Netflix’s Success through Technology and Culture - Andicom 2014
Oct 28, 2014
Netflix is the world's leading internet television network. In this presentation, I talk about the aspects of Netflix culture that have contributed to its success. The freedom and responsibility culture, with highly aligned, loosely coupled teams of amazing, enthusiastic, helpful, high performance people with excellent judgement has helped build Netflix to adapt and change quickly, and iterate to make the best service possible. By eliminating rules and processes, and ensuring that employees have the contexts of the business in all aspects, Netflix has enabled employees to use their judgement to get things done rather than relying on control or process. This has resulted in Netflix becoming a leader in not only internet streaming, but also cloud computing, media, and culture. Because of the Netflix culture, we have been able to attract and retain great employees.
I give a few examples from my team, Edge Engineering of how the culture enables us to build the high scale, resilient and dynamic services that are the front door to the Netflix streaming application, and how the freedom we have has enabled us to open source core technologies that are needed for large scale, service-oriented architectures in a cloud environment.
This slideshow also gives a high level overview of how the streaming service works, and how Netflix's Open Connect Appliance can help ISPs.
