Microservices

​​Overview

Microservices architecture is a design pattern in which a website or application is divided into smaller, independent components known as microservices that may be created and deployed individually. This approach to web architecture is designed to improve the scalability, maintainability, and flexibility of an application by allowing different components to be developed, tested, and deployed independently.

Components of microservices architecture

There are several key components that make up a microservices architecture. These include the following:

Microservices

These are the smaller, independent components of the application, which are designed to perform a specific function or task. Each microservice is self-contained and communicates with other microservices through well-defined APIs.

API gateway

This is the component that sits between the client and microservices, routing requests from the client to the appropriate microservice and returning the response to the client. The API gateway can also handle tasks such as authentication, authorization, and rate limiting.

Service registry

This is a component that maintains a list of all of the available microservices and their current status. This allows the API gateway to route requests to the appropriate microservice and ensures that the application can continue to function even if some microservices are unavailable.

Load balancer

This is a component that distributes incoming requests evenly across multiple instances of a microservice, improving the performance and scalability of the application.

Database

This is a system for storing and organizing data, such as user information or content for the website. Each microservice typically has its own database, allowing it to be more independent and scalable.
