Virtuozzo Containers is a popular virtualization platform, which is used to make virtual servers on physical machines. Each VPS made with it is a separate software emulation of a website hosting server, which means that it has its own OS. The resources are also fixed, so when you order a VPS plan with certain CPU, disk space and RAM allocations, they're always available to you and will not be shared with any other customer on the physical server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you don't have a lot of experience, you will be able to control the entire server with a web-based graphical interface. With just a couple of clicks, you'll be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software applications and perform a number of maintenance tasks. You may also track the amount of system resources your sites are using in real time and all of this data will show you if you'll need an upgrade when you expand your world-wide web presence. If needed, you can even reset the whole VPS to its original software installation.
