What is a characteristic of a microservice?

A microservice is characterized as a bite-sized service that performs a specific task, which aligns perfectly with option B. This design principle aims to decompose complex applications into smaller, independent units that can each be developed, deployed, and scaled independently. Each microservice is responsible for a distinct business capability or function, making it easier to manage and update the application as a whole. Such an architectural style enhances flexibility and allows for various technologies and programming languages to be used as needed across different services.

In the context of modern software development, this allows organizations to respond quickly to changes and innovate more efficiently by enabling separate teams to work on different microservices concurrently without interfering with one another. This modularity also contributes to easier troubleshooting and maintenance, as issues can be isolated to specific services without affecting the entire system.
