Hi, Go to Packstack it's easy to install (relatively) and it's well supported Also it has more standardized development. As for Swift you can use it and work on the source code if you have Packstack installed and running ...

In RDO Mitaka and Liberty Swift may be installed via packstack on separate storage node see :-

In RDO Newton release (oncoming release )

 Be aware of in oncoming Newton RDO release you are supposed to see following output.Yes,it does work and in fact drops packstack as tool for production deployments ( storage.pp is missing ). 
    [root@Server72CentOS templates]# pwd
    /usr/lib/python2.7/site-packages/packstack/puppet/templates
    [root@Server72CentOS templates]# ls -l
    total 16
    -rw-r--r--. 1 root root 2204 Aug  9 12:33 compute.pp
    -rw-r--r--. 1 root root 5918 Aug  9 12:33 controller.pp
    -rw-r--r--. 1 root root 1516 Aug  9 12:33 network.pp

In other words without hacking packstack and creating storage manifest, swift would be installed on Controller, what is obviously hardly acceptable for systems using swift uploads and etc.
