Most of the business today are choosing virtualization for Server consolidation, however along with that they get a lot more benefits:
- Reduce power and space requirement in data centres
- Fast application and service provisioning
- Improved manageability
- Business continuity
This clearly explains that the Businesses are focused to do server consolidation and reduction of power and space requirement which is the driving factors even today.
The types of virtualization do we currently have ? as discussed this on my previous post, I am going to compare them today.
According to surveys taken recently we have the following stats.
This clearly explains us that most of the Virtualization technologies are been used today, however still the most popular one is Server virtualization.

One of the way which has become most popular today is consolidating IT infrastructure.

So, most of the companys are looking into different types of virtualizations. They are 3 types of virtualizations which are avalable today.

I have a question today?
How fussy are you to which Wi-Fi signal you connect? i.e., connecting to an open or a secure Wi-Fi connection.
