Monolith to microservices

An API is a contract that provides guidance for a consumer to use the underlying service. A microservice is an architectural design that separates portions of a (usually monolithic) application into small, self-containing services.

In microservices architecture, each application is designed as an independent service. REST is a valuable architectural style for microservices , thanks to its simplicity, flexibility, and scalability.

Microservices are an architectural and organizational approach to software development where software is composed of small independent services that communicate over well-defined APIs . These services are owned by small, self-contained teams.
