This article serves as an in-depth guide to building , focusing on microservices, communication patterns, reliability, and observability, essential for architects and senior developers. What are Distributed Systems with Node.js?

Distributed systems offer several benefits, including:

As modern web applications grow in complexity, the limitations of traditional monolithic architectures become apparent. High-traffic systems, real-time data processing, and the need for high availability have pushed developers toward distributed systems. Node.js, with its asynchronous, event-driven model, has emerged as a premier technology for building these scalable and resilient systems.

Do your services require (like WebSockets)?

ObservabilityIn a distributed system, debugging becomes difficult. You need to understand distributed tracing, centralized logging (ELK stack), and monitoring tools like Prometheus and Grafana.
