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?

We're working on a project that uses the Datomic Pull API to pull specific attributes out of Datomic entities. Here's an example of query that uses the Pull API:

(d/q '[:find [(pull ?e [:sales/deal_number :sales/deal_close_date :sales/state]) ...] 
       :in $ ?date 
       :where [?e :sales/deal_close_date ?d _ _] [(> ?d ?date)]] 
       db 
       (days-ago-at-midnight 1))

Project

Project Setup

How do I, as a developer, start working on the project?

1. What dependencies does it have (where are they expressed) and how do I install them?
2. How can I see the project working before I change anything?
