Function parallelism in a runtime container of a function-as-a-service (faas) system

A system comprising:

• a memory;
• and
• a processing device operatively coupled to the memory, the processing device to:
• receive a first request to execute a first instance of a function;
• generate a runtime container to execute the first instance of the function, the runtime instance comprising a set of resources allocated to execute the function;
• determine a consumption of the set of resources allocated to the runtime container in view of execution of the first instance of the function;
• and
• in response to receiving a second request to execute a second instance of the function, initiate the second instance of the function within the runtime container in view of the consumption of the set of resources.

A non-transitory computer-readable storage medium including instructions that, when executed by a processing device, cause the processing device to:

• receive a first request to execute a first instance of a function;
• generate a runtime container to execute the first instance of the function, the runtime instance comprising a set of resources allocated to execute the function;
• determine, by the processing device, a consumption of the set of resources allocated to the runtime container in view of execution of the first instance of the function;
• and
• in response to receiving a second request to execute a second instance of the function, initiate the second instance of the function within the runtime container in view of the consumption of the set of resources.
