Virtuozzo Containers is a popular virtualization platform, that's used to generate virtual servers on physical machines. Every VPS made with it is a separate software emulation of a hosting server, therefore it has its own Operating System. The system resources are also fixed, so when you obtain a VPS plan with certain CPU, RAM and disk space quotas, they are always at your disposal and won't be shared with another customer on the server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you do not have much experience, you will be able to manage the entire server through a web-based graphical interface. With a few clicks, you'll be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software packages and do a variety of maintenance tasks. You can also keep track of what amount of resources your Internet sites use in real time and all of this info will tell you whether you need an upgrade when you expand your online presence. When needed, you will be able to even reset the entire VPS to its original software configuration.
