The various embodiments described herein include methods, systems, and devices for invoking an interface for a hybrid cloud. In one aspect, a computing system receives, from an invoker, an interface invocation request for a hybrid cloud, the request including a uniform resource locator address and information of a first target cloud platform. In accordance with the request, the computing system determines an interface of the first target cloud platform, e.g., a type of the first target cloud platform, a region of the interface of the first target cloud platform; and an interface within the region as the interface of the first target cloud platform. Next, the computing system sends the request to the interface of the first target cloud platform and then receives a response from the interface of the first target cloud platform.
