Abstract

Claims (56)

1 . A system comprising:

a data store configured to store computer-executable instructions; and

one or more processors in communication with the data store, wherein the computer-executable instructions, when executed by the one or more processors, configure the one or more processors to perform operations including:

receiving a task execution request to execute a task on a serverless computing system;

obtaining a criterion for generating a debugging snapshot;

in response to the task execution request, initiating execution of the task in a virtual machine instance of the serverless computing system;

determining, based at least in part on the execution of the task, that the criterion for generating a debugging snapshot has been satisfied;

generating a snapshot of the virtual machine instance as the debugging snapshot;

suspending execution of the task in the virtual machine instance;

causing display of a user interface, the user interface including first controls that enable user inspection of the debugging snapshot and at least one second control requesting resumption of execution of the task;

for at least a threshold period of time, maintaining resources associated with execution of the task in the virtual machine instance;

subsequent to the threshold period of time elapsing:

releasing the virtual machine instance;

obtaining an input to the at least one second control requesting resumption of execution of the task;

configuring a second virtual machine instance according to the snapshot; and

in response to the input being received subsequent to the threshold period of time elapsing, resuming execution of the task in the second virtual machine instance configured according to the snapshot.

2 . The system of claim 1 , wherein the debugging snapshot captures an execution state that includes one or more of memory content, filesystem content, CPU registers, variables, network connections, or configuration information.

3 . The system of claim 1 , wherein the criterion comprises one or more of reaching a specified line of code, throwing an unhandled exception, the task ceasing execution, a variable satisfying a threshold, a specified event occurring, receiving specified input, or the task executing for a threshold duration.

4 . The system of claim 1 , wherein the user interface includes further controls that enable resuming execution of the task by restoring the debugging snapshot.

5 . The system of claim 4 , wherein resuming execution of the task includes restoring at least one network connection established during the execution of the task.

6 . A computer-implemented method comprising:

obtaining one or more criteria for generating a debugging snapshot, the debugging snapshot associated with executing a task on a serverless computing system;

initiating execution of the task in an execution environment of the serverless computing system;

determining, based at least in part on the execution of the task, that the one or more criteria for generating the debugging snapshot have been satisfied;

generating the debugging snapshot, wherein the debugging snapshot includes at least a portion of an execution state of the execution environment;

suspending execution of the task in the execution environment;

causing display of a user interface, the user interface including first controls that enable user inspection of the debugging snapshot and at least one second control requesting resumption of the execution of the task;

for at least a threshold period of time, maintaining resources associated with execution of the task in the execution environment;

subsequent to the threshold period of time elapsing:

releasing the execution environment;

obtaining an input to the at least one second control requesting resumption of execution of the task;

configuring a second execution environment instance according to the debugging snapshot; and

in response to the input being received subsequent to the threshold period of time elapsing, resuming execution of the task in the second execution environment instance configured according to the debugging snapshot.

7 . The computer-implemented method of claim 6 , wherein the one or more criteria are obtained from a request to execute the task on the serverless computing system.

8 . The computer-implemented method of claim 6 , wherein the one or more criteria are obtained from a previous execution of the task on the serverless computing system.

9 . The computer-implemented method of claim 6 , wherein the execution environment comprises a container, and wherein the debugging snapshot comprises a checkpoint of the container.

10 . The computer-implemented method of claim 6 , wherein the one or more criteria include a quantity of debugging snapshots to generate for executions of the task.

11 . The computer-implemented method of claim 6 , wherein the user interface enables interaction with a plurality of debugging snapshots.

12 . The computer-implemented method of claim 11 , wherein the user interface enables comparisons between individual snapshots of the plurality of debugging snapshots.

13 . The computer-implemented method of claim 11 , wherein the user interface identifies a first snapshot of the plurality of debugging snapshots as containing different content than other snapshots of the plurality of debugging snapshots.

14 . The computer-implemented method of claim 6 , wherein the user interface enables specifying a snapshot retention policy.

15 . One or more non-transitory computer-readable media including computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations including:

initiating execution of a task in an execution environment of a serverless computing system;

determining, based at least in part on the execution of the task, that one or more criteria for generating a debugging snapshot have been satisfied;

generating the debugging snapshot, wherein the debugging snapshot includes at least a portion of an execution state of the execution environment;

suspending execution of the task in the execution environment;

causing display of a user interface, the user interface including first controls that that enable user inspection of the debugging snapshot and at least one second control requesting resumption of execution of the task;

for at least a threshold period of time, maintaining resources associated with execution of the task in the execution environment;

subsequent to the threshold period of time elapsing:

releasing the execution environment;

obtaining an input to the at least one second control requesting resumption of execution of the task;

configuring a second execution environment instance according to the debugging snapshot; and

in response to the input being received subsequent to the threshold period of time elapsing, resuming execution of the task in the second execution environment instance configured according to the debugging snapshot.

16 . The one or more non-transitory computer-readable media of claim 15 , wherein the one or more criteria are included in a request to execute the task on the serverless computing system.

17 . The non-transitory computer-readable media of claim 15 , wherein the one or more criteria are obtained from the serverless computing system.

18 . The one or more non-transitory computer-readable media of claim 15 , wherein the execution of the task comprises execution of the task for a specified length of time, wherein the specified length of time comprises a time limit imposed by the serverless computing system.
