What is glb?

GLB stands for "Global Load Balancer" and is a type of load balancing technology used in computer networks. It is a hardware or software system that distributes incoming network traffic across multiple servers to ensure optimal performance, availability, and scalability.

A GLB system typically sits at the edge of a network, receiving incoming traffic from clients and forwarding it to the most appropriate server based on various criteria such as server availability, geographic location, server load, and type of request. The primary goal of using GLB is to improve website or application performance by distributing workloads across multiple servers instead of overloading a single server.

GLB systems often include health checks, which monitor the status of servers and remove any servers that are down or not responding from the pool. This ensures that only healthy servers are used to handle traffic, thus increasing reliability and reducing downtime.

GLB also allows for traffic routing based on geolocation, which is useful for serving content to users in different regions of the world. GLB systems can direct traffic to servers in data centers closest to the end-user, reducing latency and improving performance.

Overall, GLB technology is widely used in modern computing networks for load balancing large amounts of traffic and improving the availability and performance of websites and applications.
