accordingly)
-
-- Kubernetes Horizontal Pod Autoscaler v1
-
-  (aka `kubectl autoscale`)
-
-- Kubernetes Horizontal Pod Autoscaler v2 with custom metrics
-
-  (e.g. with Prometheus Adapter)
-
-- Kubernetes Horizontal Pod Autoscaler v2 with external metrics
-
-  (e.g. with KEDA)
-
----
-
-## Custom code
-
-- No, we're not going to do that!
-
-- But this would be an interesting exercise in RBAC
-
-  (setting minimal amount of permissions for the pod running our custom code)
-
----
-
-## HPAv1
-
-Pros: very straightforward
-
-Cons: can only scale on CPU utilization
-
-How it works:
-
-- periodically measures average CPU *utilization* across pods
-
-- if utilization is above/below a target (default: 80%), scale up/down
-
----
-
-## HPAv1 in practice
-
-- Create the autoscaling policy:
-  ```bash
-  kubectl autoscale deployment ollama --max=1000
-  ```
-  (The `--max` is required; it's a safety limit.)
-
-- Check it:
-  ```bash
-  kubectl describe hpa
-  ```
-
-- Send traffic, wait a bit: pods should be created automatically
-
----
-
-## HPAv2 custom vs external
-
-- Custom metrics = arbitrary metrics attached to Kubernetes objects
-
-- External metrics = arbitrary metrics not related to Kubernetes objects
-
---
-
-🤔
-
----
-
-## HPAv2 custom metrics
-
-- Examples:
-
-  - on Pods: CPU, RAM, network traffic...
-
-  - on Ingress: requests per second, HTTP status codes, request duration...
-
-  - on some worker Deployment: number of tasks processed, task duration...
-
-- Requires an *adapter* to:
-
-  - expose the metrics through the Kubernetes *aggregation layer*
-
-  - map the actual metrics source to Kubernetes objects
-
-Example: the [Prometheus adapter][prometheus-adapter]
-
-[prometheus-adapter]: https://github.com/kubernetes-sigs/prometheus-adapter
-
----
-
-## HPAv2 custom metrics in practice
-
-- We're not going to cover this here
-
-  (too complex / not enough time!)
-
-- If you want more details, check [my other course material][hpav2slides]
-
-[hpav2slides]: https://2024-10-enix.container.training/4.yml.html#toc-scaling-with-custom-metrics
-
----
-
-## HPAv2 external metrics
-
-- Examples:
-
-  - arbitrary Prometheus query
-
-  - arbitrary SQL query
-
-  - number of messages in a queue
-
-  - and [many, many more][keda-scalers]
-
-- Also requires an extra components to expose the metrics
-
-Example: [KEDA (https://keda.sh/)](https://keda.sh)
-
-[keda-scalers]: https://keda.sh/docs/latest/scalers/
-
----
-
-## HPAv2 external metrics in practice
-
-- We're going to install KEDA
-
-- And set it up to autoscale depending on the number of messages in Redis
-

-## Installing KEDA
-
-Multiple options (details in the [documentation][keda-deploy]):
-
-- YAML
-
-- Operator Hub
-
-- Helm chart 💡

-## Scaling according to Redis
-
-- We need to create a KEDA Scaler
-
-- This is done with a "ScaledObject" manifest
-
-- [Here is the documentation][keda-redis-lists] for the Redis Lists Scaler
-
-- Let's write that manifest!

-      address: redis.`default`.svc:6379
-      listName: cities
-      listLength: "10"
-```
-
----
-
-## Notes
-
-- We need to update the `address` field with our namespace
-
-  (unless we are running in the `default` namespace)
-
-- Alternative: use `addressFromEnv` and set an env var in the Ollama pods
-
-- `listLength` gives the target ratio of `messages / replicas`
-
-- In our example, KEDA will scale the Deployment to `messages / 100`
-
-  (rounded up!)
-
----
-
-## Trying it out
-
-- Apply the ScaledObject manifest
-
-- Start a Bento pipeline loading e.g. 100-1000 cities in Redis
-
-  (100 on smaller clusters / slower CPUs, 1000 on bigger / faster ones)
-
-- Check pod and nod resource usage
-
-- What do we see?
-
---
-
-🤩 The Deployment scaled up automatically!
-
---
-
-🤔 But Pod resource usage remains very low (A few busy pods, many idle)
-
---
-
-💡 Bento doesn't submit enough requests in parallel!
-
----
-
-## Improving throughput
-
-We're going to review multiple techniques:
-
-1. Increase parallelism inside the Bento pipeline.
-
-2. Run multiple Bento consumers.
-
-3. Couple consumers and processors more tightly.
-
----
-
-## 1️⃣ Increase pipeline parallelism
-
-- Set `parallel` to `true` in the `http` processor
-
-- Wrap the input around a `batched` input
-
-  (otherwise, we don't have enough messages in flight)
-
-- Increase `http` timeout significantly (e.g. to 5 minutes)
-
----
-
-## Results
-
-🎉 More messages flow through the pipeline
-
-🎉 Many requests happen in parallel
-
-🤔 Average Pod and Node CPU utilization is higher, but not maxed out
-
-🤔 HTTP queue size (measured with HAProxy metrics) is relatively high
-
-🤔 Latency is higher too
-
-Why?
-
----
-
-## Too many requests in parallel
-
-- Ealier, we didn't have enough...
-
-- ...Now, we have too much!
-
-- However, for a very big request queue, it still wouldn't be enough
-
-💡 We currently have a fixed parallelism. We need to make it dynamic!
-
----
-
-## 2️⃣ Run multiple Bento consumers
-
-- Restore the original Bento configuration
-
-  (flip `parallel` back to `false`; remove the `batched` input)
-
-- Run Bento in a Deployment
-
-  (e.g. with the [Bento Helm chart][bento-helm-chart])
-
-- Autoscale that Deployment like we autoscaled the Ollama Deployment
-
-[bento-helm-chart]: https://github.com/warpstreamlabs/bento-helm-chart
-
----
-
-## Results
-
-🤔🤔🤔 Pretty much the same as before!
