Abstract: A computer-implemented method for processing serverless functions includes mapping a received event to an event state of a plurality of event states in a function graph according to a mapping rule, the function graph including one or more actions for the event state. A data package of a previous event state of the plurality of event states is filtered to generate a filtered data package, using a payload filter associated with the event state. The actions of the event state are executed, where the one or more actions satisfy the mapping rule. A modified data package is sent to a computer system to trigger executing one or more serverless functions associated with the executed one or more actions. The modified data package is based on a data package of the event and the filtered data package. One or more responses are received based on execution of the serverless functions.

Abstract: Operation of an autonomous vehicle is modified based on the driving style preferences of a passenger. A machine learning module for a motion planner of the autonomous vehicle accepts input relating to driving style of the autonomous vehicle including data representing autonomous vehicle speed, acceleration, braking, or steering during operation. The passenger also provides feedback relating to the vehicle's driving style during operation, and the passenger feedback is used to train the machine learning module to create a personal driving style decision-making model for the passenger that controls operation of the autonomous vehicle. A personal driving style preference profile for the passenger also may be obtained by collecting motion sensor data relating to driving habits of the passenger when the passenger is a driver. The driving style preference profile is used by the motion planner to modify operation of the autonomous vehicle in accordance with the driving style preference profile.

Abstract: A computer-implemented method for accessing user resources in a virtual private cloud (VPC) using a serverless function within a network architecture includes instantiating a first warm application container for hosting the serverless function. The first warm application container includes a runtime language library without function code of the serverless function. A virtual machine for hosting a Port Address Translation (PAT) gateway is instantiated. The PAT gateway includes a first interface to the VPC and a second interface to the first warm application container. In response to detecting a trigger event for triggering the serverless function, the function code of the serverless function is mounted within the first warm application container. During execution of the function code from the first warm application container, VPC-addressed network packets associated with the serverless function are routed to the VPC via the second interface and the first interface within the PAT gateway.

Abstract: The disclosure relates to technology for mapping events to workflow instances. One or more event messages are received with an embedded token from one or more event sources associated with an application. A workflow specification is received that specifies a location of the token embedded in the one or more event messages, and the token is extracted from the one or more event messages using the location of the token specified in the workflow specification. The events are then mapped to a workflow instance of the application based on the token the one or more event messages.

Abstract: A novel scheme is defined for supporting service graphs to allow specific service functions to be applied to selected subsets of packet flows. According to one or more embodiments, a service graph is modeled as chains or sequences of “flow steering entities” and “service instances.” According to an embodiment, a flow steering entity (FSE) is configured to identify the flow, and select the next hop service instance in the chain. After a service instance returns the flow packet, the FSE steers the packet to the next FSE in the graph. An initial FSE is used to select matching traffic to enter the service graph. Wherever path forking and merging is required in the service graph, additional classifiers are positioned with the FSE to steer a subset of traffic along different paths of service function instances.
