Abstract: Methods and apparatus for automated multi-party cloud connectivity provisioning are disclosed. A system includes resources of a provider network, and a connectivity coordinator. The coordinator collects network service offering metadata of a plurality of connectivity providers using a first set of programmatic interfaces. In response to a connectivity query specifying connectivity parameters, the coordinator identifies, using at least a portion of the metadata, a collection of one or more connectivity providers of the plurality of connectivity providers capable of providing connectivity between a client network and a provider network endpoint in accordance with the connectivity parameters. In response to a connectivity establishment request, the coordinator initiates, using another programmatic interface, an activation of a network connection between the client network and a selected provider network endpoint.
