系统设计是定义软件系统的架构、组件和交互的过程,以满足需求——特别是可扩展性、可靠性和性能。它涉及各个部分如何结合在一起来构建大规模工作的系统。
系统设计涵盖的内容
text
System design = the high-level structure of a system:
→ COMPONENTS → services, databases, caches, queues, load balancers, etc.
→ how they INTERACT → data flow, communication, APIs
→ meeting REQUIREMENTS → functional (what it does) + non-functional (scale, speed,
reliability, availability)
→ about the BIG PICTURE / architecture, not individual code
