Which scenario best describes a cloud-to-ground integration use case?

In the context of cloud-to-ground integration, the scenario that best aligns with this definition involves pushing data from Salesforce to an on-premise solution. This type of integration typically signifies that data is being transferred from a cloud-based service (in this case, Salesforce) to a local or on-premise system.

This integration model is crucial for organizations that maintain both cloud services and local infrastructure, allowing them to synchronize data, ensure that on-premise applications have up-to-date information, and facilitate processes that depend on data housed both in the cloud and on local servers.

Other scenarios listed do not represent cloud-to-ground integration as clearly. For instance, pushing data from an on-premise solution to Salesforce indicates a reverse flow, where on-premise data is moved to the cloud, which does not exemplify the "ground" aspect in this type of integration. Similarly, pulling data from Salesforce to an external cloud and extracting data from a local database to Salesforce also don't fit the definition of transferring data from a cloud environment to a ground environment.
