Virtualization

Virtualization is a technology that allows you to create virtual versions of computing resources, such as servers, storage, networks, etc. This allows you to use physical resources more efficiently by dividing them between different applications and users. Virtualization allows you to create isolated environments that separate applications from each other and from the operating system, which ensures the security and stability of the system. In addition, virtualization allows you to use resources more efficiently, as you can run multiple virtual machines on a single physical server. The main benefits of virtualization include reduced hardware and energy costs, easier administration and data backup, and increased scalability and flexibility.

Virtualization is a technology that allows you to create virtual versions of computing resources, such as servers, storage, networks, and more. The basic principle is that virtualization software (hypervisor) creates virtual instances of hardware that can be used to run virtual machines (VMs). Each VM runs as a separate computer, with its own operating system and programs.

One of the main features of virtualization is the ability to consolidate resources, which allows for more efficient use of hardware and reduces costs. For example, several virtual machines can run simultaneously on one server, which saves space and energy. Virtualization also provides a high degree of flexibility, as it allows you to easily scale the system, add new virtual machines or change their resources.

Another important feature is the ability to isolate different VMs from each other, which ensures security and stability. Each VM has its own environment, and accidental errors or attacks on one VM do not affect the others. In addition, virtualization makes it easy to back up and restore data, which ensures high system reliability.

To summarize, virtualization is a powerful technology that allows you to efficiently use computer resources, providing flexibility, security, and reliability of the system.
