Cloud computing provides a revolutionary model for the deployment of enterprise applications and Web services alike. In this new model, cloud users save on the cost of purchasing and managing base infrastructure, while the cloud providers save on the cost of maintaining underutilized CPU, memory, and network resources. In migrating to this new model, users face a variety of issues. Commercial c...

Infrastructure as a Service (IaaS) is one of the provisioning models for Clouds as defined in the NIST Clouds definition. Although widely used, current IaaS implementations and solutions doesn’t have common and well defined architecture model. The paper attempts to define a generic architecture for IaaS based on current research by authors in developing novel architectural framework for Infrast...

To satisfy demanding clients and o↵er features comparable to the competition, infrastructure-as-a-service providers (IaaS) need fast, flexible and easily configurable local networks. OpenStack is one of the most well known open IaaS platforms. Although OpenStack meets most needs of a IaaS platform, its virtualized network implementation still lacks flexibility to support isolation on a multi-te...

Developing and deploying Service-based Applications (SBAs) using different Software-as-a-service (SaaS), Platform-as-a-service (PaaS) and Infrastructure-as-a-service (IaaS) offerings from multiple providers in the cloud is still not possible, since current cloud service offerings are often provided as monolithic, one-size-fits-all solutions and give little or no room for customization. This lim...

Scientific computing endeavors have created clusters, grids, and supercomputers as high performance computing (HPC) platforms and paradigms. These resources focus on peak performance and computing efficiency, thereby enabling scientific community to tackle non-trivial problems on massively parallel architectures. Meanwhile, efforts to leverage the economies of scale from data center operations ...

Infrastructure as a Service (IaaS) provides a developer the ability to construct applications that dynamically acquire and release potentially large numbers of raw virtual or physical machines (nodes). The Elastic Building Block Runtime (EbbRT) is a new runtime for constructing and retro-fitting applications to take advantage of this opportunity. EbbRT is a realization of the MultiLibOS model[?...

The cloud computing model transforming the IT landscape. Cloud computing is a new computing paradigm that delivers computing resources as a set of reliable and scalable internet allowing customers to remotely run and manage these services. Infrastructure-as-a-service (IaaS) is one of the popular cloud computing services. IaaS allows customers to increase their computing resources on the fly wit...

In Infrastructure as a Service (IaaS) environments, the user virtual machine is the user’s private property. However, in the case of privacy protection, how to ensure the security of files in the user virtual machine and the user virtual machine’s behavior does not affect other virtual machines; it is a major challenge. This paper presents a trusted measurement model based on dynamic policy and...
