From one file server to a server farm replicated across Australia for Disaster Recovery purposes – the cloud doesn’t have to be a black box that is out of sight and no-one knows about.We have solutions that are either Client Managed or Fully Managed by ourselves.Virtual computing has dramatically transformed the way that IT departments and organizations work. Instead of an organization requiring one server per resource-hungry application or department, they can now have as many servers as the physical hardware resources will allow.Although virtual computing has been in use in mainframe computers since the 1960’s; it has until the late 1990’s been a specialised technology. According to market research company IDC, a typical x86 processor server will achieve a utilisation rate of only 10% to 15% total capacity. Because of this a host server can host many virtual servers concurrently without any real performance loss. Each virtual machine contains its own complete Operating System and behaves just as a normal machine would.Virtualisation works by the Virtualised Operating system inserting a layer of software directly onto the physical host hardware (or Host Operating system). The layer installed contains a Virtual Machine console (Hypervisor) that allocates hardware resources both transparently and dynamically to the virtual machines created on it. By doing this multiple Operating systems can run concurrently on a single host, regardless of if it is a single or Multi CPU host. Because the virtual host has access to all the hardware resources it would normally require it is totally compatible with all x86 standard Operating systems, applications, utilities and device drivers. Each computer can have a different configuration and each is independent of each other.Virtualized computing now enables organizations to easily utilize the full potential of the infrastructure they lease from their host or own.Virtualised computing offers:
