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.

Device state management

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.

Localized device coordinator with mutable routing information

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.

Transformation of machine learning models for computing hubs

A technology is described for managing dynamic groups of devices using device representations. An example method may include receiving a request for a dynamic group of device representations. In response to the request, a membership parameter used to identify member device representations included in the dynamic group of device representations may be obtained. Device representations may be queried using the membership parameter to identify member device representations that have a state that corresponds to the membership parameter, and the dynamic group of device representations may be generated to include identifiers for the member device representations.

Dynamic grouping of device representations

A technology is described for operating a device shadowing service that calculates an aggregated group state for a group of device representations. An example method may include receiving device states for devices represented using a group of device representations, where the devices connect over a network to a device shadowing service configured to manage the device states. In response to an event, device representations included in the group of device representations may be identified. Device states indicated by the device representations may be obtained and an aggregated group state for the group of device representations may be calculated using the device states indicated by the device representations.

Aggregated group state for a group of device representations

Technology is described for controlling different types of physical devices in a device farm hosted in a service provider environment. A removable storage slot adapter may be physically inserted into a removable storage slot of a physical device. The removable storage slot adapter may present an emulated removable storage device using a removable storage configuration obtained over a network from a management service hosted by the service provider environment. The removable storage slot adapter may interpret commands from the device to access data blocks of the emulated removable storage device. The removable storage slot adapter may access a storage service hosted by the service provider environment to fulfill the commands and data access operations requested from the device.

Device communication environment

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.

Group command management for device groups

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 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.

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.

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 and process the message to determine how the communication message will be routed or otherwise processed according to business rules or logic.

Managing messaging protocol communications

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.
