Virtuozzo Containers is a well-liked virtualization platform, that's used to make virtual servers on physical machines. Every VPS made with it is a separate software emulation of a server, so it has its own OS. The resources are also preset, so when you get a VPS package with certain disk space, RAM and CPU allocations, they are always readily available and won't be shared with another user on the physical server. The Virtuozzo Containers software is really intuitive and easy to use, so even if you don't have a lot of experience, you'll be able to control the whole server using a web-based graphical interface. With only a couple of clicks, you will be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software and do numerous maintenance tasks. You may also watch how much resources your sites are using in real time and all this information will tell you whether you need an upgrade while you expand your online presence. When needed, you'll be able to even reset the entire VPS to its original software setup.
