What is Microservices Architecture?

Microservices architecture decomposes a monolithic application into loosely coupled, independently deployable services. Each service owns its data, runs in its own process, and communicates via lightweight protocols (REST, gRPC, or message queues). Benefits include independent scaling, technology flexibility, fault isolation, and faster deployments. Challenges include distributed system complexity, data consistency, and operational overhead. At Attreides, we help teams adopt microservices incrementally using the strangler fig pattern, containerize services with Docker, orchestrate with Kubernetes or AWS ECS, and implement observability with distributed tracing.
