A while ago I blogged about how F5 was making mongrels better with a Side of Mayo.  I referenced a blog post on Joyent's wonderful Joyeur blog on why Joyent uses F5's BIG-IP for their customers.  Well, those krazy kids at Joyent are at it again...

joyeurPlusLinkedIn In a recent post, Joyent point out how LinkedIn, a customer of theirs, built a Facebook application called BumperSticker using Ruby On Rails.  LinkedIn made use of Joyent's Accelerators and our very own BIG-IP to scale Ruby on Rails to some very significant numbers.

  • 13.5 million installations
  • 1.5 million daily active users
  • 20-27 million canvas page views a day

All this is served by

  • 13 web application servers running nginx and mongrel.
  • 8 static asset servers serving over 3,500,000 stickers, soon to migrate to a CDN.
  • 4 MySQL servers in a master/slave configuration using Rick Olson's excellent masochism plugin.

For those video inclined, Joyent has an added bonus: check out the video they put together on the subject.

So, as the Twitter's out there continue to have availability issues and the debate continues as to the scalability of Ruby on Rails, BIG-IP helps show that with a good design and infrastructure planning, big things are possible.  Keep up the good work Joyent!  Oh, and if you ever want to do a guest spot on the DevCentral Podcast, please let us know.  Oh, and if you ever need a guest for your Quad Core podcast, let me know - I'd be glad to sit in!
