In Business Prospective
1 Cost
The Recent serve shows most of the companies spend their 70-80% of their IT Budget only of maintaining their traditional IT infrastructure, Power and Cooling cost is additional for them so they need huge investment to update latest software's as well as Hardware.
2 Time
For example We have 7 servers like mail server, web server , database server, sap...so each server need particular amount of time to installing , configuration ,maintenance and managing updates , Totally it consumes more time to complete those 7 servers some time it ll take more than a week to complete updates.
3 Man power
A Single admin not able to Configuring and Monitoring all the servers in every time so we need to increase more man power to check the status of all servers in 24*7 time .So we need advanced Technology to over come these barriers and give best solution for Customers.
Virtualization Overview
Now what we are all using the system is based on x86 Hardware,These x86 Hardware's are design to run a single operation system and single application at a time ,here the resources of the systems are vastly underutilized .Virtualization lets you to run multiple operating system and Application in same time. Each Virtual machine shares the hardware from one single physical machine and different virtual machine can run different operating system and application in different environments.
What is Virtualization?
Virtualization is a thin layer of software which directly lies on X86 Hardware or On the Operating system which generate virtual machines and gives the hardware which they needs.Even though shares the hardware from one physical machine it exactly look like a separate machine.
Virtual Machine
Virtual Machine is a isolated software container which has its own operation system and application, Like one physical machine it has its own motherboard,RAM,CPU,Hard disk and Nic card.
