-# Database Setup
-
-This directory contains the Kubernetes manifests to simulate a database setup
-with a primary database, read replicas, and scheduled maintenance tasks using CronJobs.
-
-## Components
-
-### Core Resources
-
-| Resource | File | Description |
-|----------|------|-------------|
-| ServiceAccount | `serviceaccount.yaml` | Shared service account for all database workloads |
-| PVC | `pvc-primary.yaml` | 1Gi persistent storage for primary database |
-| StatefulSet | `statefulset-primary.yaml` | Primary database with persistent storage at `/data` |
-| Deployment | `deployment-replica.yaml` | Read replica deployment |
-| Service (Headless) | `service-primary.yaml` | Headless service for StatefulSet |
-| Service | `service-replica.yaml` | ClusterIP service for replicas |
-| HPA | `hpa-replica.yaml` | Autoscaler for replicas (2-3 pods, 99% CPU) |
-
-### CronJobs
-
-| CronJob | Schedule | Duration | TTL Cleanup | Description |
-|---------|----------|----------|-------------|-------------|
-| `rollup-daily` | Every 10 min | ~1 min | 1 hour | Daily rollup simulation (6 iterations) |
-| `rollup-weekly` | Every 30 min | ~2 min | 1 day | Weekly rollup simulation (12 iterations) |
-| `backup-daily` | Daily at midnight | ~1 min | 1 day | Backup simulation (configured to fail) |
-
-### Scripts
-
-Located in `scripts/` directory:
-
-- `rollup.sh` - Rollup simulation script with configurable steps via `ROLLUP_STEPS` env var
-- `backup.sh` - Backup simulation script with configurable exit code via `BACKUP_EXIT` env var
-
-## Labels
-
-All resources use Kubernetes recommended labels:
-
-- `app.kubernetes.io/name` - Component name
-- `app.kubernetes.io/part-of: database` - Part of database application
-
-## Configuration
-
-### Primary Database
-- **Port**: 3306 (MySQL standard)
-- **Storage**: 1Gi PersistentVolumeClaim mounted at `/data`
-- **Service**: Headless (`clusterIP: None`) for StatefulSet
-
-### Replica Database
-- **Port**: 3306
-- **Scaling**: HPA with 2-3 replicas at 99% CPU utilization
-- **Service**: ClusterIP
-
-### CronJob Scripts
-
-The scripts check database-replica health before running:
-
-```sh
-podcli check http database-replica:3306/readyz
-```
-
-## Usage
-
-Deploy with Kustomize:
-
-```bash
-kubectl apply -k deploy/bases/database
-```
-
-Or include in an overlay:
-
-```yaml
-# kustomization.yaml
-resources:
-  - ../../bases/database
-```

 ## Configuration
 
-The provided [docker-compose.yaml](docker-compose.yaml) sets up 6 containers:
+The provided [docker-compose.yaml](docker-compose.yaml) sets up 4 Containers
 
 1. PodInfo Frontend on port 9898
 2. PodInfo Backend on port 9899
 3. OpenTelemetry Collector listening on port 4317 for GRPC
-4. Jaeger all-in-one with UI on port 16686
-5. Loki on port 3100
-6. Grafana on port 3000
+4. Jaeger all-in-one listening on multiple ports
 
 ## How does it work?
 
-The frontend pod is configured to call the backend pod. Both podinfo pods send traces
-and logs to the collector at port 4317 using OTLP gRPC.
-
-The collector forwards:
-- **Traces** to Jaeger via OTLP gRPC on port 4317
-- **Logs** to Loki via OTLP HTTP on port 3100
-
-Jaeger exposes its UI on port `16686`. Grafana exposes its UI on port `3000` and is
-pre-configured with both Jaeger and Loki as datasources.
+The frontend pods are configured to call onto the backend pods. Both the podinfo
+pods are configured to send traces over to the collector at port 4317 using GRPC.
+The collector forwards all received spans to Jaeger over port 14250 and Jaeger
+exposes a UI over port `16686`.
