Virtualization

Virtualization is an abstraction layer that decouples the physical hardware from the operating system to deliver greater IT resource utilization and flexibility. Capitalhead can help you realize your consolidation and disaster recovery goals.

Virtual InfrastructureVirtualization allows multiple virtual machines, with heterogeneous operating systems to run in isolation, side-by-side on the same physical machine. Each virtual machine has its own set of virtual hardware (e.g., RAM, CPU, NIC, etc.) upon which an operating system and applications are loaded. The operating system sees a consistent, normalized set of hardware regardless of the actual physical hardware components.

Virtual machines are encapsulated into files, making it possible to rapidly save, copy and provision a virtual machine. Full systems (fully configured applications, operating systems, BIOS and virtual hardware) can be moved, within seconds, from one physical server to another for zero-downtime maintenance and continuous workload consolidation.

Virtualization was first introduced in the 1960s to allow partitioning of large, mainframe hardware -a scarce and expensive resource. Over time, minicomputers and PCs provided a more efficient, affordable way to distribute processing power, so by the 1980s, virtualization was no longer widely employed.

In the 1990s, researchers began to see how virtualization could solve some of the problems associated with the proliferation of less expensive hardware, including underutilization, escalating management costs and vulnerability.

We offer a premier standard of consultancy services in all areas of virtualisation. Our approach is based on extensive experience in delivering the very best solutions designed to meet the business and operational requirements of any organisation.

Any engagement with a customer begins with a two way dialogue to assess the needs that are to be addressed by any solution. Only once agreement on the areas to be targeted has been achieved can we begin to offer our impartial advice on the correct methodologies to be followed to achieve the desired result.

Our experience has shown to us and to our customers that the first step of any proposed solution is crucial to ensuring that projects can be relied on to deliver the benefits that were originally sought.

We have formalised this approach to offer two levels of consultative review that provide customers with strategies that are tailored to their individual needs and requirements to ensure that the benefits of virtualisation are actually delivered.

With a unrivalled track record gained over many years in the delivery of virtualisation strategies for a diverse range of customers, we have established ourselves as the premier provider with the skills and knowledge required to meet business demands through the benefits of virtualisation.

Virtualisation is a dynamic and agile response to not only meeting the immediate or known needs and requirements but also one that provides scalability and flexibility that isn’t available via other current technologies.

Virtualisation does however require experienced and knowledgeable professionals to combine the correct combination of technologies to deliver coherent strategies on which businesses can base their information systems.
