Architectures You've Always Wondered About

Architectures You’ve Always Wondered About (or AYAWA as we like to call it) is a staple of QCon and offers attendees a chance to go behind the scenes with some of the world’s most successful technology companies.

This year we have some incredible stories of how teams are evolving legacy technology (mainframes as part of a cutting edge tech stack!?) to deliver modern customer experiences and how hyper-scale businesses are developing compute platforms to enable rapid development whilst retaining reliability, performance, privacy and security.

When we were thinking about how to bring a unique perspective to this year’s track, the global nature of many systems was top of mind. Building global applications poses many challenges, especially for large scale streaming applications. Keep an eye out for some talks that deep dive into how teams are designing their architectures to avoid the hardest problems, pitfalls and trade-offs.

If you’ve ever wondered how well-known tech companies seamlessly deliver an exceptional user experience or scale systems to support near real-time streaming to billions of customers then AYAWA will not disappoint.

Sergey Fedorov

Director of Engineering @Netflix

Sergey is a hands-on engineering leader with over 15 years of experience in global infrastructure and distributed systems. At Netflix he worked on a range of components in the Content Delivery domain, like building a monitoring system for the Open Connect CDN infrastructure, launching  FAST.com speed test, accelerating device-AWS requests and improving Netflix traffic management. Today Sergey is leading the engineering effort to enable Live Streaming functionality for Netflix users. 

Sergey is a vocal advocate of an observability approach to engineering and making data-driven decisions. Finding actionable signals in loosely controlled environments is what keeps him awake, much better than caffeine. This might also explain why outside of work Sergey can be seen playing ice hockey, brewing beer, or exploring exotic travel destinations.
