What is Data Center Virtualization?
From a technical perspective, Datacenter Virtualization is the conversion of the hardware devices in a datacenter into software resources.
Consider your physical data center that typically includes a number of physical servers and other networking and storage devices. These Physical devices are expensive, consume a lot of space and power and generate heat.
Also hardware failures are always potential threat and routine maintenance tasks such as re-deployment and backups are often time-consuming processes require extensive downtime.
Through datacenter virtulaization, you can consolidate your servers into fewer pieces of hardware and effectively manage them using virtualized management platforms.
In a Virtualized environment,each servers operating system and applications are seperated from the underlying hardware and placed on a hypervisor which provides each virtual machine access to the underlying physical resources. This enables multiple virtual machines to access the same hardware.
Need for Data center Virtualization:
The most pressing challenge faced by IT departments in organizations across the world in the infrastructure sprawl that compels IT department to channel 70% of their budget into maintainance leaving scant resources for business building innovation.
Virtualization software solves the problem by enabling several operating systems and applications to run on one physical server or “host”.
Each self-contained virtual machine is isolated from others and uses as much of the host’s computing resources as it requires.
1. Reduces Capital and Operating Costs:
Server Consolidation enables you to get more out of your existing hardware by running multiple virtual machines on a single physical server.
2. Deliver High Application Availability:
Availability and fault tolerance features are integral part of Data Center Virtualization tools and help protect all your virtualized applications.
3. Improve business Continuity:
Virtualization make it easier to survive potential IT disasters. In the event of such a disaster, you can move virtual machines from one server to another in a different location without data loss.
4. Increase Productivity:
Streamlines and automated management tasks allow you to spend less time on maintenance and more time on innovation.
5. Improve Responsiveness:
Virtualization lets your business scale rapidly because you can deploy desktops,applications and servers quickly and flexibly.
