Virtuozzo Containers is a widespread virtualization platform, which is used to make 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 fixed, so if you obtain a VPS package with certain CPU, disk space and RAM quotas, they'll always be readily available and will not be shared with another customer on the server. The Virtuozzo Containers software is particularly intuitive and user-friendly, 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 just a few clicks, you can start/stop/reboot your virtual machine, set firewall rules, install server-side software packages and perform plenty of maintenance tasks. You may also track how much system resources your web sites use in real time and all of this data will show you if you will need an upgrade when you expand your web presence. If needed, you're able to even reset the whole VPS to its original software configuration.
