Virtuozzo Containers is a widespread virtualization platform, that is used to make virtual servers on physical machines. Every VPS created with it is a standalone software emulation of a website hosting server, therefore it has its own Operating System. The resources are also preset, so if you obtain a VPS package with certain disk space, RAM and CPU allocations, they're always available to you and won't be shared with some other customer on the server. The Virtuozzo Containers software is very intuitive and easy to use, so even if you do not have much experience, you can control the whole server using a web-based graphical interface. With only a few clicks, you will be able to start/stop/reboot your virtual machine, set firewall rules, install server-side software and perform numerous maintenance tasks. You may also track what amount of resources your sites are using in real time and all of this info will tell you if you should have an upgrade when you expand your world-wide web presence. When needed, you can even reset the whole VPS to its original software setup.
