App Host and integration server

If you are using apps in your IBM Security QRadar® SOAR Platform deployment, you need a system to host them. The type of system that you use to host the apps depends on whether the app is a container-based app or an extension-based app.
App Host

An App Host is a Kubernetes-based container deployment environment that hosts container-based apps.

A single system can host multiple App Hosts, where each App Host is paired to a single SOAR organization.

You cannot install the App Host and resilient-circuits on the same system. The App Host must be installed on a dedicated system.

Integration server
Use the integration server to create or download extension-based apps and then deploy them to the SOAR Platform.

Regardless of which type of hosting system that you use, for security and performance reasons,IBM® recommends that you use a dedicated system to host the apps.
