摘要：Cloud computing has become the latest buzzword as this trend has revolutionized the field of computer science to greater heights. This paradigm of computing has bought down the onus of enterprises and end users by providing agility - not only to deploy applications more quickly but also to respond to changes in demand, focus – having people to focus on higher levels of stack rather than worrying about underlying infrastructure, and economics – pricing based on usage as this factor reduces the overall cost. The layers that provides services in cloud computing include infrastructure as the base layer, platform as the interface between applications and hardware and finally the top layer software being the front end with which the users interact. This paper can be regarded as a handout which gives a complete description of the layers. Illustrations corresponding to each layer such as Amazon Web Services (AWS), Google App Engine (GAE) and Microsoft Office 365 are provided for a better picture on the inner workings of the layers. This paper also contains a brief view on the architecture of cloud and deployment models, as it attempts to bring out the functioning of the each layer
