Sessions at RailsConf 2012 about Scaling and Ruby on Rails on Monday 23rd April

New Relic CEO Lewis Cirne will lead a panel discussion with representatives from some of today's most popular, highly-trafficked web sites. With millions of uniques a month, find out how these organizations are optimizing their Rails-based sites for mobile, for unexpected traffic bursts, and for seasonality.

Curious how Spiceworks, a social business app built on Rails, keeps 2 million active users happy? With Ruby on Rails, baby! In the last year our usage has increased 8x and now exceeds 200 million requests per month. Join Francis Sullivan, CTO and Co-founder, and David Babbitt, Technical Program Manager, to hear about the architecture and best practices we adopted to make this happen.

Get the ins-and-outs on:

• Hosting a high volume Rails application
• Choosing what to optimize
• Lessons learned while moving to JRuby
• Updating a large codebase through Rails beta to Rails 3
• Scaling the dev organization

StillAlive.com was born from the 48 hour intense 2010 Rails Rumble and has grown! Having recently passed our 50,000,000th site result, this talk discusses the real world challenges and optimisations required to take a code base born from the fires of YAGNI to a production system.

This talk isn't about how you can scale from 0 requests to 500 billion requests per microsecond, but give a practical view to some of the performance problems we faced as the application steadily grew from a hack job into a functioning system.

The journey will go through the mistakes we made, challenges faced and real world optimisations discovered, including some tricks we learnt along the way from concurrent index creation to using the ZeroMQ messaging framework with Rails
