Event Driven Architecture with Spring Boot

Architecture Design

1. Frontend only communicates with Backend (BFF) - REST API
2. Backend can then communicates with all other lower level Services using ActiveMQ - Pub/Sub
3. All the lower level Services are - Inventory, Order (i.e Assignment) & Amazon
4. The communication media between all the lower level Services is ActiveMQ - Pub/Sub

High Level Design

REST API

Frontend -> Backend

ActiveMQ - Pub/Sub

Backend -> <- Inventory -> <- Order -> <- Amazon

Tech Stack

1. Frontend -> React
2. Backend -> REST API, Spring Boot, ActiveMQ
3. Inventory -> Spring Boot, Mongodb, ActiveMQ
4. Order -> Spring Boot, Postgres, ActiveMQ
5. Amazon -> Spring Boot, Mongodb, ActiveMQ

Install & Run

You can build all the child modules using parent pom.xml and then run all the application using the following commands,

mvn package
docker-compose up --build
