What Kubernetes features, patterns, and training helped our monolith migration?

[Richard_M]

My team is migrating our legacy monolithic application to a microservices architecture, and we've decided to use Kubernetes for orchestration, but the learning curve for our mostly junior-to-mid-level DevOps engineers is proving steeper than anticipated. We have the basic pods and deployments running, but we're struggling with more advanced concepts like implementing proper network policies for service-to-service communication, setting up efficient autoscaling based on custom metrics, and managing persistent storage in a multi-zone cluster without downtime. For engineers who have successfully navigated this transition, what were the most critical Kubernetes features or design patterns you adopted early on that paid off in stability and scalability? How did you structure your training and documentation to bring the team up to speed, and are there any specific tools or operators for monitoring and security that you now consider indispensable for production workloads?
