Client-premise resource control via provider-defined interfaces

A method, comprising:

• performing, by one or more computing devices:
• implementing a first set of programmatic interfaces enabling clients to request control operations associated with resources of one or more network-accessible services of a provider network;
• implementing a second set of programmatic interfaces enabling a particular client to submit a registration request, wherein the registration request indicates one or more resources located at a data center external to the provider network as candidate targets for a category of control operation requests issued via the first set of programmatic interfaces, wherein the category of control operation requests pertain to a particular network-accessible service of the one or more network-accessible services;
• receiving a particular registration request via a programmatic interface of the second set of programmatic interfaces, indicating a particular resource of the one or more resources located at the data center external to the provider network;
• establishing a network connection between the particular resource and an administrative resource located within a data center of the provider network;
• and
• in response to a particular control operation request of the category of control operation requests received via a programmatic interface of the first set, transmitting a control command from the administrative resource to the particular resource via the network connection.

A non-transitory computer-accessible storage medium storing program instructions that when executed on one or more processors:

• implement a first set of programmatic interfaces enabling a client to submit a registration request, wherein the registration request indicates one or more resources located at a data center external to a provider network as candidate targets for a category of control operation requests issued via a different set of programmatic interfaces associated with a network-accessible service of the provider network;
• establish a network connection between a particular resource indicated in a particular registration request, and an administrative resource located within a data center of the provider network;
• and
• in response to a particular control operation request of the category of control operation requests received via a programmatic interface of the different set, transmit a control command from the administrative resource to the particular resource via the network connection.
