Middleware Patterns: Message Queues, Proxies, and Buses
Middleware Patterns: Message Queues, Proxies, and Buses Middleware patterns help teams build scalable systems by decoupling components. Three common patterns are message queues, proxies, and buses. Each pattern changes how components communicate, influencing reliability, latency, and failure handling. This article explains what each pattern does, when to use it, and a simple example. Message Queues Message queues let producers send work for later processing. A queue stores tasks until a worker fetches them. This introduces resilience: if a service slows down, tasks pile up rather than blocking the whole flow. It also enables parallel work, since many workers can run at once. ...
