A structured overview of five key software architecture patterns: layered (n-tier), microkernel (plug-in), CQRS, event sourcing, and microservices. Each pattern is explained with its core idea, advantages, disadvantages, and ideal use cases. The post also clarifies the distinction between design patterns (code-level) and architecture patterns (system-level), and offers guidance on how to choose the right pattern based on domain complexity, read/write load, audit requirements, and scaling needs. Patterns can be combined — for example, microservices with some services using CQRS and event sourcing internally.
