Systems and techniques are provided for the emulation of cloud computing service regions. An emulation system receives an API request including an indication of an endpoint associated with a target region of a cloud computing service from a system in a virtual private cloud. Attributes are extracted from the API request. A manipulated API request is generated from the extracted attributes of the API request. The manipulated API request includes an indication of an endpoint located in a standard region of the cloud computing service. The manipulated API request is transmitted to the endpoint located in the standard region of the cloud computing service.
