Content delivery network-based routing of application programming interface requests to cloud service instances

A non-transitory storage medium that stores machine-readable instructions that, when executed by a machine associated with a point of presence of a content delivery network, cause the machine to:

• access an application programming interface (API) request directed to a service;
• process the API request to determine a client identifier associated with the API request, a geographical region associated with the API request and an API call group associated with the API request;
• access location information stored in a global data store based on the client identifier, the geographical region and the API call group, wherein the location information corresponds to an instance of the service;
• and
• route the API request to the instance based on the location information.

An apparatus comprising:

• a hardware processor associated with a point of presence of a content delivery network;
• and
• a memory to store machine-readable instructions that, when executed by the hardware processor, cause the hardware processor to:
• receive an API request directed to a service;
• based on a Uniform Resource Location (URL) represented by first data of the API request, determine a geographical region identifier from a subdomain name of the URL and determine an API call group identifier from a path of the URL;
• based on an authorization bearer token represented by second data of the API request, determine a client identifier;
• determine a location corresponding to an instance of the service based on the geographical region identifier, the API call group identifier and the client identifier;
• and
• forward the API request to the location.
