How to run the application using Docker

1. Run mvn clean package -DskipTests to build the applications and create the docker image locally.
2. Run docker-compose up -d to start the applications.

How to run the application without Docker

1. Run mvn clean verify -DskipTests by going inside each folder to build the applications.
2. After that run mvn spring-boot:run by going inside each folder to start the applications.

We introduce an API Gateway below.

Benefits of API Gateway shown below.

Secure Services by adding an Auth Server (KeyCloak)

Introduces Circuit Breaker for resilient communication between services. Open state = Won't allow calls for a certain duration Half Open = Goes to this state after being in Open State for a certain duration

Introduces a way to track down issues related to performances using distributed tracing (tracks request from start to finish). Uses Spring Cloud Sleuth and Zipkin (UI to visualize this information)

Implement event driven architecture

Dockerize the components
