Abstract: A network device communication system can configure network devices (e.g., a primary and secondary database) to send and receive sequences messages, such as replication data, over a channel comprising a plurality of private network nodes. The messages can be generated and encrypted using one or more key pairs and changing wrapping replication keys to send and receive the messages between different types of database deployments.

Abstract: A networked device communication system can configure network devices (e.g., a primary and secondary database) to send and receive sequences of messages, such as replicated data, using one or more keypairs and wrapping keys. The sequences of messages can include an initial set of messages that are encrypted by a wrapping key, and further include another set of messages that are encrypted by a replaced staggered key. The sequence of messages can be configured to be decrypted without exporting keys of hardware security modules.

Abstract: Systems, methods, and devices for transitioning a client connection for a database from a first deployment of the database to a second deployment of the database. A method includes maintaining the client connection between a client and the first deployment such that database traffic occurs at the first deployment. The method includes generating a unique identification that references a first connection object of the first deployment and a second connection object of a second deployment. The method includes receiving a notification that the first deployment is unavailable and providing an external connection group unique identification to the second deployment for the second deployment to determine whether the client should be connected to the second deployment. The method includes receiving a uniform resource locator from the second deployment if the client should be connected to the second deployment.
