Abstract: Methods and systems for multi-device, multi-channel cloud-based differential data synchronization. The system includes a server system, a source device including a first migration application instance, the source device configured to execute the first migration application instance to initiate a data transfer process with the server system to transfer user data to the server system upon a user ordering a target device, and the target device including a second migration application instance, the target device configured to execute the second migration application instance to initiate a data transfer process with the server system to transfer the user data to the target device, and execute a second data transfer with the source device to finalize data synchronization when the user is picking up the target device.

Abstract: A distributed storage system includes an orchestration layer that provides policy driven orchestration for controlling access and/or load balancing in connection with servicing I/O requests from one or hosts at one or more compute sites in a cloud configuration. The I/O requests may be received over a communication link, and the orchestration layer maintain policies and/or other information that control the selection of an compute site for processing of the I/O according to one or more policies and based on tiering designations of the compute sites. For example, according to various embodiments, policy information of the orchestration layer may control the passing of I/O requests to the one or more compute sites with respect to such factors as requirements of particular service legal agreements, specific tolerances for handling the I/O requests and/or times and rates for processing I/O requests at particular compute sites.
