WAN clustering, also called geoclustering or remote clustering, is a network architecture through which multiple servers and other computing resources housed in different geographical locations form what appears to the user to be a single, highly-available network.
The goal of WAN clustering includes maximizing employee productivity by ensuring information assets are available anytime, anywhere. It is a principal architecture IT teams employ as part of disaster recovery/business continuity programs and load balancing. WAN clustering can be used for just about any computing resource, including mainframes, file servers, PCs and software application stacks.
Two core technologies that have enabled the rapid growth of WAN clustering are very rapid wide area network connectivity, and the ability to create and manage a clustered network through a single, virtualized master identity.
Another core capability that is critical to the rapid and secure operation of WAN-clustered network architecture is VPN technology. VPNs ensure information is secure traveling between servers as well as to and from servers and end users’ devices, be they PCs, laptops, tablets or smart devices...Read More >>>
