Global server load balancing (GSLB) refers to the intelligent distribution of traffic across server resources located in multiple geographies or Global server load balancing (GSLB) is a method of distributing Internet traffic to a network of servers across the globe, creating a faster and more reliable user experience.
The servers can be on premises in a company’s own data centers, or hosted in a private cloud or the public cloud. The idea is straightforward: the more hands working, the faster the job gets done. With regards to computer networks, load balancing increases overall computing efficiency, minimizes downtime, and raises overall performance and throughput.
As more and more computing is done via the Internet, “load balancing” has taken on a much broader context. Global load balancing is based on the same principle as other methods of server load distribution, but its implementation is not limited to a local network. Instead, the workload is distributed planet-wide instead of across just one data center.
