Microservices are an architectural approach where applications are built as a collection of small, independent services that communicate over well-defined APIs. Each service is responsible for a specific business capability and can be developed, deployed, and scaled independently.
Key differences from monolithic architecture:
Deployment: Microservices can be deployed independently vs. monoliths deployed as single unit
Technology stack: Each microservice can use different technologies vs. monoliths using single stack
Scaling: Individual services can be scaled vs. scaling entire application
Team structure: Small teams can own services vs. large teams working on single codebase
Failure isolation: Failure in one service doesn't bring down entire system
Example: An e-commerce platform might have separate services for user management, product catalog, payment processing, and order management, each deployable independently.
