PaaS (Platform as a Service)

is comparable to renting servers from large data centres. The "rented server" is yours to do with as you please so you can put any stack you want on the platform. In the case of Fedorazon we have used a LAMP like stack but with the software (SW) component being FedoraCommon's Java software base. Currently we would define examples of PaaS to include: AWS's EC2, IBM's Blue Cloud and perhaps even GoogleApp Engine once it has more SW stack component options.
