Virtualization – What is Virtualization? Benefits of server virtualization technology

Let’s chusa.info learn more about Virtualization – What is Virtualization? Benefits of server virtualization technology below!

Even something as simple as partitioning a hard drive is considered server virtualization because you only have one drive but it is partitioned to form two separate hard drives. There are many benefits to an IT organization or business when choosing to implement server virtualization. will share more details for readers to better understand this issue.

Virtualization – What is Virtualization?

In computing, virtualization means creating a virtual version of some resource, such as a server, storage device, network, or even operating system where the framework divides the resource into one or more execution environments .

Devices, applications, and users can interact with the virtual resource as if it were a single truly logical resource. The term virtualization has become part of computer technologies, including:

  • Network virtualization is a method of combining available resources in a network by dividing the available bandwidth into channels, each independent of the others, and each channel can be assigned (or reassigned). for a specific server or device in real time. The main idea of Network virtualization is that virtualization disguises the real complexity of the network by separating it into manageable parts, like a partitioned hard drive, making it easier to manage files.
  • Storage virtualization is the aggregation of physical storage from multiple network storage devices into a single storage device that is managed from a central console. Storage virtualization is commonly used in storage networks (SANs).
  • Server virtualization is the virtualization of server resources (including the number and identity of physical servers, processors, and operating systems) from server users. The goal is for users to avoid having to understand and manage the complex details of server resources.

The main benefits of server virtualization (Server Virtualization)

There are many benefits to an IT organization or business when choosing to implement server virtualization.

1. Energy saving, environmentally friendly (go green)

Moving physical servers into virtual machines and consolidating them into a smaller number of physical servers will help you reduce monthly electricity and cooling costs in the data center.

2. Servers work faster

Server virtualization allows for the ability to scale up or down during system deployment at a time of need. You can quickly clone an existing gold image, master template, or virtual machine to get a server up and running in minutes.

3. Increase uptime

Most server virtualization platforms now offer some advanced features that physical servers don’t, helping to improve business continuity and increase uptime. Although vendor feature names can vary, they are usually the following: live migration, storage migration, fault tolerance, high availability, and distributed resource scheduling.

Technologies that provide rapid recovery from unplanned outages. The ability to move a virtual machine from one host to another quickly and easily is perhaps one of the biggest benefits of virtualization, making it widely used. As technology continues to evolve to the point where long-distance migration can be performed, such as being able to move virtual machines from one data center to another regardless of network latency. .

4. Improved disaster recovery

Virtualization provides an organization with three key components in building a disaster recovery solution.

  • The first is the ability to hardware abstraction. By eliminating the dependency on a specific hardware vendor or server model, a disaster recovery site no longer needs to keep the same hardware to match the production environment and IT can save money by Buy cheaper hardware.
  • Second, by consolidating servers into fewer physical machines in production, an organization can easily create an affordable replication site.
  • Third, most enterprise server virtualization platforms have software that can automatically help with fault tolerance in the event of a disaster. Similar software also provides a way to check disaster recovery failover. You’ll be able to test how your failover plan will work in practice, helping you to better prepare for unexpected disasters in the future.

What about virtualization in the data center?

1. Less heat build-up

Server virtualization will help you use less physical hardware. Uses less physical hardware so less heat is generated. Less heat generated in the data center reduces a wide range of problems caused by high temperatures.

2. Cost reduction

Hardware often accounts for the highest cost in a data center, so reducing the amount of hardware used means you have significantly reduced costs. In addition, you save even more costs by less downtime, easier maintenance, and less power consumption.

3. Easier Backup

Not only can you backup your entire virtual server, you can also backup and snapshot your virtual machines. These virtual machines can be moved from one server to another and redeployed easily and quickly. Snapshots can be taken multiple times a day, ensuring much more up-to-date data. And because triggering a snapshot is even faster than starting the server, downtime is cut dramatically.

4. Easier to move to the cloud

Using a virtual machine brings you closer to a full-blown cloud environment. You can even deploy VMs to and from the data center to create a robust cloud-based infrastructure. In addition to actual virtual machines, virtualization brings you closer to a cloud-based mindset, making the transition easier.
