Track: Architectures You've Always Wondered About


Day of week:

Have you ever browsed to a site like eBay or Amazon and wondered, or even fantasized about what software architecture they may have used, and what insights their teams must have after solving such complex and large-scale problems? This track will give you an exclusive chance to learn directly from some of the most well-known and high-volume web applications in the world.

Track Host:
Randy Shoup
Consulting CTO (former Google and eBay)
Randy Shoup is Consulting CTO. Randy has worked as a senior technology leader and executive in Silicon Valley at companies ranging from small startups, to mid-sized places, to eBay and Google. In his consulting practice, he applies this experience to scaling the technology infrastructures and engineering organizations of his client companies.

by Matt Ranney
Chief Systems Architect at Uber, Co-founder of Voxer

Matching riders with drivers is an interesting problem, but as Uber moves into new markets with new services, the existing architecture breaks down. As a result we've completely redesigned the realtime market system to be more flexible, scalable, and available.


This talk will explain the Uber architecture overall, with a focus on the dispatch systems. We'll talk about the geospatial index we built, how we handle datacenter failure, and our approach to the distributed...

QCon Open Space Facilitator

Open Space

Join Randy Shoup, our speakers, and other attendees for the Architecture Open Space.

What is Open Space?

Every day at QCon London, we’ll open space five times, once for each track. Open Space is a kind of unconference, a simple way to run productive meetings for 5 to 2000 or more people, and a powerful way to lead any kind of organization in everyday practice and extraordinary change.

by Jason McHugh
Facebook Engineer

In April 2013 Facebook acquired the Atlas Advertising Suite from Microsoft. The Atlas system was originally an independent company started in 2001, later purchased by aQuantive, and then purchased by Microsoft in 2007 for $6 billion. Atlas is a third party ad server with a focus on campaign management and results tracking. It serves billions of ad impressions each day.

It quickly became apparent that we wouldn't be able to continue to run the Atlas software stack in its current form...

2:30pm - 3:20pm

by Randy Shoup
Consulting CTO (former Google and eBay)

Over time, almost all large, well-known web sites have evolved their architectures from an early monolithic application to a loosely-coupled ecosystem of polyglot microservices. While first-order goals are almost always driven by the needs of scalability and velocity, this evolution also produces second-order effects on the organization as well. This session will discuss modern service architectures at scale, using specific examples from both Google and eBay.

It will cover some...

3:40pm - 4:30pm

by Yoni Goldberg
Lead Software Engineer at Gilt

Once built upon a monolithic Rails application, Gilt has spent the past few years transitioning to a distributed, scalable architecture based on hundreds of micro-services built in Scala.

In this talk, Gilt Lead Software Engineer Yoni Goldberg will discuss the many advantages that microservices can offer to has offered to the Gilt engineering team, as well as the challenges--and how Gilt’s engineers have gone about resolving these challenges. Yoni will also provide a deep-dive...

4:50pm - 5:40pm

by Niklas Gustavsson
Backend Engineer, Spotify

Spotify streams music to more than 60 million users from a catalogue of 30 million songs.

Spotify has long used what is now known as a microservice architecture. Its backend consists of hundreds of services, small and single purpose. It has allowed a continuous evolution of the Spotify feature set and has supported scaling out to supporting now more than 60 million users.

This talk will go into detail on how a Spotify service works and how the UNIX philosophy of composing...
