How Netflix Should Recover From Amazon Addiction – Forbes

So until a startup is rich and successful, it makes sense to just live with your Amazon addiction and suffer the occasional outage with the “blame Amazon” explanation. Startup CEOs should be sure to tell everyone about this dependency in advance so that such a failure doesn’t come as a surprise. But Netflix is beyond that stage. It is time for Netflix to start recovering from Amazon addiction and take full responsibility for the quality of its service.

Edda – Learn the Stories of Your Cloud Deployments – Netflix Tech

Edda is a service that polls your AWS resources via AWS APIs and records the results. It allows you to quickly search through your resources and shows you how they have changed over time.

Previously this project was known within Netflix as Entrypoints (and mentioned in some blog posts), but the name was changed as the scope of the project grew. Edda (meaning “a tale of Norse mythology”), seemed appropriate for the new name, as our application records the tales of Asgard.

I feel vindicated by what Netflix did with the results of the Netflix Prize.

1. Fancy ML techniques don’t matter. The winning BellKor/Pragmatic Chaos teams implemented ensemble methods with something like 112 techniques smushed together. You know how many of those the Netflix team implemented? Exactly two: RBM’s and SVD.

2. Domain knowledge trumps statistical sophistication. This has always been the case in the recommendation engines I’ve done for clients. We spend most of our time trying to understand the space of your customers’ preferences — the cells, the topology, the metric, common-sense bounds, and so on. You can OO program these characteristics. And (see bottom) doing so seems to improve the ML result a lot.

3. What you measure matters more than what you squeeze out of the data
