Disclosed are various embodiments for provisioning radio-based networks with locality rules. In one embodiment, at least one locality rule associated with an organization is accessed. The locality rule(s) require that at least a subset of network traffic for a radio-based network remain within a particular geographic area. The radio-based network includes a radio access network and an associated core network. A topology for the radio-based network is determined based at least in part on the locality rule(s). The radio-based network is provisioned or reconfigured for the organization to have the topology complying with the at least one locality rule.

This disclosure describes systems, devices, and techniques for migrating virtualized resources from outdated hosts during requested reboots of the virtualized resources, in order to update the outdated hosts. In an example method, a pending reboot a virtualized resource occupying a first host can be identified. At least one component of the first host may be determined to be outdated. In response to identifying the pending reboot and determining that the at least one component is outdated, the virtualized resource may be migrated to a second host. The first host may update the at least one component.

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.

This disclosure describes systems, devices, and techniques for quick restarts of virtualized resources hosted by a cloud-based network. In an example method, a request to restart a virtualized resource hosted by a first server can be received. A second server, with a capacity to host the virtualized resource, may be identified. In response to identifying the second server, the virtualized resource can be migrated from the first server to the second server. A message confirming that the virtualized resource has been restarted may be transmitted.

Methods and apparatus for post data synchronization in live migration of domains. Host devices on a network may implement virtual machines (VMs) as domains in an execution environment, and may provide local persistent storage for data of the VMs. A migration technique for moving a domain including the persistent data from one host device to another host device is described in which the VM is instantiated on the target device, and the domain is switched to the target device. Synchronization of the VM's data from the persistent storage on the source device to the target device is then initiated, for example according to a distributed replicated storage technique that makes the target device's persistent storage the primary storage and the source device's persistent storage the secondary storage for the VM. Once the data is synchronized, the VM and its respective storage on the source device are released.

Post data synchronization for domain migration

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.

On-demand code execution in a localized device coordinator

Systems and methods are described for configuring a coordinator within a coordinated environment, which environment includes set of coordinated devices managed by the coordinator. The coordinated devices may include devices configured to be managed remotely, such as thin devices, devices with alternative primary functions (e.g., appliances, household objects, etc.), or devices with limited localized user interfaces. To manage the set of coordinated devices, the coordinator can execute tasks, each task corresponding to a set of portable code executable by the coordinator to implement a desired functionality. A user may generate one or more tasks, and submit them to a service provider environment for deployment to the coordinator. The service provider environment can utilize a device shadow to notify the coordinator of the obtained tasks, and thereafter deliver the tasks to the coordinator, thus modifying a configuration of the coordinator.

A technology is described for assigning a logical private network address to a computing instance. An example method may include obtaining a preserved logical private network address associated with a customer account so that the preserved logical private network address may be assigned as a logical private network address to a computing instance located in a computing service environment. The logical private network address may be used for network communications within a physical host containing the computing instance and the logical private network address may translate to a physical private network address used for network communications outside of the physical host and within the computing service environment. A network address record for the computing instance may be identified that associates the logical private network address with the physical private network address, and the network address record may be updated by setting the preserved logical private network address associated with the customer account as the logical private network address.
