Abstract
In general, techniques are described for proxying, with a locally-deployed computing device, service requests from one or more with customer devices to a remote data encryption and key management service and assuming, by the local computing device, the service functions of the remote service in the event of a remote service failure. For example, customer devices at a location may be configured to communicate service requests to the local computing device rather than to a remote service. The local computing device obtains one or more encryption keys or other security objects and stores the security objects to local storage. In response to determining a disruption in the remote service due to, e.g., network connectivity failure, the local computing device may assume the functionality of the remote service for a limited time by performing data encryption operations, responsive to requests received at the local computing device from the customer devices.
