Virtuozzo Containers is a popular virtualization platform, that's used to set up virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a hosting server, therefore it has its own Operating System. The resources are also fixed, thus if you acquire a VPS plan with certain CPU, RAM and disk space quotas, they will always be available to you and won't be shared with some other client on the server. The Virtuozzo Containers software is particularly intuitive and user-friendly, so even if you do not have a lot of experience, you can control your entire server through a web-based graphical interface. With a couple of clicks, you can easily start/stop/reboot the virtual machine, manage firewall rules, set up server-side software applications and do a variety of maintenance tasks. You can also track what amount of resources your websites are using live and this information will tell you whether you should have an upgrade as you expand your online presence. If needed, you will be able to even reset the whole VPS to its original software configuration.
