Abstract
A device-management system performs processing, such as audio processing, in an instance of a virtual machine corresponding to a functionally limited (local) device. To register the user device, the device-management system receives a registration request that includes device information, encryption data, and an indication of an associated user account. The device-management system then sends this registration data to a service-provider system, which returns a shared encryption key. The device-management system and the user device may use this shared encryption key to securely communicate. The device-management system may de-allocate the instance upon detecting a period of inactivity of the user device and may re-allocate the instance when new activity is detected. The device-management system may further determine when and if audio data to be sent to the user device is encoded using a codec not implemented by the user device. Upon this determination, the device-management system may transcode the audio data such that is encoded using a known codec.
