A cloud computing platform provides virtual machines on-demand to users. The platform provides a service that enables the user to access and control their virtual machine via an out-of-band channel for administrative purposes. A user invokes this service by authenticating with a control center and receiving a URL that points to a content delivery network (CDN). The user follows the URL to connect to a particular CDN server, per the CDN's request routing architecture. The CDN server applies instructions for handling this cloud compute platform URL, thereby decrypting an encrypted token in the URL to find, e.g., a network locator pointing to the host that is currently hosting the user's virtual machine, as well as an identifier for the user's virtual machine, and authenticators. The CDN server goes forward to the host, connecting to an endpoint which in turn connects to the user's virtual machine to provide the service.
