What is microservices-based architecture?

Microservices-based architecture is an architectural style that structures an application as a collection of loosely coupled, independently deployable services, modeled around a business domain. Each microservice is a small, autonomous unit that performs a specific function. They communicate with each other through well-defined APIs. Common uses include building complex, scalable, and resilient applications by breaking them down into manageable components, allowing for independent development, deployment, and scaling of individual services.
