    \u201cOpen Source is most successful when is played as a positive sum game\u201d (Sarah Novotny)

    This web started in 2018, after finishing my first relevant project on cloud computing with a well known consulting firm. It was an international project coordinated from Munich with remote work from other european countries and regular flights. The client was a major multinational car manufacturer with a big investment in OpenShift and Cloudbees/Jenkins infrastructure. Our role was to help the client with their pretty large CI/CD ecosystem while also implementing a new self-service developer platform, involving areas of development and operations and within a DevOps model. Requirements and way of working included continuous improvement, standardization, boilerplates and automation with a GitOps pattern, a highly recommended approach specially in demanding projects like this with hundreds of real microservices, a large number of IaC & CI/CD pipelines, hundreds (thousands?) of developers and millions of end users.

    Since then I try to apply in my country what I learnt from the germans and other european colleagues.

    I\u2019m not a freelancer and most of the time I work as a contractor, which in Spain means to be hired as an employee by an external company.

    Suggesting improvements and best practices or applying quality standards and automated solutions that work well and are easy to verify shouldn\u2019t penalize a career, but it\u2019s terribly common. I am concerned about working with some colleagues or managers who consider it a threat, generating absurd conflicts, blame games and acting in bad faith or stupidly distorting the purpose of the project.

    In a service driven IT sector (with calculated ambiguities and many hidden interests) the product is the hours billed by the consultant, being almost irrelevant the content of the job and the delivered quality. It is thus too common to find technical solutions under the policy of applying \u201cthe most difficult, non-standard, slowest and most obfuscated way possible\u201d as a competitive element (the hard way and doing weird things). This does not scale. Being ambiguous in JDs (not to say dishonest) without clarifying the real content of the job is easy and very well paid.

    Ambiguities about DevOps term. Development of new ad-hoc devops tools and ad-hoc monitoring solutions should not be the role of devops specialists. DevOps professionals develop IaC and CI/CD pipelines with standard tools and code, ideally with a cattle service model, GitOps patterns & kubernetes among other responsabilities such as application monitoring. The development of devops tools for kubernetes with i.e. client-go should be clearly mentioned in a JD as \u201csoftware development of devops tools for kubernetes with client-go\u201d (suitable for a software engineer with client-go skills, a developer of devops/kubernetes/monitoring tools). In addition, a DevOps specialist should not be a fullstack developer who occasionally does QA + DevOps + Cloud Design/Ops. Moreover, avoid confusing terms to justify these different backgrounds by creating two roles like DevOps Software Developer and DevOps SysAdmin. Maybe DevOps should be renamed as OpsDev to avoid misunderstandings.

    A tech stack is not relevant compared to the way technology is managed. You could have the best tool and run into trouble by taking the risk of applying an unsupported or not recommended1 approach.

    DevOps principles: People, processes, technology

    GitOps principles: Correctness, doing DevOps correctly

    Principle Focus Main Tool Other Tools Flexibility Correctness DevOps Automation and frequent deployments CI/CD pipeline Supply chain management, Cloud Configuration as Code, etc. Less strict and more open Less focus on correctness GitOps Correctness; doing DevOps correctly Git Kubernetes, Controller (e.g., Operator), separate CI/CD pipelines, Infrastructure as a Code, etc. Stricter and less open Designed with correctness

    The SRE Experience Is Changing with Cloud Native:

    Site Reliability Engineer (SRE) team Developers Operations team Provide and teach effective use of platform tooling to empower developers to be self-sufficient Treat SREs as application operation partners, not only as first responders to incidents Provide self-service platform deployment and observability, and enable visibility into ramifications of actions Document clear escalation paths for developers struggling in production Turn to ops teams for the \u201cpaved path\u201d or centralized developer control plane Provide opinionated \u201cpaved path\u201d platform or developer control plane (DCP), but allow developers to swap platform components if they also want to be accountable

    Avoiding standardization, automation and improvements because rivals do not invest in them is shortsighted. It is worrying because there is considerable resistance to change along with employment discrimination to prevent new proposals from succeeding. The term DevOps first appeared in 2009.

    In this service driven IT sector, cloud certifications and technical assesment tests have much more weight in the selection processes that have little to do with real work. They are mostly a wall to justify the hiring of less experienced (younger and cheaper) employees. Fundamental in any profession to learn by doing while building a career and skills with decent opportunities and without too many difficulties and barriers.

    A consequence of these technical assessment tests is the willingness to learn how to pass them while only implementing and practicing this specific knowledge at work. If assessments are about low level concepts then there\u2019s no interest in abstractions, frameworks and enterprise standards (real work). Similar scenario when evaluating kubernetes knowledge with manual tasks (CLI) instead of gitops pipelines (real work2).

