Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

• http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

• Does the design expect failures to happen regularly and handle them gracefully?
• Have we kept things as simple as possible?

Quick, take a guess, what's the first hop latency to your home wireless router?

Below 1ms, right? Yeah, you wish!

Below are results from a quick test on my home router (Linksys E1550). Some lessons learned:

• 3-8ms median
• very different latency tails on different channels (1,6,11)
• running in mixed mode helps tame the long tails (do it, if you can)
• all tests on 2.4Ghz, unfortunately E1550 can't do 5Ghz
