A group of services that you share with webMethods Cloud is called an application. Applications are created on the on-premise Integration Server and uploaded to webMethods Cloud. webMethods 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 webMethods Cloud can then create integrations that invoke services defined in the applications.

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

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

When you upload applications to the webMethods 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 webMethods Cloud server without having to upload the application. For more information about uploading accounts, see Uploading Accounts to webMethods Cloud .