    Inbreeding is not a good strategy in IT. Hiring people with different background and skills is a better bet. Cronyism, kiss up kick down and blame games hurt employee retention and economic growth. This is terrible common too. If an employee doesn\u2019t trust their manager, the company suffers. Sure, ruling through fear works, but the employee will do the bare minimum amount of work needed to keep their job (manually and without automation).

    Culture of mutual trust is key to beating competition and increasing employee retention. When something isn\u2019t right the employee should be able to bring it up without being afraid of being fired.

    We are in business to make money, perhaps not only creating value on financial markets with jargon like margin and cost effective, common in financially driven companies.

    Everyone sells the same thing: cloud, devops, big data, etc. Speaking is cheap. Throwing an SQL statement doesn\u2019t make you an SQL expert. Likewise, you don\u2019t need to be an SQL expert on every job. Actually most of the jobs require generalists rather than specialists, above all in countries where most companies are SMEs.

    There are very few unicorns and to a certain extent it depends a lot on the environment created.

    CKA is the top Kubernetes certification but only a few employers require one. Same logic applies to other certifications.

    It is surprising the numerous resources and the strategy of psychological exhaustion of recruitment companies that continuously bombard us with interviews. They also force us to transfer our data to third parties without any control of where our CV ends. It is also very common to gather information from detailed CVs and interviews to afterwards publish similar JDs that can be sold as services to potential clients. Again, only the service name is what matters, not how this is implemented and whether the client have the capacity to implement it in a proper manner.

    As professionals we are obliged to a high commitment to our clients, sometimes sacrificing our well-being in order to achieve the objectives. Everyone has limits, sometimes being a personal decision to abandon a project without this entailing a penalty in the next job (we have given our CV to third parties without any control). An unfair bad reference (blame games) and calculated ambiguities can ruin our careers. And I\u2019m not talking about an isolated case.

    Losing employment and significantly penalizing employability and economic bargaining power for defending the value of automation, continuous improvement and standardization in computer engineering is a high price to pay. The alternatives often seem to be manual work with low salary expectations, lack of opportunities with new cloud jobs (better paid), promotion to a management position or emigration to countries with a different economic model (where technical jobs are better valued). This does not scale either. Freelancing worldwide is not for everyone either.

    \u201cOne of the biggest problems in IT is that we keep reinventing the wheel. We are running the same circles, producing similar technologies to solve the same problems. Reinventing the wheel is a great way to learn how the wheel works, but not an efficient way to build software\u201d (@dmokafa)

    \u201cTech industry thinks throwing more tools to the problem is the solution. More tools = more failure modes\u201d (@rakyll)

    Instead of reinventing the wheel by rewriting from scratch a new installer or ad-hoc devops tool to manage/monitor kubernetes, please pay attention to the links shared here and learn how to add value on the so called day 2. You will find solutions and knowledge in a practical and efficient way without being totally essential to obtain a certification to successfully complete the task. For example, if there\u2019s money for reinventing the wheel on day 1, then there\u2019s money for investing in these high value added solutions on day 2 where automation can significantly improve our lives and the quality of the delivered service. Automation is also a key element when evaluating the delivery of a service.

    Nubenetes shares relevant information that helps spread the new technological and cultural standards, in order to eliminate bottlenecks and silos and promote digital transformation.

    Does saying this publicly imply being blacklisted and losing professional opportunities? What kind of society do we live in?

    Tips: ask the hiring manager what experience they have with Cloud Automation, Cloud Managed Services and K8s in Production, if they deploy OpenShift via IPI1 or UPI, whether they are familiar with Gitops as the correct way of doing DevOps, if they work with modern, easy-to-use automation tools (terraform, ansible modules with YAML/Jinja templates, argocd, helm, an automation server3 to run pipelines, declarative code in Jenkins4 Pipelines or in DevOps Azure Pipelines, IaC boilerplates instead of k8s vanilla, etc) or they are not practical and prefer to develop their own ad-hoc tools with millions of lines of code that need maintenance (by who?). If any doubt, ask them to show you their pipelines and custom solutions, how long it takes them to deploy and setup their k8s infra on day 1 & day 2 (pets vs cattle service model), how long it takes them to deploy a single app and if the process is fully automated or not, what monitoring solutions they have, if security and Role-based Access Control (RBAC) are implemented in their k8s clusters, whether changes and PoCs are tested first in ephemeral and isolated K8s/Cloud infra test environments with IaC & CI/CD pipelines, if solutions can be discussed within the team, etc.

    \u201cI am a big fan of the scientific method. Engineers do not build bridges from a right or left perspective, the engineer builds bridges from an evidence-based perspective and over time bridge construction has improved. On the other hand, a politician does things from a right or left perspective, and over time politics has gotten worse. When I work with politicians and two of them are in a room together, one always thinks of the other, \u201cwill they get in my way? Will they damage my reputation? Is there a conflict of interest?\u201d On the other hand, when two engineers meet, they say, \u201chello! I have a problem, can you help me?\u201d Engineers rely on evidence.

