Cloud manufacturing is a new paradigm which has been under study since 2010 and a vast body of research has been conducted on this topic. Among them, service composition problems are of utmost importance. However, most studies only focused on private clouds meaning the objective function is defined for just one component of the supply chain. This paper attempts to consider service composition p...

Cloud Computing, the emerging technology, delivers IT capabilities as services-on-demand using internet. Though the Cloud technology possesses lot many benefits, it suffer several challenges which hinders the adoption of public cloud by many organizations. Since the consumer has to depend on the cloud provider’s infrastructure that is not completely controlled internally by the consumer, the ma...

Hybrid cloud technology is becoming increasingly popular as it merges private and public clouds to bring the best of two worlds together. However, due to the heterogeneous cloud installation, facilitating a hybrid cloud setup is not simple. Despite the availability of some commercial solutions to build a hybrid cloud, an open source implementation is still unavailable. In this paper, we try to ...

1.1 Introduction Clouds typically have highly dynamic demands for resources with highly heterogeneous and dynamic workloads. For example, the workloads associated with the application can be quite dynamic, both in terms of the number of tasks processed as well as computation requirements of each task. Furthermore, different applications may have very different and dynamic QoS requirements, for ...

Cloud computing has elevated IT to newer limits by offering the market environment data storage and capacity with flexible scalable computing processing power to match elastic demand and supply, whilst reducing capital expenditure. However the opportunity cost of the successful implementation of Cloud computing is to effectively manage the security in the cloud applications. Security consciousn...

The Massachusetts open cloud is a new non-profit open public cloud that will be hosted (primarily) at the MGHPCC data center. Its mission is to accelerate innovation in and broaden the applicability of cloud computing. In creating an open alternative to today’s public clouds, the MOC will create an environment that will foster innovation, job creation, new companies and industries, and more res...

In this paper, we have considered a Markovian bulk-service queue for cloud computing architecture. The multiple class i users from the public cloud entering into the queue are naturally based on the FCFS discipline. Partial batch service mode and full batch service mode have considered for accessing cloud database. The requesting and service of the public cloud has been modelled using queueing ...

Cloud computing has been popular as the IT architectures. Cloud service providers offers many services based on cloud computing. Cloud storage service is one of the cloud services which can provide a huge storage space to solve the bottleneck of the storage space of local end users. Here the Cloud server allows the users to store their data on cloud without worrying about correctness and integr...

Businesses today must maintain a laser-like focus on containing costs and increasing efficiencies in every possible way in order to generate profits and maintain competitiveness. Supply chain management (SCM) & optimization is a critical aspect of modern enterprises and an ever-green research area. IT dept plays a major role in the optimization of supply chains. This paper presents a critical r...

Organizations owning a datacenter and leasing resources from public clouds need to efficiently manage this heterogeneous infrastructure. In order to do that, automatic management of processing, storage, and networking is desirable to support the use of both private and public cloud resources at the same time, composing the so-called hybrid cloud. In this chapter, the authors introduce the hybri...
