Internet Scale Services Checklist

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."

Basic tenets

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

" Description: A minimal, but feature rich, example .vimrc. If you are a
" newbie, basing your first .vimrc on this file is a good choice.
" If you're a more advanced user, building your own .vimrc based
" on this file is still a good idea.
