Adding more machines to the network. Node.js excels here because its lightweight footprint allows running hundreds of micro-instances across a cluster. 2. Why Node.js for Distributed Architectures? Distributed Systems With Node.js Pdf Download

Instead of one massive application, you break functionalities into small, independent services (e.g., UserService, OrderService). Node.js services can communicate over HTTP/REST or gRPC. Event-Driven Architecture (EDA) | Chapter | Title | Core Focus &

Distributed systems have become increasingly popular in recent years due to their ability to scale horizontally and improve overall system performance. Node.js, with its lightweight, flexible, and scalable nature, has emerged as a popular choice for building distributed systems. This paper provided an overview of distributed systems, their architecture, and the role of Node.js in building scalable and efficient distributed systems. We also discussed the benefits and challenges of using Node.js for distributed systems and provided a guide on how to get started with building distributed systems using Node.js.

Services in a distributed system must exchange data reliably. Selecting the right protocol dictates the latency, throughput, and complexity of your architecture. REST and HTTP/2
