Java EE and Microservices

Refactor monolith to microservices

This workspace will show how to refactor a Java EE monolith to a microservices-based application. This will be accomplished in multiple phases:

1. Phase 1: Functional decomposition of a WAR into multiple `WAR`s. Use hardcoded service URIs.

2. Phase 2: Use service registration and discovery

3. Phase 3: Continuous integration

4. Phase 4: Continuous deployment

5. Phase 5: Proactive monitoring and scale in/out

6. Phase 6: Change the implementation stack of a service

Run the application

1. Start ZooKeeper

   docker run -d -p 2181:2181 fabric8/zookeeper

2. Download and unzip WildFly 9.0.0.Final

3. Run WildFly

   ./bin/standalone.sh

4. Deploy the application

   mvn -f microservice/pom.xml install -DskipTests

NoOps

Operational concerns are addressed in the following documents:

1. Service Discovery

2. Continuous Integration

3. Continuous Deployment

4. Service Monitoring
