Virtuozzo Containers is a widespread virtualization platform, that's used to generate virtual servers on physical machines. Every VPS made with it is a separate software emulation of a website hosting server, so it has its own Operating System. The resources are also preset, thus when you purchase a VPS plan with certain CPU, RAM and disk space quotas, they will always be available to you and will not be shared with some other customer 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'll be able to manage your entire server through a web-based graphical interface. With only a few clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, install server-side software programs and perform a variety of maintenance tasks. You can also watch the amount of system resources your websites are using live and all of this info will tell you whether you should have an upgrade when you expand your web presence. If needed, you'll be able to even reset the entire VPS to its original software configuration.
