What are Microservices?

Microservices are a way of building applications as small, independent services that communicate with each other over a network.

Instead of creating one large application (monolith), the system is split into smaller services, each responsible for a specific business task.

Each Microservice:

Each service focuses on a single business capability

Can be developed, deployed, and scaled independently

May use different programming languages or frameworks

Works like a small application on its own

Each service handles a single business feature (e.g., user login, payments, products).

Services communicate with each other using APIs.

Teams can choose the best technology for each service.

Services can be updated or scaled independently, reducing risk and improving reliability.
