Dear Readers! Today we will be understanding the concepts of Virtualization, available products & its features...
Virtualization:
It is the technique of splitting a physical resource into as many logical pieces as we want.
Is it applicable only for splitting?
Virtualization is not just restricted to splitting physical resources but also adding them up to make a consolidated single logical resource.
Various virtualization factors:
Server Virtualization
Application Virtualization
Desktop Virtualization
Storage/Network Virtualization
Hypervisor:
It is a firmware/software which is used to create & manage virtual machines on physical hosts/servers.
A hypervisor directly interacts with the physical server/computer & extracts physical resources like CPU, Memory, Network and distribute them among virtual machines.
Types of Hypervisor:
Type 1:
* Directly installs on bare machine
* This is an enterprise class solution, used for large environment
* Most famous examples are: VMware ESXi, Citrix XenServer
Type 2:
* Installs on an OS/platform which is running on a physical machine
* It is used for testing, small environment, POC, etc.
* Most famous examples are: VMware Workstation/Fusion, Oracle VirtualBox
Thats all for this blog now!
