Virtuozzo Containers is a popular virtualization platform, that's used to make virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a server, therefore it has its own Operating System. The system resources are also predefined, therefore when you obtain a VPS package with certain disk space, RAM and CPU quotas, they are always readily available and will not be shared with another client on the server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you don't have much experience, you can control the whole server through a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software applications and perform a range of maintenance tasks. You may also watch what amount of system resources your web sites are using in real time and all of this information will tell you whether you need upgrading while you expand your web presence. When needed, you can even reset the whole VPS to its original software installation.
