HC9 gives its users the freedom to use any operating system (Windows/Linux) within a cluster. This provides flexibility to manage Windows (IIS) and Linux (Apache) web servers simultaneously through a centralized single interface.
The only pre-requisite to run Linux servers with HC9, is that HC control/master server must have Windows servers installed and have a web-server role. HC9 Linux must be part of HC9 windows panel cluster. All Linux hosting records are stored on windows server database, whereas centralized HC database gives user flexibility to access any/all servers including Windows & Linux running inside the cluster from single interface.
