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?

# If you use bash, this technique isn't really zsh specific. Adapt as needed.
source ~/keychain-environment-variables.sh

# AWS configuration example, after doing:
# $  set-keychain-environment-variable AWS_ACCESS_KEY_ID
#       provide: "AKIAYOURACCESSKEY"
# $  set-keychain-environment-variable AWS_SECRET_ACCESS_KEY
#       provide: "j1/yoursupersecret/password"
export AWS_ACCESS_KEY_ID=$(keychain-environment-variable AWS_ACCESS_KEY_ID);
export AWS_SECRET_ACCESS_KEY=$(keychain-environment-variable AWS_SECRET_ACCESS_KEY);

For symmetic encryption, you can use the following:

To encrypt:
openssl aes-256-cbc -salt -a -e -in plaintext.txt -out encrypted.txt

To decrypt:
openssl aes-256-cbc -salt -a -d -in encrypted.txt -out plaintext.txt


For Asymmetric encryption you must first generate your private key and extract the public key.
