Imagine breaking down a single function unit into multiple mini-service units. That is exactly what microservices do to the traditional monolithic architecture. But, there is more to it than meets the eye. Microservices are the go-to solution for all the major software development projects. But even though it serves a major purpose, there are certain challenges across the way which need to be addressed. And as one design a microservice architecture along the way, one learns several microservice design patterns which can not only improve the performance but also ease the life of the developer. But before we delve deeper into the architecture design patterns, let’s understand the basic principles to keep in mind when we design a microservice architecture.
