Qu'est-ce que « Border Gateway Protocol, cloud backbone » ?

The Border Gateway Protocol (BGP) is the internet’s routing protocol between autonomous systems: each exchanges reachability information, including the list of autonomous systems a route traverses, and chooses among routes by policy, not by latency. A cloud backbone is a provider’s private network between its regions, which carries traffic between them (peering, replication, its own services) under the provider’s routing.
