Abstract: A computing environment is disclosed that receives from devices requests directed toward services accessible in the environment, and that forwards communications from services in the environment to devices registered with the environment. During a registration process at the environment, devices are assigned a device identifier that is used to identify and authenticate each particular device and requests communicated from and to the device via the environment. The computing environment maintains state information for each device that has been registered with the system. As the device interacts with the system, the state information is updated to reflect the changes in the device. When requests to perform functions are received from devices, the computing environment determines for the particular device and the particular function requested what processing needs to be performed by the environment in response to the request.

Abstract: Systems and methods are described for implementing a coordinator within a coordinated environment, which environment includes set of coordinated devices managed by the coordinator. The coordinator can be provisioned with a set of tasks, each task corresponding to a segment of code that can be executed by the coordinator, such as to manage the coordinated devices. The coordinator can further be provisioned with event flow information designating a routing of inputs to the coordinator computing device to destinations, such as task executions or coordinated devices. On receiving input, the coordinator can reference the event flow information to pass the input to an appropriate destination.

Abstract: Technology is described for providing machine learning (ML) models. A plurality of candidate ML models that are derived from a primary ML model may be generated in a service provider environment. The primary ML model may be associated with a set of parameters and a candidate ML model in the plurality of candidate ML models may be associated with a subset of the parameters associated with the primary ML model. The plurality of candidate ML models may be run against validation data to evaluate performance criteria for the candidate ML models. A performance representation of the candidate ML models with respect to performance results for the candidate ML models may be provided. An ML model may be selected from the performance representation based on the performance results for the candidate ML models.

Abstract: A technology is described for operating a device shadowing service that manages commands associated with groups of device representations. An example method may include receiving a group command associated with a group of device representations managed by a device shadowing service. Device representations included in the group of device representations represent physical devices that connect to the device shadowing service over one or more computer networks. In response to the group command, the device representations included in the group of device representations may be identified and an instruction to perform an action indicated by the group command may be sent to the physical devices represented by the device representations. Thereafter, indications may be received that at least a portion of the physical devices performed the action.

The coordinator can be provisioned with a set of tasks, each task corresponding to a segment of code that can be executed by the coordinator, such as to manage the coordinated devices. To assist in execution of the tasks, the coordinator can include a remote interface that enables retrieval of task calls from an external system, such as an external on-demand code execution environment. The remote interface may periodically retrieve calls from the external system, and generate corresponding call messages on the coordinator to cause executions of called tasks. The remote interface can further obtain outputs of such executions, and report those outputs to the external system.

Abstract: A technology is provided for adapting a quorum size of messaging nodes in a service provider environment. An adaptive quorum evaluation is executed to determine a number of messaging nodes for a quorum of messaging nodes. A messaging environment trigger is identified to change the number of messaging nodes used for the quorum of messaging nodes. The number of messaging nodes used for the quorum of messaging nodes is changed based on the messaging environment trigger. Data for the message is synchronized with a quorum of messaging nodes before delivering the message.

Abstract: Systems and methods are described for management of data transmitted between computing devices in a communication network. An administrative component can configure one or more devices in the communication path of messages to be exchanged by devices to interpret codes embedded in the communication messages. A receiving device can review incoming messages for one or more processing codes or instructions that are embedded in the portion of the communication typically utilized solely to identify the subject matter of the communication, generally referred to as the topic portion of the communication. The receiving devices can then process the embedded codes to determine how the communication message will be routed or otherwise processed.

Abstract: Systems and methods are described for implementing a coordinator within a coordinated environment, which environment includes set of coordinated devices managed by the coordinator. The coordinator can be provisioned with a set of tasks, each task corresponding to a segment of code that can be executed by the coordinator, such as to manage the coordinated devices. To assist in execution of the tasks, the coordinator can include a resource manager that generates execution environments corresponding to an individual task execution, which environments may be isolated from other execution environments. The coordinator can further include a scheduler to obtain calls to execute tasks, and implement a queue from which to select tasks for execution. On selecting a task, the scheduler may interact with the resource manager to generate an execution environment for the task, and cause execution of the task within the execution environment.

Abstract: Systems and methods are described for implementing a coordinator within a coordinated environment, which environment includes set of coordinated devices managed by the coordinator. The coordinator can be provisioned with a set of tasks, each task corresponding to a segment of code that can be executed by the coordinator, such as to manage the coordinated devices. To assist in execution of the tasks, the coordinator can include a communications manager that enables communications between tasks. The communications manager can provide a language-independent interface to call for execution of tasks, pass information to a task, and obtain outputs of a task. In some embodiments, the communication manager may utilize a language-independent protocol, such as the hypertext transport protocol, and be configured to respond to requests addressed to uniform resource identifiers associated with the communications manager.
