Select your OnPremises Systems and Deployment Model for Manager 2026.2

qTest components (and prerequisite 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 the 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.

Supported Systems

Architecture Diagram

Connectivity between components is agnostic to server deployment. qTest components (and prerequisites applications) communicate with each other via TCP and HTTP connection, 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.

Deployment Models
