The biggest software systems on the planet need sophisticated architectures, deliberately and carefully designed to support true planet-scale, along with high availability, durability, security, and many other concerns.

These systems are often mysterious to outsiders - that’s why they make such good interview questions! Architectures You’ve Always Wondered About is QCon’s marquee track, featuring leading engineers from the world’s best tech companies walking us through the necessary complexity of these leading-edge systems. As well as frankly being very interesting, the design processes, results, and lessons learned along the way are something we can all learn from and take back to our own architectures.
