FlexiScale

FlexiScale is a <a href="/facts/Utility_computing/VoIk5vf3">utility computing</a> platform launched by XCalibre Communications in the summer of 2007, and subsequently acquired by Flexiant. Launched shortly after <a href="/facts/Amazon_Elastic_Compute_Cloud/2EMwnvlS">Amazon's EC2 service</a>, it was Europe's first and the world's second <a href="/facts/Cloud_computing/guhg0FGV">cloud computing</a> platform. Users are able to create, start, and stop <a href="/facts/Server_(computing)/dEaYFD7r">servers</a> as they require allowing rapid deployment where needed. Both <a href="/facts/Windows/bwhAhuSL">Windows</a> and <a href="/facts/Linux/9FvCKSTq">Linux</a> are supported on the FlexiScale platform.
FlexiScale uses the <a href="/facts/Open_source/7X9rCdz4">open source</a> <a href="/facts/Xen/U5fq6ESl">Xen</a> <a href="/facts/Hypervisor/3gX9fKlH">hypervisor</a>. Backend storage comes from a highly redundant <a href="/facts/Storage_area_network/e7bmhrmB">SAN</a>, although the level of redundancy was called into question in August 2008, with more than 2 days of downtime resulting from an engineer mistake. The storage system previously consisted of a dual head <a href="/facts/NetApp_filer/6Te4WeYs">NetApp storage array</a> with the disk shelves connected to both heads. This was replaced with the launch of FlexiScale 2.0 in June 2010 with an "Amber Road" based storage solution from <a href="/facts/Sun_Microsystems/VJ9EzEFd">Sun Microsystems</a>.
There have been a few revisions of the FlexiScale platform, from publicly available information the first version was based on the <a href="/facts/Virtual_iron/DJbLYmY0">Virtual Iron</a> <a href="/facts/Virtual_machine/BLevU3sx">VM</a> management software. The second revision (called FlexiScale v1.5) of the platform was based on a in-house developed VM control system, now known as Extility. The most recent release (called FlexiScale v2.0) contributed an extensively revised User Interface.
