Hybrid Cloud Computing: Security Loopholes
Abstract
Cloud Computing has developed a strong place for itself in both business and Information Technology. Hybrid Cloud is a fusion of public and private cloud model, since it offers better cost benefits and services the adaption has been raising quickly. Regardless of the advantages, the hybrid cloud is susceptible to various Security problems related with cloud standardization, multi-tenancy, data governance risk and control, sudden service disruptions and the service level agreements. This paper emphasizes on the limitations and security loopholes in the Hybrid Cloud Computing model and suggests possible ways to mitigate the security risks.

Cloud Computing has an expanding future in both business and Information Technology. With the expanding hybrid cloud model offering better services and convenience there are also a number of security problems associated with cloud standardization, multi-tenancy third party privity/sub-contracting, data-controller, outages, availability, monitoring and the service level agreements. This paper focuses on Hybrid Cloud Computing security in the context of a Tenant-Vendor-Third-Party environment and service level agreements. Limitations, opportunities and suggestions to mitigate the security risks are discussed and summarized.
Resources management facilities, based on service level agreements, are needed in the Cloud in order to negotiate a collection
of inter-connected and virtualized computers between resource providers and consumers. In this paper we present the architectural
design of a system named Cloud Agency which aims to respond to this need and to offer added value to the existing Cloud services. This system is in charge to broker
the collection of Cloud resources from different providers that fulfills at the best the requirements of user’s applications.
The user is able to delegate to the Agency the necessary checks of the agreement fulfilment, the monitoring of resource utilization
and eventually necessary re-negotiations.
The primary purpose of this book is to capture the state-of-the-art in Cloud Computing technologies and applications. The book will also aim to identify potential research directions and technologies that will facilitate creation a global market-place of cloud computing services supporting scientific, industrial, business, and consumer applications. We expect the book to serve as a reference for larger audience such as systems architects, practitioners, developers, new researchers and graduate level students. This area of research is relatively recent, and as such has no existing reference book that addresses it. This book will be a timely contribution to a field that is gaining considerable research interest, momentum, and is expected to be of increasing interest to commercial developers. The book is targeted for professional computer science developers and graduate students especially at Masters level. As Cloud Computing is recognized as one of the top five emerging technologies that will have a major impact on the quality of science and society over the next 20 years, its knowledge will help position our readers at the forefront of the field.
With the significant advances in Information and Communications Technology (ICT) over the last half century, there is an increasingly perceived vision that computing will one day be the 5th utility (after water, electricity, gas, and telephony). This computing utility, like all other four existing utilities, will provide the basic level of computing service that is considered essential to meet the everyday needs of the general community. To deliver this vision, a number of computing paradigms have been proposed, of which the latest one is known as Cloud computing. Hence, in this paper, we define Cloud computing and provide the architecture for creating Clouds with market-oriented resource allocation by leveraging technologies such as Virtual Machines (VMs). We also provide insights on market-based resource management strategies that encompass both customer-driven service management and computational risk management to sustain Service Level Agreement (SLA)-oriented resource allocation. In addition, we reveal our early thoughts on interconnecting Clouds for dynamically creating global Cloud exchanges and markets. Then, we present some representative Cloud platforms, especially those developed in industries, along with our current work towards realizing market-oriented resource allocation of Clouds as realized in Aneka enterprise Cloud technology. Furthermore, we highlight the difference between High Performance Computing (HPC) workload and Internet-based services workload. We also describe a meta-negotiation infrastructure to establish global Cloud exchanges and markets, and illustrate a case study of harnessing ‘Storage Clouds’ for high performance content delivery. Finally, we conclude with the need for convergence of competing IT paradigms to deliver our 21st century vision.