-
-(High throughput, high utilization but not maxed out, high latency...)
-
---
-
-🤔🤔🤔 Why?
-
----
-
-## Unbalanced load balancing
-
-- All our requests go through the `ollama` Service
-
-- We're still using the default Kubernetes service proxy!
-
-- It doesn't spread the requests properly across all the backends
-
----
-
-## 3️⃣ Couple consumers and processors
-
-What if:
-
---
-
-instead of sending requests to a load balancer,
-
---
-
-each queue consumer had its own Ollama instance?
-
----
-

-
----
-
-## 🏗️ Let's build something!
-
-- Let's implement that architecture!
-
-- See next slides for hints / getting started
-
----
-
-## Hints
-
-We need to:
-
-- Update the Bento consumer configuration to talk to localhost
-
-- Store that configuration in a ConfigMap
-
-- Add a Bento container to the Ollama Deployment
-
-- Profit!
-
----
-
-## Results
-
-🎉 Node and Pod utilization is maximized
-
-🎉 HTTP queue size is bounded
-
-🎉 Deployment autoscales up and down
-
----
-
-## ⚠️ Scaling down
-
-- Eventually, there are less messages in the queue
-
-- The HPA scales down the Ollama Deployment
-
-- This terminates some Ollama Pods
-
-🤔 What happens if these Pods were processing requests?
-
---
-
-- The requests might be lost!
-
----
-
-## Avoiding lost messages
-
-Option 1:
-
-- cleanly shutdown the consumer
-
-- make sure that Ollama can complete in-flight requests
-
-  (by extending its grace period)
-
-- find a way to terminate Ollama when no more requests are in flight
-
-Option 2:
-  
-- use *message acknowledgement*

-
-## Tiny bit of history
-
-- Original project: Benthos
-
-- May 30, 2024: [Redpanda acquires Benthos][redpanda-acquires-benthos]
-
-  - Benthos is now Redpanda Connect
-
-  - some parts have been relicensed as commercial products
-
-- May 31, 2024: [Warpstream forks Benthos][warpstream-forks-benthos]
-
-  - that fork is named "Bento"
-
-  - it's fully open source
-
-- We're going to use Bento here, but Redpanda Connect should work fine too!
-
----
-
-## Bento concepts
-
-- Message stream processor
-
-- Each pipeline is configured by a YAML configuration that defines:
-
-  - input (where do we get the messages?)
-
-  - pipeline (optional: how do we transform the messages?)
-
-  - output (where do we put the messages afterwards?)
-
-- Once Bento is started, it runs the pipelines forever
-
-  (except for pipelines that have a logical end, e.g. reading from a file)
-
-- Embedded language (Bloblang) to manipulate/transform messages
-
----
-
-## Messages
-
-- Typically JSON objects
-
-  (but raw strings are also possible)
-
-- Nesting, arrays, etc. are OK
-
----
-
-## Getting started with Bento
-
-We're going to:
-
-1. Import a bunch of cities from a CSV file into a Redis queue.
-
-2. Read back these cities using a web server.
-
-3. Use an "enrichment workflow" to query our LLM for each city.
-
----
-
-## 1️⃣ Importing cities
-
-Let's break down the work:
-
-- download the data set
-
-- create the Bento configuration
-
-- deploy Redis
-
-- start Bento
-
----
-
-## Downloading the data set
-
-- Example database:
-
-  https://www.kaggle.com/datasets/juanmah/world-cities
-
-- Let's download and uncompress the data set:
-  ```bash
-  curl -fsSL https://www.kaggle.com/api/v1/datasets/download/juanmah/world-cities |
-    funzip > cities.csv
-  ```
-
-  (Ignore the "length error", it's harmless!)
-
-- Check the structure of the data set:
-  ```bash
-  head cities.csv
-  ```
-
----
-
-## Creating the Bento configuration
-
-- We need to find which `input` and `output` to use
-
-- Check the list with `bento list` or the [documentation][bento-inputs]
-
-- Then run `bento create INPUTNAME/PIPELINENAME/OUTPUTNAME`
-
-- Generate a configuration file:
-  ```bash
-  bento create csv//redis_list > csv2redis.yaml
-  ```
-
-- Edit that configuration file; look for the `(required)` parameters
-
-  (Everything else can go away!)
-
----
-
-## Resulting configuration
-
-If we trim all the default values, here is the result:
-
-```yaml
-input:
-  csv:
-    paths: ["cities.csv"]
-output:
-  redis_list:
-    url: redis://redis:6379 # No default (required)
-    key: cities
-```
-
-We'll call that value `csv2redis.yaml`.
-
----
-
-## Deploying Redis
-
-- Create a Deployment:
-  ```bash
-  kubectl create deployment redis --image redis
-  ```
-
-- Expose it:
-  ```bash
-  kubectl expose deployment redis --port 6379
-  ```
-
----
-
-## Starting Bento
-
-Option 1: run it manually in a pod, to see what's going on.
-
-```bash
-bento --config csv2redis.yaml
-```
-
-Option 2: run it with e.g. the Bento Helm chart.
-
-*We're not going to do that yet, since this particular pipeline has a logical end.*
-
-*(The Helm chart is best suited to pipelines that run forever.)*
-
----
-
-## Expected output
-
-.small[
-```
-INFO Running main config from specified file       @service=bento bento_version="" path=csv2redis.yaml
-INFO Launching a Bento instance, use CTRL+C to close  @service=bento
-INFO Listening for HTTP requests at: http://0.0.0.0:4195  @service=bento
-INFO Input type csv is now active                  @service=bento label="" path=root.input
-INFO Output type redis_list is now active          @service=bento label="" path=root.output
-INFO Pipeline has terminated. Shutting down the service  @service=bento
-```
-]
-
-The pipeline should complete in just a few seconds.
