Blue Coat Offers Virtualized WAN Optimizers
WAN optimization without the extra box.
Blue Coat Systems has created virtualized versions of its ProxySG WAN optimizers. Its ProxySG hardware appliance accelerates TCP/IP network, MAPI email, and CIFS file serving protocols, for users at remote offices. According to this report on The Register, with the new ProxySG Virtual Appliance, Blue Coat is taking its WAN optimization software and plunking it atop a virtual machine formatted for VMware's ESX Server hypervisor.
"The devices also provide SSL encryption and decryption and can compress video streams and cache various objects as they are used by applications. The idea is to reduce the amount of bandwidth necessary to give end users working from branch offices over a wide area network, which cuts costs while at the same time improving performance - which reduces frustration.
"With the ProxySG Virtual Appliances, Blue Coat is taking its WAN optimization software and plunking it atop a virtual machine formatted for VMware's ESX Server hypervisor. Since most branch offices already have x64-based servers and ESX Server is the volume leader in server virtualization, this is an easy technology case to make. (The virtual WAN optimization appliances sold by Citrix - which El Reg told you about here and there - run atop XenServer hypervisors, of course, since Citrix wants to promote its own technology)."
