Are microservices RESTful?

[mouakter13]

Stateless Microservices: These are the building blocks of distributed systems. They do not maintain or store any session state between two requests, hence the name “stateless” microservices. Also, even if a service instance is deleted, the overall processing logic of the service is not affected. This is why distributed systems take advantage of stateless microservices.
Stateful Microservices: Stateful microservices maintain or store session state or data in code. Microservices that communicate with each other always maintain service requests.
Stateless microservices are more widely used, but you can use stateful ones for multiple scenarios.

For example, suppose a customer places an order. Here “order” represents a microservice. Then, the order service starts checking the status of the product using another service, the inventory service. When greece whatsapp number data each request is independent of future or previous requests, it means that the system follows a stateless architecture.

When you try to get product information via a call, you will get the same result regardless of previous requests or context. And even if an order fails, it won’t jeopardize overall business processing. Another microservice will be ready to keep the process running.

Well, not necessarily. Let's briefly review the differences:

Microservices: A collection of functions and services that act as building blocks of an application.
RESTful APIs: They represent the protocols, commands and rules to integrate all microservices into a single application.
Microservices are all about the design style and architecture of an application, and you can build microservices with or without using a RESTful API . That being said, using RESTful will make developing loosely coupled microservices much easier.

RESTful APIs came about before microservices. They assume that all objects have uniform interfaces and are completely language-agnostic and loosely coupled. Here, the semantics and interfaces remain the same, and the API implementation can easily change at any time without affecting consumers. Therefore, RESTful and microservices may solve different problems, but they can work together.
