Virtuozzo Containers is a widespread virtualization platform, which is used to create virtual servers on physical machines. Each VPS created with it is an independent software emulation of a website hosting server, which means that it has its own OS. The resources are also preset, which means that when you get a VPS package with certain CPU, RAM and disk space quotas, they're always available and will not be shared with any other client on the physical server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you do not have a lot of experience, you'll be able to control the whole server through a web-based graphical interface. With a couple of clicks, you'll be able to start/stop/reboot the virtual machine, set firewall rules, install server-side software applications and perform various maintenance tasks. You can also track what amount of system resources your sites are using live and this info will show you whether you should have upgrading when you expand your online presence. If needed, you will be able to even reset the entire VPS to its original software configuration.
