This document discusses Eclipse MicroProfile, a specification that optimizes Enterprise Java for microservices architectures. It introduces key MicroProfile specifications including Config, OpenTracing, and Metrics. Config allows configuration from sources like etcd. OpenTracing provides distributed tracing across services using tools like Jaeger. Metrics monitors system parameters and exposes them in formats like Prometheus. The document demonstrates these features and concludes that MicroProfile provides an easy way to integrate common CNCF projects into Java applications.
