The Cloud Computing is emerging as a new computing paradigm where in scalable and virtualized resources it is provided as a service to the user. It employs a model for enabling available, convenient and on-demand network access to a shared pool of configurable computing resources like networks, servers, storage, software, applications and services that can be rapidly provisioned and released with minimal management effort. There are many vendors who provide cloud services. In this thesis based work, Aneka, Hadoop, and Flink platforms are explored for various experimental purposes. As fast access of data from the cloud is a major challenge, this book explores many existing literature sources to develop better architectures and algorithms for efficient data access from cloud.
