Today i learnt about the three service models of cloud computing.These models are laaS,PaaS,PaaS.The models can be best understood by taking an example.what will we do if we go to a new place and need an accommodation.We can build a new house,live in a hotel,buy a new house.Building a new house is similar to laaS,buying a new house is like PaaS,living in a hotel is like SaaS.Treatment of computer programs as products or as services decide the economics of the software.Software should be reproducible ,replicable,reusable and it can be copied.laaS can be thought as copying of hardware,PaaS can be viewed as copying of apllication software.PaaS is delivery of a computing platform over the web.
