Platform as a Service (PaaS) is the middle ground between
IaaS and SaaS [9]. With PaaS, using few commands (that could
be in a web console) the developer could start the whole
"virtual environment" along with all the "server" pieces
required to run the application. Then, if the development team
likes the new technology, they can demonstrate the application
to the decision makers and sys admins to show the value of the
novel technology.
