Kubernetes is an open-source platform for automating the deployment, scaling, and management of containerized applications. To successfully implement a container-based environment (Kubernetes), the following key points should be considered:
- Ensure expertise in the teams managing the infrastructure (Training).
- Ensure appropriate persistence for each workload, especially for stateful services (e.g., databases) to avoid unexpected issues.
- Adapt the storage type to the workload to optimize performance.
- Proper sizing of cluster resources, requirements, and the coexistence of various workloads.
- Consider traceability and monitoring needs from the start of the project.
- Ensure the same backup/restore capabilities as in a traditional environment.
- Define a gradual transformation plan to a microservices-based model (avoid a “Big Bang” approach).
- Follow GitOps methodologies for configuration management.
- Implement appropriate change management processes (avoid continuous and uncontrolled changes in production).
- Define a suitable CI/CD strategy (Agile).
- Avoid silos and anti-DevOps patterns, ensuring the transformation drive comes from all work areas (system administration, developers, etc.).
