News For most companies, development and operation teams play a game of volleyball passing blame on each other when service/product has issues. Lack of communication and understanding between the two, causes costly and timely problems for every company. DevOps is not a title, nor is a position. DevOps is culture represented by a white flag waved from both directions. Cooperation and Communication are at the heart of DevOps. It tears down the wall and pride of these two very valuable entities inside a company and unleashes the power of teamwork towards a common goal!

This past week I had the privilege to peek behind the curtain of a service provider that has become a streaming titan in a relatively short time. We all have been guilty of hanging up our responsibility coat at the door, and binge watch a favorite show on a variety of devices. Netflix, kindly sent a representative at the 2016 SQL Pass conference to skim over some of their technologies and processes. As expected they do a LOT of data processing. How do they do it so efficiently and with excellence? Well, the following slide answered that....and opens a whole other bag of questions:


Based on advanced and continuous analytics, Netflix has figured that any customer decides whether to watch a show within 60-90 seconds of being presented with the splash screen. This means that the company must be intentional about the content and its UX. Therefore, Netflix has about 86 million different versions of their app across different devices. 

We have all heard the saying: "Opinions are like everyone has one and it stinks". 

For this reason, Netflix only allows data to dictate implementation of future features and design. They A/B test all contenders, and may the best option win. Below is a representation of their “simple” A/B testing model:



In effort to keep this post short, below are some facts that intrigued me:

  1. Netflix has converted into an entertainment company with their own production studio.
  2. Their analytics allow them to decide what original content to product rather than license.
  3. All of the infrastructure is in AWS cloud (Absolutely love it!)
  4. They do not use any Microsoft technology (There is always hope...)
  5. They have the culture of Freedom & Responsibility. Every single bit of data is available for access by any internal employee, including production data. 
  6. They are always hiring.

At the end of the session, I congratulated the presenter to which she asked if I had any questions. My answer…” So many, but have no idea where to start….”. Their elastic infrastructure allows for so much scalability, coupled with other non-technical efforts makes them the 800lb gorilla in the marketplace. Per statistics, Netflix represents 35% of internet streaming. The other “small pups” such as YouTube and Amazon Prime are only in the low teens.
