John will cover many aspects of Twitter’s scaling efforts, including:

  • Finding the weak points in Ruby on Rails, and repairing them.
  • In house Peer-to-Peer: High speed deploys across thousands of machines in no time at all
  • Managing thousands of machines: Why you need a central machine database, now.
  • User management: How do you onboard many new developers and still remain fault tolerant?
  • Caching methodologies and Twitter’s open source efforts (Scarling, CacheMoney, Libmemcached)
  • Asynchronous versus Synchronous processing during request lifetime
  • Life after Syslog: What do do when it won’t work anymore.

Great presentation. I was blown away by the mention of “statistical analysis” and “modeling” – never heard that before in the web world!

Hey, you mentioned moving from Proxy Balancer to ProxyPass but the slides said you moved ProxyPass to Proxy Balancer – I tend to believe PB -> PP more but can you clarify?
