Load balancing isn't just for websites that expect surges in traffic any more. Companies of all sizes, and in all verticals, find load balancing an effective way to address disaster recovery, scalability, failover and application virtualization needs.

Enterprises are taking a variety of approaches to keep applications online as virtualization puts more apps on fewer servers. While experts in the virtualization field say many firms use high availability software associated with the widely used VMware hypervisor, fault tolerant servers-a throwback to the 1980s-also vie for a role in heavily virtualized environments. This is in large part because they promise an uptime improvement over high availability solutions.
As virtualisation puts more application eggs into fewer server baskets, design principles such as high availability require more attention.
Securing virtualized network resources may seem somewhat exotic on the surface, but the task isn't necessarily all that complicated. It may even have a familiar ring.
Enterprises replacing legacy network infrastructure are increasingly turning to software-defined networks, which can automate an entire network fabric. Having helped hosting companies and academic institutions, a variety of resellers, system integrators and consultancies are ready to bring SDN to the enterprise.
