Per-execution network bandwidth use monitoring in a serverless code execution system

A computer-implemented method comprising:

• obtaining a request to execute code on a serverless code execution system;
• selecting an execution environment on the serverless code execution system in which to execute the code;
• determining a bandwidth throttle for the execution of the code;
• prior to executing the code within the execution environment, reading an initial state of a network interface of the execution environment, wherein the initial state reflects a volume of data associated with the network interface providing network access to the execution environment at a first time, and modifying the network interface to enforce the bandwidth throttle;
• initiating an execution of the code within the execution environment;
• subsequent to the execution of the code within the execution environment, reading a subsequent state of the network interface of the execution environment, wherein the subsequent state reflects a volume of data associated with the network interface providing network access to the execution environment at a second time, and modifying the network interface to remove the bandwidth throttle;
• and
• transmitting an execution result for the execution of the code, wherein the execution result includes a bandwidth use of the execution environment associated with the execution of the code, the bandwidth use calculated based at least on a difference between the volume of data at the first time and the volume of data at the second time.

One or more non-transitory computer-readable media comprising computer-executable instructions that, when executed by a serverless code execution system, causes the serverless code execution system to:

• obtain a request to execute code on the serverless code execution system;
• select an execution environment on the serverless code execution system in which to execute the code;
• determine a bandwidth throttle for the execution of the code;
• prior to executing the code within the execution environment, read an initial state of a network interface of the execution environment, wherein the initial state reflects a volume of data associated with the network interface providing network access to the execution environment at a first time, and modify the network interface to enforce the bandwidth throttle;
• initiate an execution of the code within the execution environment;
• subsequent to the execution of the code within the execution environment, read a subsequent state of the network interface of the execution environment, wherein the subsequent state reflects a volume of data associated with the network interface providing network access to the execution environment at a second time, and modify the network interface to remove the bandwidth throttle;
• and
• transmit an execution result for the execution of the code, wherein the execution result includes a bandwidth use of the execution environment associated with the execution of the code, the bandwidth use calculated based at least on a difference between the total volume of data at the first time and the total volume of data at the second time.
