Virtuozzo Containers is a widespread virtualization platform, which is used to make virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a website hosting server, so it has its own OS. The system resources are also preset, therefore if you get a VPS plan with certain disk space, CPU and RAM allocations, they're always available to you and won't be shared with some other client on the physical server. The Virtuozzo Containers software is truly intuitive and convenient to use, so even if you do not have a lot of experience, you will be able to control the entire server through a web-based graphical interface. With just a few clicks, you'll be able to start/stop/reboot the virtual machine, set firewall rules, set up server-side software applications and do various maintenance tasks. You may also track what amount of resources your websites use in real time and all this info will tell you if you should have an upgrade as you expand your online presence. When needed, you will be able to even reset the whole VPS to its original software installation.
