What is REST

REST uses a generic and uniform method of exposing resources through URIs, representation through headers, and actions through verbs such as GET, POST, PUT, DELETE, and PATCH.

• It minimizes the coupling between client/server.
• Being stateless, REST is great for horizontal scaling and partitioning.
• Often used for public HTTP APIs
