Architects use different architecture patterns to design software, just like developers use design patterns. Using the wrong pattern can lead to costly mistakes. It's important for architects to know and understand various architecture patterns. Common patterns include layered, microservices, space-based, event-driven, and microkernel architecture. Real-world examples show how these patterns work and their pros and cons. Requirements and operational aspects influence which pattern to use. Choosing the right architecture pattern is crucial because changing it later is difficult.
