Abstract: A technology is described for managing device performance capabilities. An example method may include connecting a physical device electronically to a service provider environment using a computer network and identifying performance capabilities of the physical device at the service provider environment via the connection. A request may be received at the service provider environment to upgrade the performance capabilities of the physical device and an authorization may also be received at the service provider environment for the upgrade. The performance capabilities of the physical device may be upgraded by sending an upgrade instruction from the service provider environment to the physical device to unlock additional performance capabilities based on the authorization. The performance capabilities of the physical device may later be downgraded to by disabling the additional performance capabilities of the physical device.

Abstract: Technology is described for migrating connections for Internet of Things (IoT) devices. Data packets may be received from an IoT device for forwarding to a first physical host in a computing service environment. A determination to migrate the connection for the IoT device from the first physical host to a second physical host in the computing service environment may be performed when a throughput of the data packets received from the IoT device for the first physical host exceeds a defined threshold. A connection migration procedure may be initiated to migrate the connection for the IoT device from the first physical host to the second physical host. The connection migration procedure may include an exchange of session state information for the IoT device from the first physical host to the second physical host to enable the migration of the connection to the second physical host.

Abstract: Compute hosts and a routing system may be used for connection and application state migration for uninterrupted service availability. In response to an indication to transfer a connection from a particular compute host to another compute host, the particular compute host obtains a connection state and an application state for the connection and sends the connection state and the application state to the other compute host. The connection state includes information for a connection-oriented protocol and the application state includes information for an application-layer protocol. The other compute host receives and applies the connection state and the application state in order to establish a termination point to terminate the connection at the other compute host instead of at the particular compute host. The data for the connection is routed to the other compute host, wherein the client is unaware of transfer of the connection to the other compute host.
