Microservice architecture explained

Hello guys, if you are using Microservice architecture and want to learn about different Microservice design patterns and principles to better architect your application then you have come to the right place.

Earlier, I have talked about Monolith vs Microservice architecture, and in this article, I am going to share the essential Microservice design principle and patterns.

We will cover patterns like Event Sourcing, Circuit Breaker, SAGA, CQRS, Strangler, Database per Microservices, Backend for Frontend (BFF), Service Discovery, and API Gateway and principles like Scalability, Flexibility, Resiliency, etc.
