What Is Virtualisation?

Virtualization was and is still the domain of VMware who is very much viewed as the leader of the pack, closely followed by Microsoft Hype-V and was born from the inefficient use of resources by what we know as modern Servers.  Traditionally an application was installed on one server even though these would only use a fraction of the processing power, memory and disc.  This practice meant that each time a new application was added to an organizations’ catalogue the appropriate hardware needed to be purchased too.  In addition to this the lack of resilience would cost organizations’ thousands more in downtime and maintenance.

Virtualization gave the ability for organizations to run as many applications from one server that the Processor, Memory and Disc would allow in effect reducing hardware costs and introducing the ability to provide resilient IT systems.  So, successful is this paradigm that it has now spread to other areas of infrastructure including Storage and Networking.

This ability to detach the application from the underlying hardware and instead have it running purely as a software layer meant zero downtime.  This also brought with it other benefits which are only just being realized such as the ability to move from on premise or private cloud infrastructure to public and a mix of the two “Hybrid Cloud” at will.  Imagine the implications this had to times when extra infrastructure was required due to accounting, customer service, research and design the list is almost endless.
