Virtuozzo is the ideal solution for those who wants to run multiple applications, Docker containers or sites inside isolated and secure Linux containers and achive maximum utilization of provisioned resources. Virtuozzo creates multiple Linux containers (otherwise known as VEs or VPSs) on a single physical server or EC2 instance enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files. This is BYOL version. You can buy a license here https://virtuozzo.com/products/#product-virtuozzo
