How is Netflix able to manage this so effectively and still serve ~30% of US traffic off AWS?<p>I&#x27;ve heard the non-AWS folks talk of these vendor lock ins or long term costs but aren&#x27;t those irrelevant in 2016+? eg. microservices to reduce the issue of vendor lock in and long term costs on infrastructure that goes out of date every 2-3 years is a poor planning indicator no?
