Replay Traffic Testing Replay traffic refers to production traffic that is cloned and forked over to a different path in the service call graph, allowing us to exercise new/updated systems in a manner that simulates actual production conditions. This approach has a handful of benefits.

We are constantly innovating on video encoding technology at Netflix, and we have a lot of content to encode. large portions of the entire Netflix catalog are re-encoded whenever we’ve made significant advancements in encoding technology. What problem are we solving? Encoding is not a one-time process?—?large We have one file?—?the

The Dynamo paper was well-received and served as a catalyst to create the category of distributed database technologies commonly known today as "NoSQL." " Of course, no technology change happens in isolation, and at the same time NoSQL was evolving, so was cloud computing.

For example, the most fundamental abstraction trade-off has always been latency versus throughput. Modern CPUs strongly favor lower latency of operations with clock cycles in the nanoseconds and we have built general purpose software architectures that can exploit these low latencies very well. Where to go from here?

Traditional IT projects are mass economy-of-scale exercises: once development begins, armies of developers are unleashed. But of bigger concern is the latency between the time when requirements are captured and the time they're available as working code in an environment. An Agile team is not an exercise in scale. much earlier.
