Abstract

A service manages a plurality of virtual machine instances for low latency execution of user codes. The service can provide the capability to execute user code in response to events triggered on various event sources and initiate execution of other control functions to improve the code execution environment in response to detecting errors or unexpected execution results. The service may maintain or communicate with a separate storage area for storing code execution requests that were not successfully processed by the service. Requests stored in such a storage area may subsequently be re-processed by the service.

Claims

1. (canceled)

2. A system, comprising:

one or more processors; and

one or more memories, the one or more memories having stored thereon instructions, which, when executed by the one or more processors, configure the one or more processors to;

receive a request to execute a program code, the request including one or more parameters;

initiate execution of the program code based on the one or more parameters;

prior to completion of the execution in response to the request, modify at least one of the program code or the one or more parameters; and

subsequent to the modification of the at least one of the program code or the one or more parameters, cause the program code to be executed based on the one or more parameters.

3. The system of claim 2, wherein the modification comprises performing a rollback of the program code to an older version.

4. The system of claim 2, wherein the modification comprises performing an update of the program code to a newer version.

5. The system of claim 2, wherein the modification comprises modifying the one or more parameters such that an amount of computing resource allocated for executing the program code is adjusted.

6. The system of claim 2, wherein the instructions, when executed by the one or more processors, further configure the one or more processors to cause the request to be stored in a storage area such that the request can be processed again at a later time.

7. The system of claim 2, wherein the instructions, when executed by the one or more processors, further configure the one or more processors to:

determine that a first amount of computing resource specified by the one or more parameters is insufficient for executing the program code; and

modify the one or more parameters to specify a second amount of computing resource greater than the first amount.

8. The system of claim 2, wherein the instructions, when executed by the one or more processors, further configure the one or more processors to throttle requests to execute the program code such that a rate at which computing resources are used to execute the program code is decreased.

9. The system of claim 2, wherein the instructions, when executed by the one or more processors, further configure the one or more processors to increase a frequency at which one or more metrics are logged.

10. A computer-implemented method comprising:

receiving a request to execute a program code, wherein the program code is associated with one or more parameters;

initiating execution of the program code based on the one or more parameters;

prior to completion of the execution in response to the request, modifying at least one of the program code or the one or more parameters; and

subsequent to the modification of the at least one of the program code or the one or more parameters, executing the program code based on the one or more parameters.

11. The computer-implemented method of claim 10, wherein the modification comprises performing a rollback or an update of the program code to another version.

12. The computer-implemented method of claim 10, wherein the modification comprises modifying the one or more parameters such that an amount of computing resource allocated for executing the program code is adjusted.

13. The computer-implemented method of claim 10, further comprising storing the request in a storage area such that the request can be processed again at a later time.

14. The computer-implemented method of claim 10, further comprising:

determining that a first amount of computing resource specified by the one or more parameters is insufficient for executing the program code; and

modifying the one or more parameters to specify a second amount of computing resource greater than the first amount.

15. The computer-implemented method of claim 10, further comprising throttling requests to execute the program code such that a rate at which computing resources are used to execute the program code is decreased.

16. Non-transitory physical computer storage storing instructions, which, when executed by one or more computing devices, configure the one or more computing devices to:

receive a request to execute a program code, wherein the program code is associated with one or more parameters;

initiate execution of the program code based on the one or more parameters;

prior to completion of the execution in response to the request, modify at least one of the program code or the one or more parameters; and

subsequent to the modification of the at least one of the program code or the one or more parameters, cause the program code to be executed based on the one or more parameters.

17. The non-transitory physical computer storage of claim 16, wherein the modification comprises performing a rollback or an update of the program code to another version.

18. The non-transitory physical computer storage of claim 16, wherein the modification comprises modifying the one or more parameters such that an amount of computing resource allocated for executing the program code is adjusted.

19. The non-transitory physical computer storage of claim 16, wherein the instructions, when executed by the one or more computing devices, further configure the one or more computing devices to cause the request to be stored in a storage area such that the request can be processed again at a later time.

20. The non-transitory physical computer storage of claim 16, wherein the instructions, when executed by the one or more computing devices, further configure the one or more computing devices to:

determine that a first amount of computing resource specified by the one or more parameters is insufficient for executing the program code; and

modifying the one or more parameters to specify a second amount of computing resource greater than the first amount.

21. The non-transitory physical computer storage of claim 16, wherein the instructions, when executed by the one or more computing devices, further configure the one or more computing devices to throttle requests to execute the program code such that a rate at which computing resources are used to execute the program code is decreased.
