A logging and replay device , the device comprising: one or more shared services (131-142) including a replay service ; a processor for executing the one or more shared services (131-142); and a shared interface for providing access to the one or more shared services (131-142); wherein the replay service is configured to: select a log for playback; emulate a playback device associated with the log by: extracting a log entry from the log; recreating a service request for the one or more shared services based on information associated with the log entry; exchanging a synchronization message with a logging service, live device (160, 181-189, 210-230, 510, 520, 530, 540), or simulated device; estimating clock skew and latency based on information associated with the synchronization message; adjusting a timing and sequencing of the recreated service request based on the estimated clock skew and latency; and initiating the recreated service request; wherein the one or more shared services (131-142) are configured to push the recreated service request to a live device (160, 181-189, 210-230, 510, 520, 530, 540) operated by a user. one or more shared services (131-142) including a replay service ; a processor for executing the one or more shared services (131-142); and a shared interface for providing access to the one or more shared services (131-142); wherein the replay service is configured to: select a log for playback; emulate a playback device associated with the log by: extracting a log entry from the log; recreating a service request for the one or more shared services based on information associated with the log entry; exchanging a synchronization message with a logging service, live device (160, 181-189, 210-230, 510, 520, 530, 540), or simulated device; estimating clock skew and latency based on information associated with the synchronization message; adjusting a timing and sequencing of the recreated service request based on the estimated clock skew and latency; and initiating the recreated service request; wherein the one or more shared services (131-142) are configured to push the recreated service request to a live device (160, 181-189, 210-230, 510, 520, 530, 540) operated by a user. select a log for playback; emulate a playback device associated with the log by: extracting a log entry from the log; recreating a service request for the one or more shared services based on information associated with the log entry; exchanging a synchronization message with a logging service, live device (160, 181-189, 210-230, 510, 520, 530, 540), or simulated device; estimating clock skew and latency based on information associated with the synchronization message; adjusting a timing and sequencing of the recreated service request based on the estimated clock skew and latency; and initiating the recreated service request; extracting a log entry from the log; recreating a service request for the one or more shared services based on information associated with the log entry; exchanging a synchronization message with a logging service, live device (160, 181-189, 210-230, 510, 520, 530, 540), or simulated device; estimating clock skew and latency based on information associated with the synchronization message; adjusting a timing and sequencing of the recreated service request based on the estimated clock skew and latency; and initiating the recreated service request; wherein the one or more shared services (131-142) are configured to push the recreated service request to a live device (160, 181-189, 210-230, 510, 520, 530, 540) operated by a user. <EOS>
