Virtuozzo Containers is a widely used virtualization platform, which is used to generate virtual servers on physical machines. Every VPS created with it is a separate software emulation of a website hosting server, which means that it has its own OS. The resources are also preset, so when you acquire a VPS plan with certain CPU, disk space and RAM quotas, they will always be at your disposal and won't be shared with any other client on the physical server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you don't have much experience, you will be able to control the entire server using a web-based graphical interface. With just a couple of clicks, you can start/stop/reboot the virtual machine, manage firewall rules, install server-side software packages and perform many different maintenance tasks. You can also monitor the amount of resources your sites are using in real time and all of this data will tell you whether you'll need an upgrade when you expand your world-wide web presence. When needed, you'll be able to even reset the entire VPS to its original software installation.
