A method for interconnecting two or more virtual private networks in a hybrid multi-cloud computing environment. The method may include remapping a first virtual private network to a first Internet Protocol address range that does not overlap with a second Internet Protocol address range of a second virtual private network. The remapping may include assigning, to a first endpoint in the first virtual private network, a first Internet Protocol address that differs from a second Internet Protocol address of a second endpoint in the second virtual private network. Traffic between the first virtual private network, the second virtual private network, and/or a third virtual private network may be routed based at least on the first Internet Protocol address range and the second Internet Protocol address range. Related systems and articles of manufacture, including computer program products, are also provided.

Mapping of internet protocol addresses in a multi-cloud computing environment

In an example embodiment, an instance of a first database and an instance of a first application in a first data center of a managed cloud are replicated to a second data center of the managed cloud. Then state information regarding the first application is stored in a network file system in the first data center. Interactions between a user and the first application are directed to the instance of the first application in the first data center. The state information is then updated based on the interactions, and any changes to the instance of the first database based on the interactions are replicated to the second data center. Then a disaster is detected in the first data center, and all interactions between the user and the first application are redirected to a second instance of the first application in the second data center caused by the replication of the instance of the first application in the first data center.
