The advantages of Microservices are not a tool, rather a way of thinking when building software applications. Let's begin the explanation with the opposite: if you develop a single, self-contained application and keep improving it as a whole, it's usually called a monolith. Over time, it's more and more difficult to maintain and update it without breaking anything, so the development cycle may...
Microservices are not restricted to any one programming language, so they are language agnostic. Each service in a microservice architecture may be written in a different language that supports the chosen communication mechanism, and each service is independent.
Scalability: Each service can be deployed and scaled independently, as required.
Fault isolation: A fault in one microservice does not affect the other microservices.
Ease of deployment: The application is divided into small services, so the application can be deployed quickly and easily.
Unlimited iterations: The application can be quickly iterated and added new features without affecting other parts of the application.
Unit testing: since microservices are separate applications focused on a particular goal, it is simpler for a developer to develop test scripts to ensure that functionality.
Ease of maintenance: A microservice can be updated or replaced without affecting the other services in the application.
Improved performance: Each service can be implemented to optimize a specific function or workflow. For example, you can use a faster database for one service without affecting the other services.
