Abstract: An embodiment method creates, at a first data center, a first storage volume for an application that is started at the first data center, communicates with a second data center for creating a second storage volume for the application at the second data center to replicate the first storage volume, and sends information identifying the application to the second data center. The second data center creates the second storage volume, and establishes a mapping between the application and the second storage volume using the information identifying the application, where the second data center identifies the second storage volume for the application using the mapping when the application is migrated from the first data center to the second data center.

Abstract: A computer-implemented method for on-demand data replication in a network architecture includes activating an on-demand program to pair a network-based replication agent with a data source. Compute resources for the replication agent are allocated based on one or more hints received from the data source. The one or more hints are indicative of at least a size of an upcoming data traffic transmission from the data source. Upon receiving data from the data traffic transmission, the replication agent is activated via the on-demand program to replicate the received data using the allocated replication resources. The allocated compute resources are released upon completion of data replication of the received data. The on-demand program is a serverless function configured to activate the replication agent on-demand, upon receiving the data from the data traffic transmission.
