Microservice Patterns - Implemented by Eclipse MicroProfile

Microservice Patterns - Implemented by Eclipse MicroProfile

Eclipse MicroProfile provides specifications for the most commonly used microservice patterns. This session presents a group of patterns that will be explained and demoed live in a down-to-earth and easily understandable way.

Patterns covered include Service per Container, Externalized Configuration, Health Check API, Application Metrics, Circuit Breaker, Access Token, Distributed Tracing.

There will be live coding and demo of all technologies implementing the patterns.
