Study of Cloud Computing and Survey of PaaS and SaaS Providers

With the booming computational world, it is becoming complex. Cloud computing emerged as a new platform for the computation and processing of the data elsewhere. However, there is no standardised definition for cloud computing. People often get confused between distributed and cloud computing. Major companies like Oracle, Amazon and Google have introduced the cloud practically and are using the pay-for-use models, thereby earning billions. We will try to define the cloud and will survey various providers, not to find the similarities and differences, but to help for the better development of the cloud.
