Many businesses are turning to a relatively new type of IT infrastructure – virtual desktop infrastructure (VDI). Desktop virtualisation is a relatively recent concept, whereby multiple people, using multiple PCs, can access desktop software, controlled from one main server or data centre.
Why Do People Choose VDI?
There are a number of reasons why a business would choose to do this. For example, if a company decided to upgrade the operating systems for every computer within the organisation, this could be extremely expensive and time consuming. This would mean either upgrading each individual PC or buying completely new hardware. With virtual desktops, only the main server or ‘image’ would need to be updated, and then everyone connected to that image would be running exactly the same system.
The Benefits
- Each user connected to the main image will have exactly the same operating system and applications. This reduces the amount of time required to individually install applications on each PC. This could also reduce costs.
- By updating the main image with the latest security updates, you can be sure that every attached PC will also be protected.
- As there is only one main system, if a problem arises, only one system will have to be analysed and fixed, as apposed to analysing a number of different computers.
- A VDI allows you to support a number of computers or mobile devices anywhere in the world from one main server or data centre. This means you don’t have to have all of your systems in one small area. You can even work remotely if necessary. Plus, you’ll have high bandwidth networking and high performance storage.
The Disadvantages
- If an individual requires different applications from the other users, they will require a completely different image, without changing the applications for other users.
- A substantial initial outlay is required for the main server hardware, storage and network infrastructure. This might no be feasible for some smaller businesses.
- Administrators, savvy to the limitations, problem solving and installation of VDIs will either have to be brought in or existing IT staff given the relevant training.
- If a problem occurs, this will generally affect all users, rather than being able to isolate problems if operating systems run off individual PCs.
For many businesses, opting for a VDI seems like a great option – and with good reason. VDIs allow you to streamline your whole IT infrastructure and essentially make your business more profitable.
