Overview on the Microservice architecture

1. Store - Web app that retrieves information on the device types from Samsung and Apple microservices to displays them on Java server pages.
2. Eureka server - A discovery server responsible for holding instances of microservice clients and providing easier navigation.
3. Samsung - Extracts the list of JSON Device objects gathered from Samsung persistence.
4. Samsung2 - Extra copy of Samsung to test client-side load balancing.
5. Apple - Extracts the list of JSON Device objects gathered from Apple persistence.
6. Apple persistence - Gathers information from MySQL server on apple devices providing a list of JSON Device objects.
7. Samsung persistence - Gathers information from MySQL server on Samsung devices providing a list of JSON Device objects.

Extract microservices and import into IDEs

1. Import each microservice folder except into a separate Intellij Maven project.
2. Import Store microservice into Eclipse.

How to run Store

3. Start the Eureka server in IntelliJ.
4. Start Store in Eclipse.
5. Start remaining microservices in IntelliJ.
6. Go to the Eureka server page. You should have the following 5 applications running below:

7. Go to the Store page and click on either Samsung or Apple.
