Microservices, also known as the microservice architecture, is an architectural style that structures an application as a collection of loosely coupled services. This approach allows for more flexible, scalable, and manageable applications.

In a monolithic architecture, all software components are interconnected and interdependent. If any component or single application’s function fails, the complete application could go down. Imagine you have a web application including functions like payment, history, and log in. If “history” function consumes more memory, the entire application would have to experience the same issue.
