Stop Building Monoliths: Orchestrate with Events, Not Servers

One monolithic server handling all traffic is a scaling nightmare. The future is small, ephemeral functions working in concert. But how do you orchestrate them without introducing latency? The Solution: Message Broker / Event Bus Use a Message Broker or Event Bus . This layer doesn't process data. It routes incoming signals to handlers (e.g., Auth , Payment , Logging ). It manages the flow and hands off payloads between them. Why This Works Principle Benefit Loose Coupling Handlers don't depend on each other — change one, break none Single Responsibility If payment fails, you debug the Payment Function. Period. Independent Scaling Traffic spike on auth? Scale only the Auth Handler. Resilient by Design One handler crashes? The bus queues events and retries. Key Takeaway Modular infrastructure is resilient infrastructure. Don't build a server farm; build a flow. Pro Tip: Start with one broker (Kafka, RabbitMQ, or even Redis Streams) and let your handlers evolve independently. Your future
