I use Fabric - http://pypi.python.org/pypi/Fabric/ http://pypi.python.org/pypi/Fabric/ - with a series of build scripts. I can create and update several different types of EC2 servers (database, app, etc) with a single commands. The update command does something like this: * Check out all pertinent application files from the repository. * Add any production specific files, for example build number or database setups * Combine, compress, and number all Javascript and CSS files (combined.384.css can be cached forever, on update it becomes combined.385.css) * Tar and gzip the production files * Find all EC2 servers that need to be updated * Upload the gzipped files * Stop apache * Remove old files on the server(s) * Unzip the new files * Start apache
