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 an auxiliary service to provide implicit and automatic rate matching and scaling between events being triggered on the auxiliary service and the corresponding execution of user code on various virtual machine instances. An auxiliary service may be configured as an event triggering service to detect events and generate event messages for execution of the user codes. The service can request, receive, or poll for event messages directly from the auxiliary service or via an intermediary message service. Event messages can be rapidly converted to requests to execute user code on the service. The time from processing the event message to initiating a request to begin code execution is less than a predetermined duration, for example, 100 ms.

Abstract: A system for providing security mechanisms for secure execution of program code is described. The system may be configured to maintain a plurality of virtual machine instances. The system may be further configured to receive a request to execute a program code and allocate computing resources for executing the program code on one of the virtual machine instances. One mechanism involves executing program code according to a user-specified security policy. Another mechanism involves executing program code that may be configured to communicate or interface with an auxiliary service. Another mechanism involves splitting and executing program code in a plurality of portions, where some portions of the program code are executed in association with a first level of trust and some portions of the program code are executed with different levels of trust.

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 an auxillary service to provide implicit and automatic rate matching and scaling between events being triggered on the auxiliary service and the corresponding execution of user code on various virtual machine instances.

Abstract: A service manages a plurality of virtual machine instances for low latency execution of user codes. The plurality of virtual machine instances can be configured based on a predetermined set of configurations. One or more containers may be created within the virtual machine instances. In response to a request to execute user code, the service identifies a pre-configured virtual machine instance suitable for executing the user code. The service can allocate the identified virtual machine instance to the user, create a new container within an instance already allocated to the user, or re-use a container already created for execution of the user code. When the user code has not been activated for a time-out period, the service can invalidate allocation of the virtual machine instance destroy the container. The time from receiving the request to beginning code execution is less than a predetermined duration, for example, 100 ms.

Abstract: A system for providing dynamic code deployment and versioning is provided. The system may be configured to receive a first request to execute a newer program code on a virtual compute system, determine, based on the first request, that the newer program code is a newer version of an older program code loaded onto an existing container on a virtual machine instance on the virtual compute system, initiate a download of the newer program code onto a second container on the same virtual machine instance, and causing the first request to be processed with the older program code in the existing container.

Abstract: A data structure is provided that determines which application elements need to be recompiled in a compiler as a result of a change to other application elements, where the change to the other application elements are related to a change in a Java Class Path. The determined application elements are recompiled along with any application elements that have dependencies on the determined application elements.

Abstract: An Integrated Design Environment (IDE) includes an on-the-fly compiler. The IDE does a first compiler pass that review code for dependencies. In the first compiler pass, the IDE compiles source files, where files having any unresolved types or errors are marked for a second pass recompilation. The IDE does a second compiler pass that does a multithreaded compilation of the code in an order determined using the dependencies. In the second compiler pass, any file that uses the files compiled in the first pass are recompiled. Additionally, any files marked for unresolved types or errors are also recompiled.

Abstract: A method for resolving a type in a programming language to a resolve stage is provided. The method includes determining whether a version at the resolve stage of the type exists. The method further includes, if the version at the resolve stage does not exist, allowing a thread exclusive access to the type, resolving the type from an original resolve stage to the resolve stage, by the thread, by adding resolution information for the resolve stage to the type, and creating the version of the type based on the resolving by creating a copy of the type, where the copy of the type is at the resolve stage. Two or more versions are associated with the type, and the two or more versions are at different resolve stages.

Abstract: A dynamic dependency representation 402 may be iteratively constructed and maintained as resources are changed, including resources that are automatically generated. A type differencing component 404 can be employed to more accurately identify when dependent resources should be analyzed or built. And an ordered task set 406 can be used to order the scheduled analysis or build tasks such that duplicate work is reduced or avoided.
