Server Sizing Guide
qTest components (and prerequisites applications) communicate with each other via TCP and HTTP, so they can be installed on different systems, as long as they can connect via specific ports. Files that may need to be shared among services can be supported by a distributed file system like NFS or SMB. In Tricentis qTest production cloud deployment, each application has a dedicated server to ensure the best control, but that may not be necessary for an OnPremises deployment.
Your team size and the applications included in your subscription plan determine the right hardware requirements before installation of qTest. Refer to the following guides for general recommendations regarding server sizes.
