Virtuozzo Containers is a well-liked virtualization platform, that's used to set up virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a server, therefore it has its own OS. The resources are also predefined, therefore if you buy a VPS package with certain disk space, RAM and CPU quotas, they're always at your disposal and won't be shared with any other user on the physical server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you do not have a lot of experience, you'll be able to control the entire server using a web-based graphical interface. With just a couple of clicks, you will be able to start/stop/reboot the virtual machine, set firewall rules, install server-side software and perform a variety of maintenance tasks. You can also keep track of what amount of resources your sites use live and all of this info will inform you whether you should have an upgrade when you expand your web presence. When needed, you'll be able to even reset the whole VPS to its original software setup.
