Api version compatibility and request conversion methods
The patent US12047414B2 outlines a method for handling Application Programming Interface (API) requests within a distributed cloud computing platform. The method involves a first compute server receiving an API request from a client device, which is directed to an origin server. This server, identified as the closest to the client based on anycast IP addressing, determines that the API request is of a version different from that used by the origin server. In response, the server converts the request into the appropriate version and fulfills it, utilizing isolated execution environments that operate concurrently within a single process, rather than traditional containers or virtual machines.
Additionally, the patent describes the process of managing API responses. Upon receiving a response to the converted API request, the server checks if the response corresponds to the new version. If so, it converts this response back to the original version before transmitting it to the client device. The claims also detail mechanisms for identifying API versions through version identifiers, the potential for an API compatibility enabler to facilitate conversions, and the ability to modify request fields during the conversion process. This innovative approach aims to enhance compatibility and efficiency in API interactions across different versions within cloud computing environments.
