Understanding load balancers

In the fast-paced world of modern computing, organizations face ever-increasing demands for high availability, scalability, and optimal performance of their online services and applications. Network load balancers are an integral component of modern network infrastructure, playing a crucial role in managing the distribution of network and application traffic across multiple servers. It’s a solution designed to ensure efficient resource utilization and prevent any single server from being overwhelmed and being a single point of failure:
