Interfaces to manage inter-region connectivity for direct network peerings

A system, comprising:

• a plurality of resource collections of a provider network, including a first resource collection and a second resource collection, wherein the first and second resource collections each comprise compute or storage resources configured to provide compute or storage services to clients of the provider network, and wherein the first resource collection is in a different geographical zone of the provider network than the second resource collection;
• an endpoint router associated with the first resource collection, wherein the endpoint router links the first resource collection to a client network of a client via a dedicated physical network link between the provider network and the client network;
• and
• a connectivity coordinator configured to:
• receive a connectivity request from the client to establish a network path from the client network to the second resource collection;
• and
• perform one or more configuration operations to enable traffic to flow from the client network to the second resource collection, wherein the traffic flows over the dedicated physical network link between the client network and the first resource collection of the provider network and through the provider network to the second resource collection.

A method, comprising:

• presenting a connectivity service to a client of a provider network, wherein the provider network comprises a first resource collection and a second resource collection located in different geographic locations, wherein the first and second resource collections each comprise compute or storage resources configured to provide compute or storage services to the client of the provider network;
• receiving a connectivity request from the client to establish a logically isolated network path to the second resource collection using a dedicated physical link established between an endpoint router associated with the first resource collection and a client network of the client;
• and
• performing a configuration operation to enable traffic to flow from the client network to the second resource collection over the dedicated physical link between the client network and the first resource collection and through the provider network to the second resource collection.

One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors:

• implement a programmatic interface defining connectivity operations available to a client of a provider network, wherein the provider network comprises a plurality of resource collections each comprising compute or storage resources configured to provide compute or storage services to clients of the provider network, and wherein the compute or storage resources of a first resource collection of the provider network are located in a different geographical location than the compute or storage resources of a second resource collection of the provider network;
• receive a connectivity request from the client to establish a logically isolated network path from the client network to the second resource collection;
• and
• perform one or more configuration operations to enable traffic to flow from the client network to the second resource collection over a dedicated physical network link between the client network and the first resource collection of the provider network and through the provider network to the second resource collection.
