What is Virtualization ?

    Virtualization is a model of computing that allows the running of multiple virtual server machines (VMs) on a single physical server. Virtualization is the efficient alternative to the one server, one application model; applications and operating systems typically only use a fraction of the capacity and resources available on a physical server. This leaves the physical server with copious computing power left untapped.

    How does it work?

    With the physical server ready, we (or your experienced IT staff) will install a software layer (known as the hypervisor – a sort of virtual machine manager) on either the host physical server hardware or the host operating system. This software layer will allow us for the management and allocation of the hardware resources – the CPU, RAM, storage, and networking resources – and the setting up of the multiple operating systems, which will each become its own Virtual Machine.

    Tell me more about virtual hosting.

    Virtual servers operate exactly as physical dedicated servers do, and are accompanied with all necessary resources such as CPU, RAM, storage, networking, root/admin access, an operating system, and all other features you require. Virtual servers can also be migrated easily from host physical server to another and can be configured to form a cloud environment with a failover plan, fault tolerance, and all other cloud-equipped functions. End users will be left with a lower hosting cost as a result of the efficient environment of virtual servers. End users can also benefit from the flexibility of virtual servers – the ability to instantly increase or decrease resources, create virtual clusters, and more.

    A quick list of virtualization advantages, please.

    • Reduced data center physical space
    • Energy consumption
    • Lower hardware costs
    • Fewer maintenance staff
    • Higher flexibility
    • Improved business continuity and performance
