The CFP for next year’s Velocity Conference is up now, so all you ops and performance ninjas submit your ideas for talks. I’m lucky enough to be on the program committee this year, and I think the conference is a huge opportunity to spread the ops love on all kinds of topics. There’s a list...

Gil Raphaelli, one of the guys on our Flickr Ops team, put together a Code Swarm animation for the configuration/deployment management tool we use at Flickr to manage our infrastructure. Myles Grant did this for our bug reporting system as well. Check it out: Our automated config management system is called Gemstone, but conceptually you...

Via kottke: some good examples of doing rough math in your head, causing you to guess about assumptions all along the way. IMHO, being able to do this is one of the things that makes a good web ops person. The examples might be “useless”, but the process is invaluable....

Production Changes/Immediate Issues We have our configuration management schemes wrapped up in...

Dear users of S3, EC2, and other ‘utility’ computing stuffs: Here’s a crude and completely oversimplified evolution of infrastructure needs of a growing website, with an assumption: Have you ‘outgrown’ your original use of utility computing, for whatever reason ? If so, what was the reason? Financial? Technical? Why I’m asking: I’m in the process...

I’m probably very late to this party, but I just discovered Dashboard Spy. Given the amount of “data porn” that folks in webops look at on a daily basis, this sort of stuff is pretty damn interesting. I’m especially loving the current trend of developing ‘business’ dashboards, since it can fit in quite nicely with...
