advantages and disadvantages of using Microservices ?

Microservices architecture is a design pattern. Cohesion and coupling are important because a good design will always have high cohesion and low coupling. To understand this, we need to understand what cohesion and coupling are.

Cohesion is nothing but the bond between an application or an intra bond within an application. For example, a molecule, inside a molecule, we have atoms. These atoms, how closely are they bonded to each other?

This bond is what is referred to as cohesion. Cohesion should be high when you talk about a microservice. That means we are referring to the fact that the interdependency inside a container, the database, and the service that is running how closely or how bonded are they with each other?


If they are closely bonded, that is good for the microservice. When you take a look at it from a bigger picture, you are talking about different microservices.

The bond between these microservices should be below. The interbond between two applications in microservices should be loose. This is referred to as low coupling. The interbond inside a container is cohesion, while interbond between two different applications or containers is coupling. That is why when you want a good design, you need high cohesion and low coupling.
