Programmatic event detection and message generation for requests to execute program code

A system, comprising:

• a computing system comprising one or more hardware computing devices executing specific computer-executable instructions and configured to at least:
• detect an event associated with a first client;
• determine that the detected event is designated to trigger execution of a program code of a second client on a virtual compute system, the virtual compute system comprising computer hardware and configured to execute program codes of clients on behalf of the respective clients on a per-request basis, the second client being different from the first client;
• in response to the determination that the detected event is designated to trigger execution of the program code of the second client, generate an event message comprising at least a client account identifier associated with the second client and event metadata usable to execute the program code on the virtual compute system, the event metadata identifying (i) the program code to be executed on the virtual compute system in response to the detected event and (ii) one or more input parameters to the program code to be used by the program code during the execution of the program code;
• and
• provide the event message to an intermediary message queue system in communication with the virtual compute system.

A computer-implemented method comprising:

• as implemented by one or more computing devices configured with specific executable instructions,
• detecting an event on an event triggering service, the event associated with a first client;
• determining that the detected event is designated to trigger execution of a program code of a second client on a virtual compute system, the virtual compute system comprising computer hardware and configured to execute program codes of clients on behalf of the respective clients on a per-request basis, the second client being different from the first client;
• in response determining that the detected event is designated to trigger execution of the program code of the second client, generating an event message comprising at least a client account identifier associated with the second client and event metadata usable to execute the program code on the virtual compute system, the event metadata identifying (i) the program code to be executed on the virtual compute system in response to the detected event and (ii) one or more input parameters to the program code to be used by the program code during the execution of the program code;
• and
• providing the event message to the virtual compute system.

Non-transitory physical computer storage storing instructions that, when executed by one or more processors, configure the one or more processors to:

• detect an event associated with a first client on an auxiliary service;
• determine that the detected event is designated to trigger execution of a program code of a second client on a virtual compute system, the virtual compute system comprising computer hardware and configured to execute program codes of clients on behalf of the respective clients on a per-request basis, the second client being different from the first client;
• in response the determination that the detected event is designated to trigger execution of the program code of the second client, generate an event message comprising at least a client account identifier associated with the second client and event metadata usable to execute the program code on the virtual compute system, the event metadata identifying (i) the program code to be executed on the virtual compute system in response to the detected event and (ii) one or more input parameters of the program code to be used by the program code during the execution of the program code;
• and
• provide the event message to the virtual compute system.
