Here’s a video detailing how LinkedIn built an application (Bumpersticker on the Facebook platform) using Rails (and C Ruby!) that serves up more than 1 billion page views a month.
In my opinion, this ends the debate about whether Rails scales. Rails is a component, it is how the components are architected and delivered that comprises the magic. LinkedIn did amazing work taking advantage of Joyent’s technology stack including innovative ways of leveraging Joyent Accelerators and our BigIP load balancers.
Congratulations to the LinkedIn team. Great accomplishment! You can read more about the how LinkedIn scaled bumpersticker on Joyent in a post on their blog entitled Web Scalability Practices: Bumper Sticker on Rails
