Virtuozzo Containers is a popular virtualization platform, which is used to set up virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a website hosting server, therefore it has its own Operating System. The resources are also fixed, therefore when you purchase a VPS plan with certain CPU, RAM and disk space quotas, they'll always be available to you and won't be shared with some other user on the physical server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you do not have a lot of experience, you'll be able to control the entire server through a web-based graphical interface. With only a couple of clicks, you can easily start/stop/reboot the virtual machine, manage firewall rules, set up server-side software programs and perform a range of maintenance tasks. You can also monitor what amount of resources your websites are using live and all this information will tell you if you will need upgrading when you expand your online presence. If needed, you're able to even reset the whole VPS to its original software installation.
