It’s been an incredible journey so far. Chapter after chapter, we have gone through patterns, principles, and best practices for working with cloud native applications, and we’ve built a bookshop system using Spring Boot and Kubernetes. It’s time to prepare for production. Part 4 guides you through the last few steps to make your cloud native applications production-ready, addressing concerns like observability, configuration management, secrets management, and deployment strategies. It also covers serverless and native images.
