Microservices architecture divides a system into independently deployable services, requiring attention to infrastructure, communication patterns, monitoring, and security. Key components include an API Gateway for unified client access, a Service Registry for dynamic service discovery, and a Service Layer for core business logic. Security is managed via an authorization server, while data storage is tailored to each service. Additional components include distributed caching, asynchronous communication, metrics collection, and log aggregation for enhanced performance and observability.
