What is the purpose of a microservice?

Microservices are an architectural style that structures an application as a collection of loosely coupled services, each focused on a specific business functionality. The purpose of a microservice is to take input, process it, and produce output in a way that allows for independent development, deployment, and scaling. This design facilitates better resource management and can enhance the performance and reliability of applications.

Each microservice can handle its own processes and data, making it easier to develop, test, and maintain applications by enabling smaller teams to work on individual services without being hindered by the complexities of the entire system. This decentralized approach also allows for a range of technologies to be employed, supporting a more agile development process.

While managing user data, serving as a server, and securing network communications are important aspects of software applications, these functions are not exclusive to microservices and do not capture the primary purpose behind their design. The focus of microservices is fundamentally on processing input to generate desired outputs through modular and independent service components.
