For all the complaints about Netflix (NASDAQ:NFLX), the most legitimately worrisome may be its dependence on chief competitor Amazon.com (NASDAQ:AMZN).

By most accounts, the streaming sensation couldn't deliver as much video as it does without the help of Amazon Web Services. Trouble is, AWS has gone wobbly in recent months. A Christmas Eve outage took out Netflix, too, resulting in a lot less holiday cheer.

Whatever issues were at work then appear to have been solved. But Netflix also isn't taking chances. The company is slowly moving core pieces of infrastructure off Amazon, including infrastructure that controls the way users managers their "queue" of streamed shows and to-be-shipped DVDs.
