This publication summarizes the 2011 volume contents of International Journal of Cloud Applications and Computing (IJCAC) that addresses current trends in Cloud Computing, such as Cloud services, applications, and technologies. To illustrate the role of applications and services in the growth of Cloud computing industries, a number of examples focusing on the learning, government, and security ...

AppScale is a scalable, distributed, and fault tolerant cloud runtime system that we have developed at the University of California, Santa Barbara as part of our research into the next generation of programming systems [5, 3]. In particular, AppScale is a cloud platform, i.e. a platform-as-a-service (PaaS) cloud fabric, that executes over cluster resources. The cluster resources underlying AppS...

Cloud computing is a promising computing paradigm wherein the resources are made available to the clients as services, over high bandwidth networks. Cloud SaaS refers to a cloud computing service model in which the software applications are offered as services. These cloud software applications may require interacting with each other in order to accomplish a task. Thus, interoperability among s...

The paper presents the vulnerabilities of cloud storage and various possible attacks exploiting these vulnerabilities that relate to cloud security, which is one of the challenging features of cloud computing. The attacks are classified into three broad categories of which the social networking based attacks are the recent attacks which are evolving out of existing technologies such as P2P file...

In recent years there has been rapid growth in cloud computing and social networking technologies. Cloud computing shifts the computing resources to a third party, eliminating the need to purchase, configure and maintain those resources. With the incentive of lowered operational costs in software, hardware and human effort, many companies are considering the use of cloud services. Likewise, soc...

Cyber threats against clouds have evolved rapidly. Traditional reactive cyber defense technologies are not effective and sufficient to protect federated clouds. This chapter introduces the novel federated cloud security architecture that includes proactive cloud defense technologies for secure and agile cloud development. The federated security architecture consists of a set of seamlessly integ...

Cloud Computing has recently emerged as a compelling paradigm for managing and delivering services over the internet. The rise of Cloud Computing is rapidly changing the landscape of information technology, and ultimately turning the longheld promise of utility computing into a reality. As the development of Cloud Computing paradigm is speedily progressing, concepts, and terminologies are becom...

Technologies have become inseparable of our lives, economy, and the society as a whole. For example, clouds provide numerous computing resources that can facilitate our lives, whereas the Content Management Systems (CMSs) can provide the right content for the right user. Thus, education must embrace these emerging technologies in order to prepare citizens for the 21 st century. The research exp...

The term big data arose under the explosive increase of global data as a technology that is able to store and process big and varied volumes of data, providing both enterprises and science with deep insights over its clients/experiments. Cloud computing provides a reliable, fault-tolerant, available and scalable environment to harbour big data distributed management systems. Within the context ...

This paper discusses the construction and a logical aggregation method of multi-access link manufacturing cloud core networks. The key technologies involved in the logical aggregation of multi-access link manufacturing cloud core networks are discussed in detail. Focusing on the key technologies including access load scheduling, access link flow monitoring, link aggregation control, and gateway...
