At AWS, we don't mark many anniversaries. A concept that has changed infrastructure architecture is now at the core of both AWS and customer reliability and operations. Powering the virtual instances and other resources that make up the AWS Cloud are real physical data centers with AWS servers in them.

In that scenario, the system would need to deal with the data propagation latency directly, for example, by use of timeouts or client-originated update tracking mechanisms. We started seeing increased response latencies and leader servers running at dangerously high utilization.

Uploading and downloading data always come with a penalty, namely latency. It is worth pointing out that cloud processing is always subject to variable network conditions. Doing so has the added advantage of being able to design and tune the enhancement to suit the requirements of packager and our other encoding applications.
