As CTO of DoubleClick, we scaled to serve 400,000 ads/second. We developed and used many custom data stores long before “nosql” was a buzzword. Over the years, I’ve seen companies I’ve worked with struggle with both scalability and agility. Writing the first lines of MongoDB code in 2007, we drew upon these experiences building large scale, high availability, robust systems. We wanted MongoDB to be a new kind of database that tackled the challenges we were trying to solve at DoubleClick.

This session will focus on internet infrastructure scaling and also cover the history and philosophy of MongoDB.
