Netflix engineers were spending too much time working with infrastructure and not enough time on their media algorithms, so they created Archer, a high-scale distributed computing platform for media processing. It uses Docker, which allows developers to write their code in any language with any OS packages, test it on a laptop, and run it with millions of compute hours. This talk will discuss the Archer platform architecture as well as its implementation and applications, including feature extraction, encode experimentation, and machine learning.
