Top Ten important features of server virtualization

Server virtualization has been on the x86 platform for more than 10 years, but in many industries it has been considered a new technology. But for those of us who have adapted to the server virtualization environment, it has become like the elements of air and water, we have long been unwilling to return to the "physical world."

For the IT industry, server virtualization has changed the rules of the game, breaking the boundaries of the physical world and bringing unprecedented efficiencies and new functionality to people. If you're still on the shore, I'll list 10 reasons here to help you dive into the Sea of server virtualization.

10 energy conservation and green technology

Maybe you're not the kind of guy who wears "save whales" T-shirts, no problem. But in 2011 years, who cares about the environment? Migrating physical servers to virtual machines and integrating them can greatly reduce the number of physical servers and reduce the cost of energy and refrigeration per month in the data center.

9 Reduce data center carbon footprint

This is also related to energy conservation, using virtualization to consolidate servers can significantly reduce the data center's carbon footprint, which means much less servers, much less network equipment, and fewer racks, and these also reduce footprint.

8 White-Sent lab environment

After completing the server consolidation, why not put the extra hardware into a lab? With virtualization technology, you can easily build your own lab or test environment to run in an isolated network.

7 Server preparation time is faster

What can be more appealing to a data center administrator than a quick boot and preparation time? The resilience of server virtualization allows you to complete system preparation and deployment in the blink of an hour. You can quickly clone a mirror, a master template, or an existing virtual machine, and it takes only a few minutes to build and run the server.

6 Eliminate hardware vendor lock-in

It's not always bad, but it's always a bit uncomfortable to be tied down by a server provider. Server virtualization can abstract these underlying hardware and replace them with virtual hardware and managers, which can be a much larger choice for users.

5 Improve uptime

Most server virtualization platforms offer a range of advanced features that the physical servers cannot provide to keep business running and improve uptime. These features vary in name on different virtualization platforms, but with less content, such as live migrations, storage migrations, fault tolerance, high availability, and distributed resource management. These features enable you to quickly and easily move a virtual machine from one server to another when a problem occurs, while ensuring business continuity.

4 Improve disaster recovery capability

In disaster recovery, virtualization technology brings enterprise three important functions. The first is the hardware abstraction feature, which is no longer locked in to a vendor and does not need to look for the same hardware configuration environment in disaster recovery, which can save a lot of money when you build a disaster recovery site. The second is to reduce the number of physical servers by consolidating servers, and much less work will be needed in disaster recovery. Third, most enterprise-Class Server virtualization platforms provide software to help automate recovery in the event of a disaster.

3 Isolation Applications

In the physical world, in order to isolate applications, data centers often use a single server application pattern, and the problems that arise are obvious, increasing servers and increasing costs. With the application isolation feature provided by server virtualization, you need a few physical servers to create enough virtual servers to solve this problem.

2 Extending the lifecycle of obsolete applications

Each enterprise will have legacy applications that cannot run on new operating systems and use new hardware, and the IT team will moan and groan as soon as they talk about it. With virtualization, you can encapsulate these old applications into their appropriate environments and extend their lifecycle, and you'll be able to dispose of the Pentium machines in the corner of the engine room.

1 help you walk into the cloud

Oh, yes, cloud! By virtualizing your server, the underlying hardware is abstracted, which can be said to be ready to move to the cloud. The first step may be moving from a virtualized data center to a private cloud, and then with the development of the public cloud and the maturing of related technologies, you will increasingly like the services that the cloud offers.
