BGP nell'underlay multi-cloud: resilienza e simmetria tra on-prem e public cloud#

Carlo Pio Luigi Ciciriello

• Why: Directly the PM's cloud-native networking and DC/WAN-interconnect territory: BGP design for hybrid underlays, where resilience and return-path symmetry are the genuinely hard parts.
• What: A BGP underlay design spanning on-prem DCs and public clouds, targeting failover resilience and traffic symmetry between the two. (title only)
• How: Expect session/policy design and path selection across dedicated cloud interconnects to keep flows symmetric on both failover and normal operation — the classic pitfall this class of talk addresses.
• Where applicable: Broadly applicable to any hybrid/multi-cloud design using dedicated interconnects (Direct Connect/ExpressRoute-style), operator or enterprise.
