Virtuozzo Containers is a popular virtualization platform, that is used to set up virtual servers on physical machines. Every VPS created with it is a standalone software emulation of a server, which means that it has its own OS. The system resources are also fixed, therefore if you obtain a VPS plan with certain CPU, RAM and disk space quotas, they are always available to you and will not be shared with another client on the server. The Virtuozzo Containers software is truly intuitive and convenient to use, so even if you don't have much experience, you will be able to control the entire server using a web-based graphical interface. With a few clicks, you can start/stop/reboot the virtual machine, set firewall rules, set up server-side software programs and do a number of maintenance tasks. You can also track the amount of resources your sites use in real time and all this information will show you whether you should have an upgrade when you expand your world-wide web presence. If needed, you are able to even reset the entire VPS to its original software configuration.
