Microservices architecture is a modern software design approach that structures an application as a collection of small, independent, and loosely coupled services, each focused on a specific business capability. In this paradigm, applications are broken down into modular components, or microservices, that can be developed, deployed, and scaled independently. Each microservice operates as a self-contained unit, communicating with others through well-defined APIs, promoting flexibility and agility in development. This architectural style enhances scalability, facilitates continuous integration and delivery, and allows organizations to respond rapidly to changing business requirements. With a decentralized and independently deployable nature, microservices foster improved fault isolation, easier maintenance, and the ability to leverage diverse technology stacks for different components, making them a preferred choice for building robust, scalable, and resilient software systems in today's dynamic and evolving digital landscape.
