Server Virtualisation Technology and Machine Software

A Virtual Machine (VM) is software that imitates hardware and the end user can use that machine like the real physical one. You can have multiple VMs running on one physical machine allowing many users to use the VMs with only on physical machine actually being used. Because VMs are actually imitating hardware of real machines you can install a wide range of operating systems and because each VM is separate to each other you can install for example Linux on one machine and Windows on another without the two conflicting with each other.

VMs have some downsides as well for example the more VMs you have the more threads you are going to need on the CPU(s) as well as more RAM and Hard Drive space.

1: Thin Clients: If you have lots of users doing simple not very intensive tasks such as word processing or browsing the internet then you can get just one fairly powerful machine instead of getting everyone their own PC. If everyone’s PC is virtualised on one machine then you only have to maintain that one machine instead of the 10s – 100s of PCs around the building.

2: Virtual Servers: Turn one server into many by creating multiple virtual servers. This can be useful if you have multiple departments or business that all need their own server instead of buying multiple machines and installing them you can buy just one machine.

3: Using unused resources: If you have a server with spare resources that aren’t going to be used then you can turn them into either a few thin clients or if you planning to get a second server to serve some other purpose then you can use the spare resources on hand and create a virtual server.

4: Legacy: Because you can install whatever operating system you like on a VM if you have older software which you need to use you can install an older operating system to run it.

5: It’s possible to move VMs even when they’re in use making the platform really easy to upgrade. Down time if also significantly reduced if something does go wrong because there’s a lot less hardware meaning a lot less points of failure.

Platforms – VMware and Hyper-V

VMware and Hyper-V are two popular products which you’ll find running in most datacentres and servers that run VMs. There are many others but VMware and Hyper-V have become very popular especially Hyper-V, only coming out in 2008 with Windows Server 2008 it has been improved upon over the years. VMware was released in 1998 and is by far the most popular and is what a lot of professionals prefer as there VM software.

Hyper-V is popular with organisations due to its licencing. Being a Microsoft product most companies would already have a licenced purchased to run it and numerous VMs. It also performs roughly the same as VMware with many of VMware features including many of its own making Hyper-V one of the first choices for businesses and organisation wanting to keep prices down while maximising current resources.

Virtualisation is also possible on the cloud making accessing your IT resources where ever you are which is a big plus for businesses on the move.

Key areas you want when you’re running and managing VMs and the systems that run on are;

  • Scalability, Performance & Density
  • Secure Multitenancy
  • Flexible Infrastructure
  • High Availability & Resiliency
