Abstract:
Systems, methods, and computer-readable media for creating service chains for inter-cloud traffic. In some examples, a system receives domain name system (DNS) queries associated with cloud domains and collects DNS information associated the cloud domains. The system spoofs DNS entries defining a subset of IPs for each cloud domain. Based on the spoofed DNS entries, the system creates IP-to-domain mappings associating each cloud domain with a respective IP from the subset of IPs. Based on the IP-to-domain mappings, the system programs different service chains for traffic between a private network and respective cloud domains. The system routes, through the respective service chain, traffic having a source associated with the private network and a destination matching the IP in the respective IP-to-domain mapping.