-
----
-
-## Checking what's in Redis
-
-- Connect to our Redis instance:
-  ```bash
-  redis-cli -h redis
-  ```
-
-- List keys:
-  ```redis
-  KEYS *
-  ```
-
-- Check that the `cities` list has approx. 47000 elements:
-  ```redis
-  LLEN cities
-  ```
-
-- Get the first element of the list:
-  ```redis
-  LINDEX cities 0
-  ```
-
----
-
-## Fun with Bloblang
-
-- Let's add a filter to keep only cities with a population above 10,000,000
-
-- Add the following block to the Bento configuration:
-
-```yaml
-pipeline:
-  processors:
-    - switch:
-        - check: this.population == ""
-          processors:
-            - mapping: root = deleted()
-        - check: this.population.int64() < 10000000
-          processors:
-            - mapping: root = deleted()
-```
-
-(See the [docs][bento-switch] for details about the `switch` processor.)
-
----
-
-## Testing our processor
-
-- First, delete the existing `cities` list:
-  ```bash
-  redis-cli -h redis DEL cities
-  ```
-
-- Then, run the Bento pipeline again:
-  ```bash
-  bento --config csv2redis.yaml
-  ```
-  (It should complain about a few cities where the population has a decimal point.)
-
-- Check how many cities were loaded:
-  ```bash
-  redis-cli -h redis LLEN cities
-  ```
-  (There should be 47.)
-
----
-
-## 2️⃣ Consume the queue over HTTP
-
-- We want to "get the next city" in the queue with a simple `curl`
-
-- Our input will be `redis_list`
-
-- Our output will be `http_server`
-
----
-
-## Generate the Bento configuration
-
-Option 1: `bento create redis_list//http_server`
-
-Option 2: [read the docs][output-http-server]
-
----
-
-## 🙋 Choose your own adventure
-
-Do you want to try to write that configuration?
-
-Or shall we see it right away?
-
---
-
-⚠️ Spoilers on next slide!
-
----
-
-## `redis2http.yaml`
-
-```yaml
-input:
-  redis_list:
-    url: redis://redis:`6379`
-    key: cities
-output:
-  http_server:
-    path: /nextcity
-```
-
-This will set up an HTTP route to fetch *one* city.
-
-It's also possible to batch, stream...
-
-⚠️ As of November 2024, `bento create` uses port 6397 instead of 6379 for Redis!
-
----
-
-## Trying it out
-
-- Run Bento with this configuration:
-  ```bash
-  bento --config redis2http.yaml &
-  ```
-
-- Retrieve one city:
-  ```bash
-  curl http://localhost:4195/nextcity
-  ```
-
-- Check what happens after we retrive *all* the cities!
-
----
-
-## 3️⃣ Query our LLM for each city
-
-- We want to ask our LLM who's the mayor of each of these cities
-
-- We'll use a prompt that will usually ensure a short answer
-
-  (so that it's faster; we don't want to wait 30 seconds per city!)
-
-- We'll test the prompt with the Ollama CLI
-
-- Then we'll craft a proper HTTP API query
-
-- Finally, we'll configure an [enrichment workflow][enrichment] in Bento
-
----
-
-## Test our prompt
-
-Assuming that our earlier Ollama Deployment is still running:
-
-```bash
-kubectl exec deployment/ollama -- \
-ollama run qwen2:1.5b "
-Who is the mayor of San Francisco?
-Just give the name by itself on a single line.
-If you don't know, don't say anything.
-"
-```
-
----
-
-## Turn the prompt into an HTTP API query
-
-Note: to install `http` in an Alpine container, run `apk add httpie`.
-
-```bash
-http http://ollama.default:11434/api/generate \
-model=qwen2:1.5b stream:=false prompt="
-Who is the mayor of Paris?
-Just give the name by itself on a single line.
-If you don't know, don't say anything.
-"
-```
-
-We get a JSON payload, and we want to use the `response` field.
-
----
-
-## Configure an enrichment workflow
-
-The [Bento documentation][enrichment] is really good!
-
-We need to set up:
-
-- a `branch` processor
-
-- a `request_map` to transform the city into an Ollama request
-
-- an `http` processor to submit the request to Ollama
-
-- a `result_map` to transform the Ollama response
-

-# Bento & RabbitMQ
-
-- In some of the previous runs, messages were dropped
-
-  (we start with 1000 messages in `cities` and have e.g. 955 in `mayors`)
-
-- This is caused by various errors during processing
-
-  (e.g. too many timeouts; Bento being shutdown halfway through...)
-
-- ...And by the fact that we are using a Redis queue
-
-  (which doesn't offer delivery guarantees or acknowledgements)
-
-- Can we get something better?
-
----
-
-## The problem
-
-- Some inputs (like `redis_list`) don't support *acknowledgements*
-
-- When a message is pulled from the queue, it is deleted immediately
-
-- If the message is lost for any reason, it is lost permanently
-
----
-
-## The solution
-
-- Some inputs (like `amqp_0_9`) support acknowledgements
-
-- When a message is pulled from the queue:
-
-  - it is not visible anymore to other consumers
-
-  - it needs to be explicitly acknowledged
-
-- The acknowledgement is done by Bento when the message reaches the output
-
-- The acknowledgement deletes the message
-
-- No acknowledgement after a while? Consumer crashes/disconnects?
-
-  Message gets requeued automatically!
-
----
-
-## `amqp_0_9`
-
-- Protocol used by RabbitMQ
-
-- Very simplified behavior:
-
-  - messages are published to an [*exchange*][amqp-exchanges]
-
-  - messages have a *routing key*
-
-  - the exchange routes the message to one (or zero or more) queues
-    </br>(possibly using the routing key or message headers to decide which queue(s))
-
-  - [*consumers*][amqp-consumers] subscribe to queues to receive messages
-
-[amqp-exchanges]: https://www.rabbitmq.com/tutorials/amqp-concepts#exchanges
-[amqp-consumers]: https://www.rabbitmq.com/tutorials/amqp-concepts#consumers
-
----
-
-## Using the default exchange
-
-- There is a default exchange (called `""` - empty string)
-
-- The routing key indicates the name of the queue to deliver to
-
-- The queue needs to exist (we need to create it beforehand)
-
----
-
-class: extra-details
-
-## Defining custom exchanges
-
-- Create an exchange
-
-  - exchange types: direct, fanout, topic, headers
-
-  - durability: persisted to disk to survive server restart or not?
