Rate limiting in a decentralized control plane of a computing system

A non-transitory computer readable medium comprising instructions, which when executed in a computer system, causes the computer system to carry out a method of processing a request for a service of a control plane in a computer system, comprising:

• receiving the request, from a client, at a service host process executing on a software platform of the computer system;
• generating an operation object in the service host process that encapsulates a request/response pattern started by the request, the operation object including a plurality of fields that store a context for the request/response pattern within the service host process;
• determining a key based on the context stored by the plurality of fields;
• obtaining a rate limit associated with the key;
• and
• permitting or denying the request for the service based on whether a rate of requests targeting the service exceeds the rate limit.

A computer system, comprising:

• a hardware platform having a central processing unit (CPU), memory, and storage;
• a software platform executing on the hardware platform, the software platform includes a service host process of a control plane, the service host process executable by the CPU to:
• receive a request for a service, from a client, at the service host process;
• generate an operation object in the service host process that encapsulates a request/response pattern started by the request, the operation object including a plurality of fields that store a context for the request/response pattern within the service host process;
• determine a key based on the context stored by the plurality of fields;
• obtain a rate limit associated with the key;
• and
• permit or deny the request for the service based on whether a rate of requests targeting the service exceeds the rate limit.
