Hi Marc, Coders yes, there are to much ways on keeping updated o teams or releases. My target on this thread is having "Infraestructure as code" as the DevOps manifest. I mean, having health on the continues integration / delivery as part of the development policies.
I usually use for my own a small script for deploy releases based on tryton, since for me is easier, and for deploy on production just using it inside virtual env, however having deploying policies inside the health team, could help development process and deploying stagesm and problaby have an extre tool like BuildBot or jenkins or just a simple shell script for deploying with just a crontab without a human activation.
