Moving to a virtualised environment can reduce your costs, make your business services more agile and give you faster access to resources when you need them. But virtualisation is not for everyone.

Here are 5 reasons to virtualise and 2 reasons not to virtualise:

5 Reasons to Virtualise

  1. Reduced total cost of ownership

    In a virtualised (IaaS) environment you are no longer paying for hardware upfront so your capital expenditure costs are immediately reduced. Additionally, when you virtualise you reduce power draw and cooling requirements in your datacentre. In short, you need fewer resources to run your servers and this means lower costs.

  2. Flexibility

    Virtual environments give you the capability to run multiple operating systems on the same hardware which means you can extend the life of legacy applications without maintaining ageing hardware.

  3. Continuity

    So long as you have the right backup hardware technology you can recover from a disaster in a fraction of the time thanks to Virtual Machine snapshots. If an instance fails you simply kill it and load the latest “safe” snapshot.

    Automation options are available and there are advanced options that allow you to redeploy a server on another host machine without sacrificing downtime. Development and test environments can be cloned identically from live environments at the push of a button, allowing you to test without buying extra hardware or interfering with production.

  4. Scaling

    Virtualisation makes it quick and easy to scale your resources up or down. For example, you can increase the processing power and memory available to an individual server simply by allocating more resources to it. There's no need to physically add extra RAM or CPU components, as you would with a physical server. This means your business can respond in real time to operational needs and if your Cloud infrastructure is capable of “spawning new instances” to cope with demand then you only pay for the processing power and bandwidth that you actually need.

  5. Automation

    Provisioning a new server, automating failover and scaling resources is very simple when you use the latest virtualisation control panels. The majority of maintenance tasks can be managed through the console and set up to run by themselves, across any number of instances.

2 reasons NOT to virtualise

  1. You are not ready for it

    If you run a small business or a relatively simple server environment then you may not need to virtualise. Server virtualisation can save you money, but to do it properly will cost you money, too. There is no point going in to a virtualisation project if you can't pay for the tools and management systems required to support the technology.

  2. Your licenses don't allow it.

    Some software licenses simply don't allow them to be run on virtual machines. You don't want to be doing anything that breaches your software license agreement so be sure to check your entitlements before you virtualise.

The reasons which have given here can be true because virtualising the server is important to know that how the server is working. <a href=""> Dell error code 2000-0142 </a> is an example of the server failure.
