Cloud Computing is rapidly emerging as the new information technology platform. It is, however, much more than simply a new set of technologies and business models. Cloud Computing is transforming how consumers, companies, and governments store information, how they process that information, and how they utilize computing power. It can be an engine of innovation, a platform for entrepreneurship...

Cloud computing allows users to perform computation in a public cloud with a pricing scheme typically based on incurred resource consumption. While cloud computing is often considered as merely a new application for classic distributed systems, we argue that, by decoupling users from cloud providers with a pricing scheme as the bridge, cloud computing has fundamentally changed the landscape of ...

Big data applications are constructed under the cloud environment to process the big data values. Public cloud provides easily scaled up and scaled down computing power and storage to everyone. Private cloud services are provided to group of people only. Big data can be used in disaster management, high energy physics, genomics, connectomics, automobile simulations and medical imaging applicati...

With the emergence of cloud computing technology and its ability to provide various services at affordable prices has become an important catalyst for many organizations to outsource their data to public cloud. The data owners might allow other users to gain access to their data. In this context, it is important to provide end to end data security to data. In this paper, our focus was on buildi...

In the last few years, cloud computing has evolved from a buzzword to a critical infrastructure component of many enterprise and consumer services. The cloud provides virtually limitless compute, storage and network resources at low cost, allowing services to scale on demand. The cloud absolves organizations from managing IT infrastructure, and allows them to focus on their core competencies. H...

In cloud storage service, public auditing mechanisms allow a third party to verify integrity of the outsourced data on behalf of data users without the need to retrieve data from the cloud server. Recently, Shen et al. proposed a new lightweight and privacy preserving cloud data auditing scheme which employs a third party medium to perform time-consuming operations on behalf of users. The autho...

Cloud storage could be a storage of information on-line in cloud that is accessible from multiple and connected resources. Cloud storage will offer smart accessibility and reliability, sturdy protection, disaster recovery, and lowest price. Cloud storage having vital practicality i.e. securely, with efficiency, flexibly sharing information with others. New public–key cryptography that is named ...

Aneka is an Application Platform-as-a-Service (Aneka PaaS) for Cloud Computing. It acts as a framework for building customized applications and deploying them on either public or private Clouds. One of the key features of Aneka is its support for provisioning resources on different public Cloud providers such as Amazon EC2, Windows Azure and GoGrid. In this chapter, we will present Aneka platfo...
