Virtuozzo Containers is a popular virtualization platform, that is used to generate virtual servers on physical machines. Every VPS created with it is an independent software emulation of a server, therefore it has its own OS. The resources are also predefined, so when you obtain a VPS plan with certain CPU, RAM and disk space quotas, they will always be readily available and will not be shared with any other client on the server. The Virtuozzo Containers software is truly intuitive and easy to use, so even if you don't have a lot of experience, you can control your entire server using a web-based graphical interface. With a few clicks, you can easily start/stop/reboot your virtual machine, manage firewall rules, install server-side software packages and do numerous maintenance tasks. You may also watch the amount of resources your sites are using live and this data can inform you whether you should have an upgrade as you expand your web presence. If needed, you'll be able to even reset the entire VPS to its original software setup.
