A system, comprising: a data center including a resource collection designated to respond to service requests received from a client; a plurality of endpoint routers linked to the data center by one or more private network paths; and a connectivity coordinator; wherein the connectivity coordinator is operable to: implement an interface defining connectivity operations available to the client; receive a connectivity request from the client for dedicated connectivity to the resource collection, wherein the connectivity request is formatted in accordance with the interface; and in response to the connectivity request, select a target endpoint router of the plurality of endpoint routers, wherein the target endpoint router is configurable to provide a route over a private network path of the one or more private network paths in accordance with the connectivity request; generate a reply comprising configuration instructions for a physical network link to be established to the target endpoint router to provide at least a portion of the dedicated connectivity; and transmit the reply to the client; and wherein the connectivity coordinator is further operable to: receive an isolation request from the client to establish a logically isolated network path to the resource collection via the physical link; implement a network isolation mechanism to establish the logically isolated network path over the physical network link in accordance with the isolation request; and send a confirmation message to the client indicating that the requested logically isolated network path has been established, wherein the confirmation message comprises one or more from the group comprising: physical connection confirmation details, logical connection confirmation details, connection identifier and support information. a data center including a resource collection designated to respond to service requests received from a client;
