A group of services that you share with Integration Cloud is called an application. Applications are created on the on-premise Integration Server and uploaded to the Integration Cloud. Integration Cloud can execute any service hosted by an on-premise Integration Server. When you share services in an application, you are sharing the metadata for the service. For Integration Server services, the metadata you share is the service name, service signature, display name, and service comments. Users of Integration Cloud can then create integrations that invoke services defined in the applications.

When Integration Cloud executes a service, the on-premise Integration Server returns all the results to the Integration Cloud. You can batch the results to limit the number of results returned to the Integration Cloud. For more information, see the Batch Data field in Defining Applications.

After you create applications, you upload them to Integration Cloud. If the application changes on the on-premise Integration Server, you must upload the application again for the changes to be replicated to Integration Cloud.

When you upload applications to the Integration Cloud server, you associate one or more accounts that the application can use to access services on the on-premise Integration Server. If the account associated with an application changes, you can upload the account to the Integration Cloud server without having to upload the application. For more information about uploading accounts, see Uploading Accounts to Integration Cloud.
