The Evolution of the Flickr Architecture, or I Love LAMP, 2010 Editionedit

A session at Strange Loop 2010

  • Mikhail Panchenko

Flickr was created over 6 years ago - an eternity in tech years. While the site's general architecture has has held up fairly well, some pieces have started creaking at the seams. A new crop of engineers has started evolving the site's architecture to take advantage of new technologies.

We'll discuss what the Flickr team is doing to keep up with the times while operating a quickly-aging, labyrinthian codebase. Topics will include, but will not be limited to:

MySQL
why it's still our hammer - some numbers
the tools we use to make managing MySQL easier
knowing when it's not the right tool for the job
Redis: picking up MySQL's slack
PHP
testing in a legacy, procedural codebase
introducing objects and exceptions without breaking things
Java: the dark horse; how we use various specialized daemons to help scale the site
Hadoop: crunching the numbers
Frontend performance: Going from 5 seconds to below ~1
Deploying: we still deploy ~10 times a day and it's still awesome
The topics will be accompanied by appropriate war stories. Come hear what a new generation of engineers is doing to keep Flickr running smoothly as it continues to grow. If you're not interested in that, come laugh at the tales of all the unbelievably dumb things we've done over the years.
