You are leveraging data stored in a database in one cloud environment with another cloud environment. What statement is true?
It's done by implementing the database in one cloud provider, then creating a "link" to the other cloud providers.
It cannot be done in real time, due to the lag in the system, and hence is best suited for asynchronous background tasks only.
It's similar to linking data in the cloud with data stored on-premise. It requires an application-specific connection between the databases.
You cannot maintain a single source of truth for the data, which complicates synchronization strategies.
