What you'll learn

Moving a Spring Boot application from development to production involves much more than deploying a JAR file. Modern production environments demand fast startup times, optimized container images, environment-specific configuration, health checks, metrics, and distributed tracing — and without these, you're deploying blind. In this course, Deploying and Observing Spring Boot 4 Applications, you'll gain the ability to prepare Spring Boot 4 applications for production deployment with comprehensive observability. First, you'll explore how to build and package applications using Maven, ahead-of-time compilation, and GraalVM native images for dramatically faster startup. Next, you'll discover how to containerize your application with Spring Boot's Build Image support, configure it for multiple environments using profiles, and add health checks and custom metrics with Actuator and Micrometer. Finally, you'll learn how to implement distributed tracing with OpenTelemetry and deploy your fully observable application to Kubernetes. When you're finished with this course, you'll have the skills and knowledge of Spring Boot 4 deployment and observability needed to confidently take applications from local development to production-ready, monitored services running in the cloud.
