You can create one or more connections for a connector at design time to use in integrations. A cloud connection is required for configuring and running a cloud connector service. You must create and enable a cloud connection before you can create cloud connector services. You can also test the connection before you save the configuration of a connection. By default, the Test option is disabled. You need to update the respective connector to enable the option. See the respective provider documents for connection configurations and how to configure connections for a connector. Connection configurations vary for each connector.
