# Striim 3.9.4 / 3.9.5 documentation

### Managing deployment groups

Creating deployment groups allows you to control which servers and Forwarding Agents in a Striim cluster will run specific applications and flows. For example, you could use this to ensure that a source is run on the same server as the file or process from which it reads data. The web UI includes Deploy and Undeploy commands in the flow editor.

The default deployment group, which is created automatically, contains all servers and Forwarding Agents in the cluster.

The agent deployment group may be created automatically as discussed in Installing the Striim Forwarding Agent. See also Adapting TQL applications for multi-server deployment.
