There is a quite a lot of development in PaaS (Platform as a Service) and SaaS (Service as a Service) in the fields of Cloud Computing. However I was thinking of a scenario where
An end user/ firm would actually like to hire some things which do sensing in an environment (Industrial, Environmental) which the end user need not have. Hence, perhaps something like Thing as a Service (TaaS)
The only closest thing that I can relate to this is Testbeds where you can conducts tests and experiments but I am looking whether, there might be some Commercial solutions too for this "concept".
