In the Belly of the Whale: Operations at Twitter
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!
Now this is the kind of presentations I want to see… +++
Great presentation, thank you John for sharing your insights into the challenges you face at Twitter.
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?
That was like drinking from a fire hose – lots of great stuff!
