Microservices architecture for .NET applications breaks monoliths into independently deployable services. Microsoft's official guide covers Docker containerization, Kubernetes orchestration, DDD for domain modeling, and CQRS patterns to manage complexity, with eShopOnContainers as a reference implementation showing these patterns in practice.

Domain-Driven Design (DDD) structures code around business domains and bounded contexts, while CQRS separates read and write operations for scalability. The Microsoft guide shows how both patterns complement each other in microservices: DDD organizes logic, CQRS optimizes data access and performance.

Docker containers package individual .NET microservices, while Kubernetes orchestrates, scales, and manages those containers in production. The guide explains both technologies and their integration: Docker for containerization, Kubernetes for deployment, service discovery, and resilience.

An API gateway centralizes authentication, rate limiting, and request routing for microservices. Microsoft's guide details security patterns, including OAuth, JWT tokens, and cross-cutting concerns, with code examples showing how to protect containerized .NET services in Kubernetes environments.

Security patterns include inter-service communication encryption, identity and access management, secrets management, and network policies. The guide provides official Microsoft recommendations and implementation patterns for securing microservices across Docker and Kubernetes deployments.

eShopOnContainers is Microsoft's sample microservices implementation demonstrating DDD, CQRS, Docker, and Kubernetes patterns. The guide explains its architecture and code examples, enabling you to extract patterns and apply them to your own containerized .NET microservices projects.