-
-- Create a binding
-
-  - which exchange?
-
-  - which routing key? (for direct exchanges)
-
-  - which queue?
-
----
-
-## RabbitMQ on Kubernetes
-
-- RabbitMQ can be deployed on Kubernetes:
-
-  - directly (creating e.g. a StatefulSet)
-
-  - with the RabbitMQ operator
-
-- We're going to do the latter!
-
-- The operator includes the "topology operator"
-
-  (to configure queues, exchanges, and bindings through custom resources)
-
----
-
-## Installing the RabbitMQ operator
-
-- Let's install it with this Helm chart:
-
-  ```bash

-## Deploying a simple RabbitMQ cluster
-
-- Let's use the YAML manifests in that directory:
-
-  https://github.com/jpetazzo/beyond-load-balancers/tree/main/rabbitmq
-
-- This creates:
-
-  - a `RabbitmqCluster` called `mq`
-
-  - a `Secret` called `mq-default-user` containing access credentials
-
-  - a durable `Queue` named `q1` 
-
-(We can ignore the `Exchange` and the `Binding`, we won't use them.)
-
----
-
-## 🏗️ Let's build something!
-
-Let's replace the `cities` Redis list with our RabbitMQ queue.
-
-(See next slide for steps and hints!)
-
----
-
-## Steps
-
-1. Edit the Bento configuration for our "CSV importer".
-
-   (replace the `redis_list` output with `amqp_0_9`)
-
-2. Run that pipeline and confirm that messages show up in RabbitMQ.
-
-3. Edit the Bento configuration for the Ollama consumer.
-
-   (replace the `redis_list` input with `amqp_0_9`)
-
-4. Trigger a scale up of the Ollama consumer.
-
-5. Update the KEDA Scaler to use RabbitMQ instead of Redis.
-
----
-
-## 1️⃣ Sending messages to RabbitMQ
-
-- Edit our Bento configuration (the one feeding the CSV file to Redis)
-
-- We want the following `output` section:
-  ```yaml
-    output:
-      amqp_0_9:
-        exchange: ""
-        key: q1
-        mandatory: true
-        urls:
-         - "${AMQP_URL}"
-  ```
-
-- Then export the AMQP_URL environment variable using `connection_string` from Secret `mq-default-user`
-
-💡 Yes, we can directly use environment variables in Bento configuration!
-
----
-
-## 2️⃣ Testing our AMQP output
-
-- Run the Bento pipeline
-
-- To check that our messages made it:
-  ```bash
-  kubectl exec mq-server-0 -- rabbitmqctl list_queues
-  ```
-
-- We can also use Prometheus metrics, e.g. `rabbitmq_queue_messages`
-
----
-
-## 3️⃣ Receiving messages from RabbitMQ
-
-- Edit our other Bento configuration (the one in the Ollama consumer Pod)
-
-- We want the following `input` section:
-  ```yaml
-    input:
-      amqp_0_9:
-        urls:
-          - `amqp://...:5672/`
-        queue: q1
-  ```
-
----
-
-## 4️⃣ Triggering Ollama scale up
-
-- If the autoscaler is configured to scale to zero, disable it
-
-  (easiest solution: delete the ScaledObject)
-
-- Then manually scale the Deployment to e.g. 4 Pods
-
-- Check that messages are processed and show up in the output
- 
-  (it should still be a Redis list at this point)
-
----
-
-## 5️⃣ Autoscaling on RabbitMQ
-
-- We need to update our ScaledObject
-
-- Check the [RabbitMQ Queue Scaler][keda-rabbitmq]
-
-- Multiple ways to pass the AMQP URL:
-
-  - hardcode it (easier solution for testing!)
-
-  - use `...fromEnv` and set environment variables in target pod
-
-  - create and use a TriggerAuthentication
-
-💡 Since we have the AMQP URL in a Secret, TriggerAuthentication works great!

-
-- We want something that is *idempotent*
-
-  = running it 1, 2, 3 times, should only install the stack once
-
-- We want something that handles udpates
-
-  = modifying / reconfiguring without restarting from scratch

-- We want something that can handle *partial removals*
-
-  = ability to remove one element without affecting the rest

-
-- Kustomizations
-
-- Directories with raw YAML manifests
-
----
-
-## How `helmfile` works
-
-- Everything is defined in a main `helmfile.yaml`
-
-- That file defines:
-
-  - `repositories` (remote Helm repositories)
-
-  - `releases` (things to install: Charts, YAML...)
-
-  - `environments` (optional: to specialize prod vs staging vs ...)
-
-- Helm-style values file can be loaded in `enviroments`
-
-- These values can then be used in the rest of the Helmfile
-
-- Examples: [install essentials on a cluster][helmfile-ex-1], [run a Bento stack][helmfile-ex-2]

----
-
-## `helmfile` commands
-
-- `helmfile init` (optional; downloads plugins if needed)
-
-- `helmfile apply` (updates all releases that have changed)
-
-- `helmfile sync` (updates all releases even if they haven't changed)
-
-- `helmfile destroy` (guess!)
-
----
-
-## Helmfile tips
-
-As seen in [this example](https://github.com/jpetazzo/beyond-load-balancers/blob/main/bento/helmfile.yaml#L21):
-
-- variables can be used to simplify the file
-
-- configuration values and secrets can be loaded from external sources
-
-  (Kubernetes Secrets, Vault... See [vals] for details)
-
-- current namespace isn't exposed by default
-
-- there's often more than one way to do it!
-
-  (this particular section could be improved by using Bento `${...}`)

-## 🏗️ Let's build something!
-
-- Write a helmfile (or two) to set up today's entire stack on a brand new cluster!

-
-  - one helmfile for singleton, cluster components
-    <br/>
-    (All our operators: Prometheus, Grafana, KEDA, CNPG, RabbitMQ Operator)
-
-  - one helmfile for the application stack

-## What we will / won't cover
-
-- Kubernetes provides low-level building blocks (pods, deployments, services...)
