Great overview of the technology choices and how they interact. I really appreciate when important companies reveal some of the inner workings of their sites. It gives something for the rest of us to go on. It can help inform our judgement when we make similar choices. This happens all too rarely. Many thanks!

Thanks, we hope to go deeper in areas people are interested in. Let us know.

I'd love to see you go deeper into devops. How are changes pushed? How often do you push changes? How are changes tested? How do you performance test at scale? How do you recover if something goes wrong?

Hi! We posted something that somehow answers that question.

Some parts of it are a bit outdated --we don't use Selenium tests for pre-testing all commits-- but overall it should give some idea of how deployment works at Digg.
