Microservices Architecture Development is a software design approach where a large application is built as a collection of small, independent services. Each service focuses on a specific business function (such as authentication, payments, user management, or notifications) and communicates with other services through lightweight APIs, typically REST or messaging queues.
Unlike monolithic systems, microservices allow each component to be developed, deployed, and scaled independently. This makes applications more flexible, easier to maintain, and more resilient—because a failure in one service does not necessarily bring down the entire system.
It also enables teams to work in parallel on different services, supports multiple programming languages, and improves scalability for high-traffic systems by allowing only the required services to be scaled instead of the whole application.