-
-- There are many high-level frameworks out there for serverless, AI...:
-
-  [Knative](https://knative.dev/docs/),
-  [KubeAI](https://www.kubeai.org/),
-  [Kueue](https://kueue.sigs.k8s.io/)...
-
-- We're going to sit somewhere in the middle:
-
-  reimplement some of the features of these high-level frameworks, in a flexible way
-
-- This workshop will (hopefully!) give you a better eye to evaluate these frameworks, too
-
-- We won't showcase GPUs today for budget reasons
-
-  (giving everyone a few GPU nodes would be prohibitive, sorry!)
-
----
-
-## A word about our demo app
-
-- We'll use Ollama with a relatively small LLM
-
-  (qwen2:1.5b)
-
-- We'll use it to generate very short completions
-
-  (a few seconds of CPU)
-
-- All the challenges that we will address are also visible on longer requests
-
-  (in fact, they are even more visible on longer requests!)
-
-- We're sticking to short requests to save time and cover a lot of ground today
-
-  (but feel free to use more expensive prompts if you'd like!)
-
----
-
-## Tiny bit of backstory...
-
-The original prompt that we used when building the first version of this content was:
-
-```
-If you go to {city}, I suggest that you
-```
-
-This would typically take 10-30 seconds - and with much bigger Kubernetes nodes.
-
-Today, we suggest that we use a prompt that generates shorter answers!

-# Ollama in a nutshell
-
-https://ollama.dev
-
-"Get up and running with large language models"
-
-"Docker, but for LLMs"
-
-- Server to host (run) LLMs
-
-- Controlled with CLI or API
-
-- Download a model with `ollama pull`
-
-- Run inference with `ollama run`
-
----
-
-## Quick demo
-
-⚠️ **Important note 1:** the commands in this section aren't meant
-to be executed on your Kubernetes clusters. They are meant to
-be executed on a local machine, and they assume that Ollama is
-installed and running. If you don't have Ollama on your local
-machine, it's OK to skip these demos!
-
-⚠️ **Important note 2:** the models used by Ollama are fairly big
-(1.5 GB for the one used here; up to 10s or 100s of GB for bigger
-models). We do not recommend downloading them on conference WiFi.
-
-Assuming Ollama is installed and running:
-
-```
-ollama run qwen2:1.5b "What's the solution to global warming?"
-```
-
-We're going to use this model because it's relatively small.
-
-Many others are available (see https://ollama.dev/search).
-
----
-
-## Other useful commands
-
-- Start an interactive chat session:
-  ```bash
-  ollama run qwen2:1.5b
-  ```
-
-- Pull an model (or check for updates):
-  ```bash
-  ollama pull qwen2:1.5b
-  ```
-
-- See information on a model:
-  ```bash
-  ollama show qwen2:1.5b
-  ```
-
----
-
-## Models on disk, in memory
-
-- See models available on disk:
-  ```bash
-  ollama list
-  ```
-
-- See models loaded in memory:
-  ```bash
-  ollama ps
-  ```
-
-- Unload a model:
-  ```bash
-  ollama stop qwen2:1.5b
-  ```
-
-Models are automatically unloaded after 5 minutes (by default).
-
-Ollama loads models in RAM, and in VRAM if it detects a supported GPU.

-# Ollama on Kubernetes
-
-Let's run Ollama on our Kubernetes cluster!
-
-- Option 1: `kubectl run`
-
-- Option 2: create a Deployment and a Service
-
-- Option 3: use a Helm chart
-
----
-
-## 1️⃣ `kubectl run`
-
-Note: the `ollama/ollama` image is quite big (~2 GB transfer, ~4 GB on disk).
-
-```bash
-kubectl run ollama --image ollama/ollama
-```
-
-Wait for the pod to be up and running:
-```bash
-kubectl wait pod ollama --for=condition=Ready
-```
-
-(If that command times out, try again and/or specify a higher timeout.)
-
-```bash
-kubectl exec ollama -- ollama run qwen2:1.5b "What's Bach's best piece?"
-```
-
-Shutdown the pod:
-```bash
-kubectl delete pod ollama
-```
-
----
-
-## 2️⃣ Deployment + Service
-
-Create the Deployment:
-```bash
-kubectl create deployment ollama --image ollama/ollama
-```
-
-Create the Service:
-```bash
-kubectl create service clusterip ollama --tcp 11343
-```
-
-Wait for the Service Endpoints to be available:
-```bash
-kubectl wait endpoints ollama --for=jsonpath={..ip}
-```
-

-
-| 1 | 1 | 4 | 3 | 4 |
-|---|---|---|---|---|
-| L | L | A | M | A |
-
----
-
-## Connecting to the Service
-
-Let's use the `/api/generate` endpoint:
-
-```bash
-kubectl run httpclient --rm -it --image alpine/httpie -- --ignore-stdin \
-  http://ollama:11434/api/generate \
-  model=qwen2:1.5b prompt="Write a limerick about Kubernetes"
-```
-
-(See [Ollama API docs](https://github.com/ollama/ollama/blob/main/docs/api.md#generate-a-completion) for details.)
-
---
-
-🤔 We get an error: the model needs to be downloaded first.
-
-💡 When we used the `ollama run` CLI command earlier, it did it automatically for us.
-
----
-
-## Pulling the model
-
-Method 1:
-```bash
-kubectl exec deployment/ollama -- ollama pull qwen2:1.5b
-```
-
-Method 2:
-```bash
-kubectl run httpclient --rm -it --image alpine/httpie -- --ignore-stdin \
-  http://ollama:11434/api/pull \
-  name=qwen2:1.5b
-```
-
----
-
-## Houston, we (are going to) have a problem...
-
-- This works when there is only one pod
-
-- What happens if we scale up the Deployment?
-
-- We need to pull the model on every pod
-
-- How should we do that?
-
----
-
-## Potential solutions
-
-- Bake the model into the image
-
-  🙅 Personal opinion: this is a bad idea (image size, maintenance...)
