In Virtual Private Servers (VPS), there are hypervisors that offer bare-metal or operating system level virtualization for partitioning the hardware so that the web server resources are used efficiently in a data center.
“Bare-metal” or Type-1 hypervisors are considered for offering improved data isolation for security in file storage and allow to run any type of Linux, Windows, BSD, etc. on the operating system. Type-2 or “hosted” hypervisors copy virtualization at the OS kernel level and are used with several managed VPS or cloud hosting plans.
You will find plenty of open source Linux virtualization platforms based on KVM, while Microsoft has Hyper-V with Windows cloud servers, Citrix maintains the Xen server framework, and VMware has a different hypervisor frameworks such as ESXi. With the help of hypervisors, it becomes easy to manage multiple web servers independently on shared hardware each with file storage, isolated databases, and I/O request processing.… Read More
