Serving images at Criteo

At Criteo, we serve billions of images every day, and every day this number increases. Our legacy C/C++ solution was not scaling anymore, so we decided to give Finagle try for a first public facing service. In this talk we will present how we did, using Finagle not only to serve these images to our users, but also to fetch them from our partners as well, all at quite a large scale.