-
-- Directly send a "pull" command to each pod, individually
-
-  🙁 Hackish, not great
-
-- Use a Kubernetes lifecycle hook
-
-  💡 That works!
-
-- Use a sidecar container to pull the model
-
-  🤔 Doable, but more work than the lifecycle hook
-
----
-
-## 🙋 Choose your own adventure
-
-Should we add that lifecycle hook?
-
----
-
-## 3️⃣ Helm chart
-
-- Let's check the [ArtifactHUB] for an Ollama Helm chart
-
-- The most popular (as of November 2024) is [this one, by OTWLD][ollama-chart]
-
-- ~~It has pockets~~
-
-- It can pre-pull models! 🎉
-
-[ArtifactHub]: https://artifacthub.io
-[ollama-chart]: https://artifacthub.io/packages/helm/ollama-helm/ollama
-
----
-
-## Installing the Helm chart
-
-Traditional method:
-```bash
-helm repo add ollama https://otwld.github.io/ollama-helm/
-helm install ollama ollama/ollama --set ollama.models={qwen2:1.5b}
-```
-
-Idempotent¹, single-command method:
-```bash
-helm upgrade --install --repo https://otwld.github.io/ollama-helm/ \
-  ollama ollama --set ollama.models={qwen2:1.5b}
-```
-
-.footnote[¹Idempotent: which can be executed multiple times without adverse effect.]
-
----
-
-## Testing the Helm installation
-
-Just like before:
-```bash
-kubectl run httpclient --rm -it --image alpine/httpie -- --ignore-stdin \
-  http://ollama:11434/api/generate \
-  model=qwen2:1.5b prompt="Write a limerick about YAML" stream:=false
-```
-
-And while we're here, check resource usage:
-```bash
-kubectl exec deployment/ollama -ti -- top
-```
-
-There should be two processes:
-
-- `ollama` itself, relatively small (~100 MB)
-
-- the LLM subprocess, relatively big (~1.4 GB for qwen2:1.5b)

-## HTTPie
-
-https://httpie.io/
-
-- CLI client to send requests to web services
-
-- Similar to curl, but made specifically to talk to API backends
-
-```bash
-httpie <URL> [key=value] [key=value] [key:=value]
-```
-
-- The `key=value` pairs get turned into a JSON object
-
-- `key:=value` indicates a parameter to be sent "as-is"

-## Sending some load
-
-We're going to use `hey`:
-
-```bash
-kubectl run hey --rm -it --image nixery.dev/hey -- \
-  hey -c 10 -n 10 -t 60 -m POST \
-  -d '{"model": "qwen2:1.5b", "prompt": "vi or emacs?"}' \
-  http://ollama:11434/api/generate
-```
-
-Some explanations:
-
-- `nixery.dev` = automatically generates images with [Nixery]
-- `-c` = concurrent requests
-- `-n` = total number of requests
-- `-t` = timeout in seconds
-
-This is probably going to take (literally) a minute.
-
-[Nixery]: https://nixery.dev/
-
----
-
-## Performance analysis
-
-- Let's start an interactive container with `hey`
-
-  (e.g., use the `alpine` image, then `apk add hey`)
-
-- Try 10 requests, with a concurrency of 1/2/4
-
-- Meanwhile, check the logs of the `ollama` pod
-
-- Some results (your results may vary depending on CPU, random seed...):
-
-  - 1 = 0.08 reqs/s, average latency: 12s
-  - 2 = 0.10 reqs/s, average latency: 18s
-  - 4 = 0.12 reqs/s, average latency: 28s
-
-- Higher concurrency = slightly higher throughput, much higher latency
-
-🤔 We need metrics!

-- Check if it's already installed:
-  ```bash
-  kubectl top nodes
-  ```
-
-- If we see a list of nodes, with CPU and RAM usage:
-
-  *great, metrics-server is installed!*
-
-- If we see `error: Metrics API not available`:
-
-  *metrics-server isn't installed, so we'll install it!*
-
----
-
-## Installing metrics-server
-
-- In a lot of places, this is done with a little bit of custom YAML
-
-  (derived from the [official installation instructions](https://github.com/kubernetes-sigs/metrics-server#installation))
-
-- We can also use a Helm chart:
-  ```bash
-    helm upgrade --install metrics-server metrics-server \
-      --create-namespace --namespace metrics-server \
-      --repo https://kubernetes-sigs.github.io/metrics-server/ \
-      --set args={--kubelet-insecure-tls=true}
-  ```
-
-- The `args` flag specified above should be sufficient on most clusters
-
-- After a minute, `kubectl top nodes` should show resource usage
-
----
-
-## 2️⃣ Historical resource usage
-
-- We're going to use Prometheus (specifically: kube-prometheus-stack)
-
-- This is a Helm chart bundling:
-
-  - Prometheus
-
-  - multiple exporters (node, kube-state-metrics...)
-
-  - Grafana
-
-  - a handful of Grafana dashboards
-
-- Open Source
-
-- Commercial alternatives: Datadog, New Relic...
-
----
-
-## Installing kube-prometheus-stack
-
-We're going to expose both Prometheus and Grafana with a NodePort:
-
-```bash
-helm upgrade --install --repo https://prometheus-community.github.io/helm-charts \
-  promstack kube-prometheus-stack \
-  --namespace prom-system --create-namespace \
-  --set prometheus.service.type=NodePort \
-  --set grafana.service.type=NodePort \
-  --set prometheus.prometheusSpec.podMonitorSelectorNilUsesHelmValues=false \
-  --set prometheus.prometheusSpec.serviceMonitorSelectorNilUsesHelmValues=false \
-  #
-```
-
-This chart installation can take a while (up to a couple of minutes).
-
----
-
-class: extra-details
-
-## `...NilUsersHelmValues=false` ???
-
-- kube-prometheus-stack uses the "Prometheus Operator"
-
-- To configure "scrape targets", we create PodMonitor or ServiceMonitor resources
-
-- By default, the Prometheus Operator will only look at \*Monitors with the right labels
-
-- Our extra options mean "use all the Monitors that you find!"
