A google server
Google storage was recently released as an open beta for developers to work with. All in all it seems like an Amazon S3 clone and whilst they have their REST api for integration they also support the Amazon S3 api.
Originally I was planning on writing a ruby wrapper of this api but decided to see if I could modify with existing aws-s3 gem to work with google storage.
After some in depth reading of both apis and understanding of the aws-s3 gem I have modified it to also work with google storage.
My github fork contains these modifications.
require 'aws/s3' include AWS::S3 Base.establish_connection!( :access_key_id => 'abc', :secret_access_key => '123', :default_host => "commondatastorage.googleapis.com" )
Note the addition of the default_host to connect to google instead of AWS.
From then on you can use the gem as normal as is described in the Readme.
