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?

SSH Tips -1
===ESCAPE CHARACTERS===
When a pseudo-terminal has been requested, ssh supports a number of func‐
tions through the use of an escape character.
A single tilde character can be sent as ~~ or by following the tilde by a
character other than those described below. The escape character must
always follow a newline to be interpreted as special. The escape charac‐
ter can be changed in configuration files using the EscapeChar configura‐
tion directive or on the command line by the -e option.