-
----
-
-## Connecting to Grafana
-
-Check the NodePort allocated to Grafana:
-
-```bash
-kubectl get service promstack-grafana --namespace prom-system
-```
-
-Get the public address of one of our nodes:
-
-```bash
-kubectl get nodes -o wide
-```
-
-In a browser, connect to the public address of any node, on the node port.
-
-The default login and password are `admin` / `prom-operator`.
-
-Check the dashboard "Kubernetes / Compute Resources / Namespace (Pods)".
-
-Select a namespace and see the CPU and RAM usage for the pods in that namespace.
-

-
-## 3️⃣ Request duration
-
-- Unfortunately, as of November 2024, ollama doesn't expose metrics
-
-  (there is ongoing discussion about it: [issue 3144][3144], [PR 6537][6537])
-
-- There are some [garbage AI-generated blog posts claiming otherwise][garbage]

-## HAProxy to the rescue
-
-- HAProxy is a proxy that can handle TCP, HTTP, and more
-
-- It can expose detailed Prometheus metrics about HTTP requests
-
-- The plan: add a sidecar HAProxy to each Ollama container
-
-- For that, we need to give up on the Ollama Helm chart
-
-  (and go back to basic manifests)
-
----
-
-## 🙋 Choose your own adventure
-
-Do we want to...
-
-- write all the corresponding manifests?
-
-- look at pre-written manifests and explain how they work?
-
-- apply the manifests and carry on?
-
----
-
-## 🏗️ Let's build something!
-
-- If you have created Deployments / Services: clean them up first!
-
-- Deploy Ollama with a sidecar HAProxy (sample configuration on next slide)
-
-- Run a short benchmark campaign
-
-  (e.g. scale to 4 pods, try 4/8/16 parallel requests, 2 minutes each)
-
-- Check live resource usage with `kubectl top nodes` / `kubectl top pods`
-
-- Check historical usage with the Grafana dashboards
-
-  (for HAProxy metrics, you can use [Grafana dashboard 12693, HAProxy 2 Full][grafana-12693])
-
-- If you don't want to write the manifests, you can use [these][ollama-yaml]

-## ⚠️ Connection queues
-
-- HAProxy will happily queue *many* connections
-
-- If a client sends a request, then disconnects:
-
-  - the request stays in the queue
-
-  - the request gets processed by the backend
-
-  - eventually, when the backend starts sending the reply, the connection is closed
-
-- This can result in a backlog of queries that take a long time to resorb
-
-- To avoid that: `option abortonclose` (see [HAProxy docs for details][abortonclose])
-
-- Note that the issue is less severe when replies are streamed
-
-[abortonclose]: https://www.haproxy.com/documentation/haproxy-configuration-manual/latest/#4-option%20abortonclose
-
----

-class: extra-details
-
-## Ad-hoc HAProxy dashboard
-
-- To consolidate all frontend and backend queues on a single graph:
-
-  - query: `haproxy_frontend_current_sessions`
-
-  - legend: `{{namespace}}/{{pod}}/{{proxy}}`
-
-  - options, "Color scheme", select "Classic palette (by series name)"
-
----
-
-## What do we see?
-
-- Imperfect load balancing
-
-- Some backends receive more requests than others
-
-- Sometimes, some backends are idle while others are busy
-
-- However, CPU utilization on the node is maxed out
-
-- This is because our node is oversubscribed
-
-- This is because we haven't specified resource requests/limits (yet)
-
-  (we'll do that later!)

-## Setting resource requests and limits
-
-- Thanks to *requests*:
-
-  - our pods will have resources *reserved* for them
-
-  - we won't pack too many pods on a single node
-
-  - cluster autoscaling will trigger when needed (if possible!)
-
-- Thanks to *limits*:
-
-  - our pods won't use more than a given amount of resources
-
-  - they won't use up all the available resources on the node
-
-  - behavior will be more consistent between loaded and unloaded state
-
----
-
-## Memory
-
-- Personal advice: set request and limit to the same value
-
-- Check current or historical usage and add a bit of padding
-
-  (the more data historical data we have, the less padding we need)
-
-- Consider 10% padding for "dataless" pods, more for pods with data
-
-  (so that the pod has "reserves" for page cache usage)
-
-⚠️ Pods hitting their memory limit will be **killed!**
-
----
-
-## CPU
-
-- It's not necessary to set requests and limits to the same value
-
-  (this would cause a lot of waste for idle workloads)
-
-- Let's see a few possible strategies!
-
----
-
-## CPU for mostly idle pods
-
-E.g.: web services, workers handling very few requests...
-
-- Set the limit to at least one whole core
-    
-  (to avoid throttling, especially on bursty workloads)
-
-- Requests can be very low (e.g. 0.1 core)
-
-⚠️ If requests are too low and the node is very loaded,
-the pod will slow down significantly!
-
-(Because CPU cycles are allocated proportionally to CPU requests.)
-
----
-
-## Inelastic CPU-hungry pods
-
-- Pods with a fixed number of threads:
-
-  *set requests and limits to that number of threads*
-
-- Pods where a specific level of performance needs to be guaranteed:
-
-  *set requests and limits to the number of cores providing that performance*
-
-⚠️ If you set limits to higher levels, performance will be unpredictible!
-
-(You'll get good performance when the node has extra cycles.)
-
----
-
-## Elastic CPU-hungry pods
-
-- Pods that could potentially use all the cores
-
-  (e.g. machine learning training and inference, depending on the models)
-
-- Decide how many pods per node you want to pack
-
-- Set CPU requests as a fraction of the number of cores of the nodes
-
-  (minus some padding)
-
-- Example:
-
-  - nodes with 32 cores
-  - we want 4 pods per node
-  - CPU request: 7.5 cores
-
-- Set limits to a higher level (up to node size)
-
----
-
-## In practice
-
-- Check memory usage of our Ollama pods:
-  ```bash
-  kubectl top pods
-  ```
-  (Or even better, look at historical usage in Prometheus or Grafana!)
