Virtuozzo Containers is a popular virtualization platform, which is used to make virtual servers on physical machines. Every VPS made with it is an independent software emulation of a server, therefore it has its own Operating System. The resources are also fixed, so if you get a VPS package with certain CPU, disk space and RAM allocations, they are always available to you and will not be shared with another client on the physical server. The Virtuozzo Containers software is particularly intuitive and user-friendly, so even if you don't have much experience, you can manage the entire server with a web-based graphical interface. With only a couple of clicks, you'll be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software programs and do a range of maintenance tasks. You may also track what amount of system resources your sites use in real time and all of this info can inform you if you'll need an upgrade when you expand your web presence. When needed, you can even reset the entire VPS to its original software setup.
