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

An update by Paul Johnston (paul@roundaboutlabs.com), for a Serverless Architecture scenario. This assumes something akin to AWS Lambda + API Gateway + DynamoDB (c. 2016) Function as a Service (FaaS) solution as the basis for deployment rather than a cloud-based virtual server approach which the original paper was based upon. The FaaS solution implies each function is separately scalable and the database is inherently partitioned (assuming designed/built well).

If you agree/disagree, please fork and share with me on twitter @pauldjohnston.

Commit, clone a container

To 'clone' a container, you'll have to make an image of that container first, you can do so by "committing" the container. Docker will (by default) pause all processes running in the container during commit to preserve data-consistency.

For example;

docker commit --message="Snapshot of my container" my_container my_container_snapshot:yymmdd

(a gist based on the old toolmantim article on setting up remote repos)

To collaborate in a distributed development process you’ll need to push code to remotely accessible repositories.

This is somewhat of a follow-up to the previous article setting up a new rails app with git.

For the impatient

Set up the new bare repo on the server:
