    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: Systems and methods are described for transforming a data set within a data source into a series of task calls to an on-demand code execution environment. The environment can utilize pre-initialized virtual machine instances to enable execution of user-specified code in a rapid manner, without delays typically caused by initialization of the virtual machine instances, and are often used to process data in near-real time, as it is created. However, limitations in computing resources may inhibit a user from utilizing an on-demand code execution environment to simultaneously process a large, existing data set. The present application provides a task generation system that can iteratively retrieve data items from an existing data set and generate corresponding task calls to the on-demand computing environment. The calls can be ordered to address dependencies of the data items, such as when a first data item depends on prior processing of a second data item.

    Abstract: A system for providing low-latency compute capacity is provided. The system may be configured to route incoming code execution requests based on user indications to use specific containers running on a plurality of virtual machine instances. The system may be configured to process a code execution request, identify, based on the user indication that a specific container previously used to handle a request of similar type is to be used for handling the code execution request, and cause the code execution request to be handled using the specific container.

    Abstract: Systems and methods are described for managing operating system customization in an on-demand code execution system in a manner that enables efficient execution of code. A user may generate a task on the system by submitting code. The system may determine the operating system functions that the submitted code may invoke when executed on the system, and may determine whether the required functionality can be provided by a customized operating system. The customized operating system may provide some functionality but omit other functionality, and thereby avoid consuming any resources associated with making the omitted functionality available. For example, the system may determine that the user-submitted code does not require filesystem interactions, network interactions, interactions with particular devices, caching, paging, profiling, etc., and may thus provide an operating system that does not include one or more of these services.

    Abstract: Systems and methods are described for conducting static analysis of code invoking network-based services to identify, without requiring execution of the code, security issues that may be introduced due to the invocations of the network-based services. A system is provided that may analyze code to detect both direct invocations of services, as well as indirect invocations caused by the direct invocations. The system can compare permissions information for the code to both directly or indirectly invoked services to identify instances in which the code calls services not permitted by the permissions information. In some instances, the system can traverse a “call graph” of all services invoked by code either directly or indirectly to identify permissions errors through multiple levels of indirection.
