Abstract: Systems, methods, and computer-readable media for elastic policy scaling in multi-cloud fabrics. A method can involve deploying a cluster of policy agents on a hub virtual private cloud (VPC) that interconnects spoke VPCs in a cloud associated with a multi-cloud fabric, and mapping endpoints in the spoke VPCs to the policy agents. The method can involve distributing groups of policies for the endpoints across the policy agents based on the mapping of endpoints to policy agents, and advertising, by each policy agent to a respective first set of virtual gateways in the spoke VPCs, routes associated with endpoints mapped to the policy agent and preventing the policy agent from advertising routes associated with a second set of virtual gateways in the spoke VPCs. The method can involve applying, via the policy agent, a group of policies on the policy agent to traffic received by the policy agent.

Abstract: Technologies for multi-cloud routing and policy interconnectivity are provided. An example method can include assigning different sets of data plane routers to data plane traffic associated with different address spaces in a cloud site of a multi-cloud fabric to yield a distributed mapping of data plane traffic and data plane routers. The method can further include providing, to an on-premises site in the multi-cloud fabric, routing entries from a control plane router on the cloud site, the routing entries reflecting the distributed mapping and identifying, for each address space, which data plane router handles data plane traffic for that address space; and when a data plane router is deployed at the cloud site, providing, to the on-premises site, updated routing information from the control plane router, the updated routing information identifying the data plane router as a next hop for data plane traffic associated with a respective address space.
