We offer our customers two types of server virtualization to choose from: OpenVZ (operating system level) and KVM (hardware level).
The OpenVZ technology is based on the Linux OS kernel and allows creating and running isolated copies of the operating system on a single physical server – the so-called Virtual Private Servers, VPS or Virtual Environments, VE. This technology is characterized by high performance, ease of use and easy management of the server. The user can also increase the capacity of such a virtual server at any time. In this case, the choice of operating system is possible only from the range of choices (Debian, CentOS, Ubuntu), as the virtual servers of a particular host machine use a common Linux kernel.
KVM (Kernel-based Virtual Machine) is a hardware virtualization technology that allows you to create on a host machine a complete virtual analog of the real physical server. Each such server is allocated its own area of memory and space on the hard disk, its own network card, which increases the overall reliability of the server. In fact, KVM technology allows you to create a completely isolated from the “neighbors” virtual server with its own operating system kernel, which the user can configure and modify to suit his needs with almost no restrictions. It is possible to install any operating system: Linux, FreeBSD, Windows and even your own image. At the same time, changing the server resources is impossible – if your project “grows” from the initially selected tariff, it will need to order a more productive virtual server at the appropriate tariff and transfer all data to it (as in the case of the real dedicated server). The exception is VDS-Force and VDS-Atlant tariffs, where the user can change the number of available processor cores and RAM (hard disk – upon request to the support service).
