refinery cms

=> most popular rails cms

=> “follows the rails (3) way”

=> simple, modular, extendable

=> good enough

git

=> by Linus for Linus

=> every Git working directory is a full-fledged repository with complete history and full revision tracking capabilities

=> independent of network access or central server

basic git workflow (from scratch)

$ cd (project-directory)

$ git init

$ (add some files)

$ git add .

$ git commit -m 'first commit'

heroku

=> user friendly web app deployment/management/scaling

– rack apps(rails, sinatra)x, node.js, clojure

=> sits on top of AWS – goes down when AWS goes down

=> easy to migrate away from– no lock-in

=> stack promotes best practices

heroku cont.

=> basic package can get you a long way

=> read-only filesystem

=> git-based deployment

putting the pieces together=> prerequisites : ruby, rubygems, rails, sqlite3/mysql, git
