Building a Scalable Load Balancer with Node.js and Express Load balancing is a critical component of any scalable web application. It helps distribute incoming client requests evenly across multiple backend servers, optimizing resource utilization and ensuring high availability. In this comprehensive tutorial, we will build a highly flexible load balancer using Node.js and Express that can handle multiple heterogeneous backend servers. Overview Here are the core features we will implement in our load balancer: We will use a modular design pattern to make it easy to modify or extend components later. Our load balancer will run as a standalone Node.js […]
