Virtualization competitors

Virtualization is very hot topic in IT industry.Most of the organizations are moving towards Virtualization because it has many advantages.
Virtualization is a technology by which we can use the resources of one machine by installing many operating system on it.we don't need any other hardware for installing different operating system.
We can purchase a state of the art hardware and can use it for multiple Operating Systems and they will perform their services individually.
There are two major types of virtualization one is Bare metal (Directly installed on the hardware ) and other is hosted(installed on conventional Operating System)   
As we know use of gadgets/tablets/laptops is growing so use of internet services is also increasing. ISP (Internet Service providers) need to provide  reliable services to their customers.so for this purpose they need to install a backup for their servers.there is a budget issue in IT industry to purchase state of the art equipment as primary and secondary/backup use.
we can also relate this scenario to different IT organizations that they need to provide internet services,File sharing services,printing services to their staff members.so to avoid the interruption in services they may need to install backup servers.
we can relate these scenarios to many other domains of daily life like educational institutes,Software houses,data centers they also need to install backups for their reliable services.
For this purpose Virtualization was introduced and got an awesome output form the industry.