-
-- Check how many cores we have on our nodes:
-  ```bash
-  kubectl get nodes -o json | jq .items[].status.capacity.cpu
-  kubectl get nodes -o custom-columns=NAME:metadata.name,CPU:status.capacity.cpu
-  ```
-
-- Let's decide that we want two Ollama pods per node
-
-- What requests/limits should we set?
-
----
-
-## Setting resources for Ollama
-
-- Assumptions:
-
-  - we want two pods per node
-  - each pod uses ~1500MiB RAM
-  - nodes have 4 cores
-
-- We'll set memory requests and limits to 2G
-
-- We'll set CPU requests to 1.5 (4 cores / 2 pods, minus padding)
-
-- We'll set CPU limits to twice the requests
-
-```bash
-kubectl set resources deployment ollama \
-  --requests=cpu=1.5,memory=2G \
-  --limits=cpu=3,memory=2G
-```
-
-⚠️ If you have an HAProxy side car, this will set its resources too!
-
----
-
-## Results
-
-- After setting these resource requests, we should see cluster autoscaling
-
-- If not: scale up the Ollama Deployment to at least 3 replicas
-
-- Check cluster autoscaler status with:
-  ```bash
-  kubectl describe configmap --namespace kube-system cluster-autoscaler-status
-  ```

-# Message Queue Architecture
-
-There are (at least) three ways to distribute load:
-
-- load balancers
-
-- batch jobs
-
-- message queues
-
-Let's do a quick review of their pros/cons!
-
----
-
-## 1️⃣ Load balancers
-
-<pre class="mermaid">
-  flowchart TD
-    Client["Client"] ---> LB["Load balancer"]
-    LB ---> B1["Backend"] & B2["Backend"] & B3["Backend"]
-</pre>
-
----
-
-## Load balancers
-
-- Latency: ~milliseconds (network latency)
-
-- Overhead: very low (one extra network hop, one log message?)
-
-- Great for short requests (a few milliseconds to a minute)
-
-- Supported out of the box by the Kubernetes Service Proxy
-
-  (by default, this is `kube-proxy`)
-
-- Suboptimal resource utilization due to imperfect balancing
-
-  (especially when there are multiple load balancers) 
-
----
-
-## 2️⃣ Batch jobs
-
-<pre class="mermaid">
-  flowchart TD
-  subgraph K["Kubernetes Control Plane"]
-    J1["Job"]@{ shape: card}
-    J2["Job"]@{ shape: card}
-    J3["..."]@{ shape: text}
-    J4["Job"]@{ shape: card}
-  end
-  C["Client"] ---> K
-  K <---> N1["Node"] & N2["Node"] & N3["Node"]
-</pre>
-
----
-
-## Batch jobs
-
-- Latency: a few seconds (many Kubernetes controllers involved)
-
-- Overhead: significant due to all the moving pieces involved
-
-  (job controller, scheduler, kubelet; many writes to etcd and logs)
-
-- Great for long requests (a few minutes to a few days)
-
-- Supported out of the box by Kubernetes
-
-  (`kubectl create job hello --image alpine -- sleep 60`)
-
-- Asynchronous processing requires some refactoring
-
-  (we don't get the response immediately)
-
----
-
-## 3️⃣ Message queues
-
-<pre class="mermaid">
-  flowchart TD
-  subgraph Q["Message queue"]
-    M1["Message"]@{ shape: card}
-    M2["Message"]@{ shape: card}

-  end
-  C["Client"] ---> Q
-  Q <---> W1["Worker"] & W2["Worker"] & W3["Worker"]
-</pre>
-
----
-
-## Message queues
-
-- Latency: a few milliseconds to a few seconds
-
-- Overhead: intermediate
-
-  (very low with e.g. Redis, higher with e.g. Kafka)
-
-- Great for all except very short requests
-
-- Requires additional setup
-
-- Asynchronous processing requires some refactoring
-
----
-
-## Dealing with errors
-
-- Load balancers
-
-  - errors reported immediately (client must retry)
-  - some load balancers can retry automatically
-
-- Batch jobs
-
-  - Kubernetes retries automatically
-  - after `backoffLimit` retries, Job is marked as failed
-
-- Message queues
-
-  - some queues have a concept of "acknowledgement"
-  - some queues have a concept of "dead letter queue"
-  - some extra work is required
-
----
-
-## Some queue brokers
-
-- Redis (with e.g. RPUSH, BLPOP)
-
-  *light, fast, easy to setup... no durability guarantee, no acknowledgement, no dead letter queue*
-
-- Kafka
-
-  *heavy, complex to setup... strong deliverability guarantee, full featured*
-
-- RabbitMQ
-
-  *somewhat in-between Redis and Kafka*
-
-- SQL databases
-
-  *often requires polling, which adds extra latency; not as scalable as a "true" broker*
-
----
-
-## More queue brokers
-
-Many cloud providers offer hosted message queues (e.g.: Amazon SQS).
-
-These are usually great options, with some drawbacks:
-
-- vendor lock-in
-
-- setting up extra environments (testing, staging...) can be more complex
-
-(Setting up a singleton environment is usually very easy, thanks to web UI, CLI, etc.; setting up extra environments and assigning the right permissions with e.g. IAC is usually significantly more complex.)
-
----
-
-## Implementing a message queue
-
-1. Pick a broker
-
-2. Deploy the broker
-
-3. Set up the queue
-
-4. Refactor our code
-
----
-
-## Code refactoring (client)
-
-Before:
-```python
-response = http.POST("http://api", payload=Request(...))
-```
-
-After:
-```python
-client = queue.connect(...)
-client.publish(message=Request(...))
-```
-
-Note: we don't get the response right way (if at all)!
-
----
-
-## Code refactoring (server)
-
-Before:
-```python
-server = http.server(request_handler=handler)
-server.listen("80")
-server.run()
-```
-
-After:
-```python
-client = queue.connect(...)
-while true:
-  message = client.consume()
-  response = handler(message)
-  # Write the response somewhere
-```
