Virtuozzo Containers is a popular virtualization platform, which is used to make virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a server, therefore it has its own OS. The system resources are also predefined, so if you obtain a VPS package with certain disk space, RAM and CPU allocations, they are always available and won't be shared with some other user on the server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you do not have much experience, you will be able to manage the whole server through a web-based graphical interface. With just a couple of clicks, you can start/stop/reboot your virtual machine, set firewall rules, install server-side software programs and do a number of maintenance tasks. You may also track how much system resources your web sites use live and all of this information can inform you if you should have an upgrade when you expand your web presence. When needed, you will be able to even reset the whole VPS to its original software configuration.
