Abstract: Different database deployments, or other data system deployments, may want to communicate with each other without sacrificing security or control. To this end, embodiments of the present disclosure may provide secure message exchange techniques for a source and/or target deployment. Configurable rule sets may be stored in the deployments; the rule sets may define what messages may be communicated between deployments. The deployments may implement a selective filtering scheme in one or more stages based on the rule sets to filter outgoing and/or incoming messages.

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.
