The Process Center is the central repository in IBM Business Process Manager. The Process Center repository contains the artifacts of process applications and allows the sharing of processes and assets across process applications. It also provides governance and lifecycle management capabilities and plays an important role in the deployment of process applications

In the context of deployment, the Process Center is used for the following tasks:

• Management of runtime process servers
  The Process Center maintains a list of online and offline process servers that represent your deployment target. These servers can be classified as test, staging, or production servers.
• Deployment to online process servers
  The Process Center console is used to deploy snapshots of process applications to process servers (test, stage, or production servers).
• Creation of deployment packages for offline-server deployments
  From the Process Center, you can create deployment packages for process application snapshots. Deployment packages are required if you want to deploy to an offline process server.