    What is DevOps compliance? DevOps compliance refers to the process of integrating compliance and security requirements into DevOps practices. DevOps is a methodology that emphasizes collaboration and communication between development, operations, and other teams involved in the software development process. It aims to deliver software quickly and reliably through continuous integration, testing, and deployment.

    DevOps compliance is important because it ensures that the software being developed adheres to regulatory and security standards. This can include compliance with laws such as HIPAA or GDPR, industry-specific regulations, or organizational policies.

    DevOps compliance involves implementing security and compliance requirements into the DevOps workflow. This includes incorporating compliance checks and security testing into the development process, as well as ensuring that security and compliance concerns are addressed throughout the entire software development lifecycle.

    In summary, DevOps compliance is about balancing the need for speed and agility in software development with the need to meet regulatory and security requirements. It enables organizations to deliver software that is not only innovative and efficient but also meets the necessary compliance standards.

    What is the best strategy for cloud managers? Gitops or ClickOps? As an AI language model, I cannot make a definitive recommendation between GitOps and ClickOps as the \u201cbest\u201d strategy for cloud managers, as each approach has its own advantages and disadvantages depending on the specific needs and goals of the organization. However, I can provide an overview of the two strategies to help you understand their differences and choose the one that best fits your needs.

    GitOps is an approach that emphasizes using Git as the source of truth for managing infrastructure and application deployment. In this approach, changes to the infrastructure or application are made via pull requests in Git, and the changes are automatically deployed to the cloud environment based on the Git commit history. GitOps enables version control of infrastructure and application configurations, and it facilitates collaboration between team members. However, it requires a significant investment in automation and tooling to set up and maintain the GitOps pipeline.

    ClickOps, on the other hand, is an approach that relies on graphical user interfaces (GUIs) and point-and-click actions to manage cloud resources. This approach is typically more accessible to non-technical users and can provide a more straightforward and intuitive interface for cloud management. However, ClickOps can be more error-prone, as it does not provide the same level of visibility and transparency as GitOps, and it can be more challenging to maintain consistent infrastructure and application configurations.

    Ultimately, the choice between GitOps and ClickOps depends on the specific needs and goals of the organization, as well as the level of technical expertise of the team. For organizations that value version control, collaboration, and automation, GitOps may be the better choice, while ClickOps may be a more accessible and user-friendly option for teams with less technical experience. It is also worth noting that many organizations use a combination of both approaches, depending on the specific use case and context.

    "},{"location":"chatgpt.html#gitops-vs-clickops-2","title":"GitOps vs ClickOps 2","text":"

    GitOps and ClickOps are different approaches to infrastructure management and application deployment in the cloud.

    GitOps focuses on automation and managing infrastructure as code (IaC) using Git as a single source of truth for configuration and version control. In this approach, changes to the infrastructure are made by updating the Git repository and the implementation of changes is automatically done through CI/CD tools.

    ClickOps, on the other hand, focuses on manual and visual management of infrastructure and application deployment using graphical user interfaces (GUIs). This approach allows developers and IT operations teams to make changes and deploy applications quickly and easily without the need for knowledge of the underlying technical details.

    The problem between GitOps and ClickOps lies in how infrastructure management and application deployment are approached. GitOps is more automated and focused on IaC, which can result in greater efficiency and a reduction of human errors. ClickOps is more manual and visual, which can be easier to use and understand for teams who do not have programming and automation experience.

    In summary, both approaches have their advantages and disadvantages and are suited to different situations and needs. It depends on the preferences and skills of the development and IT operations team to choose the appropriate approach for their organization.

    Some of the things I like about @Podman_io is this ability to generate K8s pod YAMLs from podman pods.(1): deploy a pod named webserver with an Nginx container.(2): generate the K8s YAML for the podman pod(3): You can direct the generated YAML to a file with redirection pic.twitter.com/PTykINAS4A

    Kubernetes has made huge improvements in the ability to run stateful workloads including databases and message queues, but I still prefer not to run them on Kubernetes.

    I'm super curious, how many people have successfully migrated their databases from Oracle to Postgres in production? I'm talking 100% migration with Oracle being turned off at the end.

    \u2014 Kelsey Hightower (@kelseyhightower) November 1, 2021

    Kubernetes can only meet stateful services half way. We need direct changes in databases, message brokers, and other stateful systems if we want to see a future where Kubernetes becomes the preferred destination to run them. The @vectorizedio team is doing their part. https://t.co/w94Q56nnXM

    \u2014 Kelsey Hightower (@kelseyhightower) November 8, 2021

    Sometimes we work for a database and need to connect to another (#migration ;) so I explained to a colleague the difference between Oracle SERVICE_NAME and SID. Pasting it here in case it helps \ud83e\uddf5
