Explore code shrinking techniques for Jakarta EE and MicroProfile microservices in this code-only session from Devoxx Poland 2019. Learn how to leverage cloud and microservice architectures to simplify and reduce codebase size. Watch as a Jakarta EE + MicroProfile microservice is built from scratch, incorporating features such as OpenAPI, error handling, metrics, fault tolerance patterns, JSON serialization, asynchronous or reactive client, health checks, and cloud-native configuration. Discover how to create kilobyte-sized WARs and optimize your microservice development. Engage with the presenter through a highly interactive Q&A format, perfect for developers seeking practical insights into efficient microservice implementation.
