Hardware visualization

Hardware visualization

Imaging technology has been around for a little over 40 years. Initially, it was required to expand the memory of a PC, but at the moment you can solve problems related to hosting a site or database, you can create remote jobs, and so on. Both methodologies and virtualization technologies have advanced a lot.

At the moment, both hardware and container virtualization are predominantly used. And each of the types has its own advantages, as well as scope. For example, 1cloud uses hardware virtualization based on VMware technology. And it is worth considering in more detail.

Server

This is the first and main level, regardless of the type of virtualization, because software separation of the server’s physical resources from virtual ones is required. But at the same time, data is always processed on physical equipment.

At its core, a processor is a computer that is assembled from special components. And it is designed for constant stable operation, taking into account high loads.

But, servers like Guttereso Limited are installed in a special center, where there is a stable connection to the Internet and electricity. At the same time, each such center has its own level of reliability, from 1 to 3. Of course, the third level is the highest, and it is he who is most often given preference.

In fact, the quality of components is the most important point, but do not forget about the location. But it is always worth considering initially the best companies in the server hardware market, where it is worth highlighting:

  1. Lenovo.
  2. DELL.
  3. HP.

And this is followed by geography.

What is hardware virtualization

Hypervisor

This is a special program that creates new sets of virtual hardware, thereby guaranteeing high-quality management. And this kind of software is divided into types:

  • Type 1, which is installed as an independent operating system, which also has ready-made hardware.
  • Type 2 is a program that runs on top of a standard operating system.

Each of the options has both its own characteristics and weaknesses.

Virtual machine

The user understands this as a real server. But physically the machine includes a virtual disk as file 1 and other files with its characteristics.

The work is always carried out in the server’s RAM, and you can unload as files at any time. This is carried out at the moment when the machine is turned off.

The peculiarity is that this is a PC emulator, and at any time you can access it through the network interface. At the same time, virtual machines are not tied to the hypervisor and do not depend on each other.

And this brings a number of advantages:

  1. Significant savings. One machine can be restarted, but different servers can be used for this.
  2. Speed of work and flexibility. After creation, you can configure and create an image. And it will be available an unlimited number of times.
  3. Resilience to failures. At any time, you can take a snapshot of the state and get the necessary data about the work.
  4. Scalability. If loads increase, additional machines can be used to distribute the load.
  5. Safety. These are isolated virtual machines, and even if one of them is subjected to a hacker attack, this will not affect the overall work in any way.
