Methods, systems and computer program products for data protection across computing infrastructure comprising a plurality of geographically distant computing clusters. The geographically distant computing clusters form a distributed system comprising clusters that are assigned into availability zones. Disaster recovery policies are maintained in each of the availability zones. A first cluster detects a modification of a disaster recovery policy. The modification of the disaster recovery policy that occurred at the first cluster is to be communicated over a wide area network. Synchronization of the disaster recovery policy is accomplished by carrying out a peer-to-peer communication protocol over the wide area network. The peer-to-peer communication protocol comprises issuing a first synchronization request message from a source peer, receiving the first synchronization request message at a remote peer, and issuing a synchronization response message by the remote peer, which in turn is transmitted over the wide area network to the source peer.
