Distributed Data Bus

Architecture

Features

gRPC

Used for synchronous communication between API Gateway and microservices, due to its lightweight nature

Asynchronous messaging - RabbitMq

1. Easy scalable - multiple consumer instances can be added as needed to handle request pick
2. Resiliency - if one service fails on an asynchronous system, other services will not be affected. The task will be held until the service is up and running again.

API Gateway

Stateless API Gateway to the system act as single entry point for the clients

Benefits:

1. Horizontal scalability
2. Cache
3. Rate limitting - protection against Denial Of Service (DOS) attacks and degraded performance due to traffic spikes
