Virtualisation Solutions

Virtualisation SolutionsIT Ambulance provides Virtualisation Solutions based upon Microsoft’s HyperV technology.

The beauty of this particular Virtualisation technology is that it is largely free with any of Microsoft’s Server operating Systems.

So it allows the delivery of very cost effective solutions based upon a widely supported technology.

Virtualisation is the creation of a virtual (computer based) rather than Physical version of something, such as an Operating System, a Server, a storage device or other network location.

If you think about your hard drive on your PC, it is separated into one or more Partitions. C://, D:// E:// etc. A Partition is the division of a hard disk drive to create, effectively, two or more separate hard drives.

Operating system virtualisation is the use of software technology to allow one server to run multiple operating system images at the same time. So one piece of physical hardware server can support multiple Virtual Servers. These can be everything from a machine that supports Windows XP to support the Clocking in Software or Diesel Dispensing management, to separating Exchange Servers and SQL based Databases and applications, or anything in between.

Using Virtualisation, it is simple to move complex, highly critical bespoke applications from out of warranty Hardware to a virtual environment on new hardware without the expensive resource of consultancy from the application vendors.

We have had great success moving Server 2003 based ERP applications across to new hardware  this way.

Virtualisation has now been around several years. It has been heavily adopted and in fact in some IT departments over adopted it. It is now sometimes easier to create a new Virtual Server than to think about where a new application could logically be fitted into the existing infrastructure.

IT Ambulance recently unpicked a department with 48 Virtual Servers, condensing them initially to 12 on 4 Physical Machines. There will be further rationalization moving forward from there, but it shows what your Technicians can do if left to their own devices with an interesting technology.

Another key consideration of Virtualisation is the disconnection of  the Application and Operating System from the Physical hardware. This is a boon when designing Disaster recovery strategy as critical Systems that are virtualised can be moved quickly from one piece of failed hardware straight over to a piece of completely dissimilar hardware, different specification, different manufacturer, with no problems.
