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?

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

For a moment, I'm going to throw away my automation and configuration management hat. I'll let you know when I put it back on. Also, let's ignore that we're talking about Riak specifically for a moment. Also also, let's ignore any (for a brief moment) the proper role of a package manager.

What's your target market?

If you're writing server software, you have two target markets. The system administrator/operations team and the developer.

Why do you want autostart?

The main reason you want autostart is to get people up and running quickly. To do this, you need to ship safe and sane defaults. This means something like a default configuration that listens only on localhost.
