Microservices

Microservice is a form of service-oriented architecture style, loosely coupled distributed service wherein a large application is split into small applications, communicating to each other normally by rest API.

Distributed microservice architecture is built to solve the complicity of large monolithic applications.

Example image:

The application is split into four different modules such as account service, product catalog, cart server, and order server. All the mentioned modules are different from each other and are represented as separate microservices that have unique databases.

Benefits of Microservices:

1. Microservices improve your architecture’s scalability. The smaller modules are the easier for developers to code and maintain. These are not dependent on any coding language, the developers can use the programming language that they are most familiar with or the one that suits a particular service.
2. When there is a change required in a particular part or section of the application, only the corresponding section can be redeployed and modified, so there is no need to change the entire application.
3. Microservices are easy to deploy as each module is smaller we can deploy it much faster and hence help in CI/CD.
4. Microservices are easy to understand by developers as each module is smaller, they can understand the functionality of each service easily.

Microservice Frameworks:

1. Java - Spring Boot

2. Python - Django, Fast API

3. PHP - Laravel
