Cloud computing – running large-scale computationand data-intensive services on inexpensive onthe-fly clusters – has become increasingly popular in recent years due to the advent of MapReduce and similar large-scale data parallel systems. Cloud provisioning, i.e., allocating resources for cluster requests, is the first step toward instantiating such clusters. In this report, we formally define ...

This paper presents a dynamic Service Level Agreement (SLA) negotiation scheme between peer autonomous systems (ASes) that implement DiffServ per domain behaviors. For concreteness, we tailor our scheme to account for the needs of VoIP transport across multiple ASes. We present a heuristic but computationally simple and distributed scheme that uses traffic statistics to forecast the near-future...

This paper presents the results related to the development of a flexible domain-based access control infrastructure for distributed Grid-based Collaborative Environments and Complex Resource Provisioning. The paper proposes extensions to the classical RBAC model to address typical problems and requirements in the distributed hierarchical resource management such as: hierarchical resources polic...

A virtual machine, which is a software layer representing an execution environment, can be placed inside another virtual machine. As virtual machines at every level in a location hierarchy compete with other processes for processing time, the computing power of a virtual machine depends on its position in this hierarchy and may change if the virtual machine moves. These effects of nested virtua...

Cloud Computing allow the users to efficiently and dynamically provision computing resource to meet their IT needs. Companies are able to rent resources from cloud for storage and other computational purposes so that their infrastructure cost can be reduced. Further they can make use of company-wide access to applications based on pay-as-you-go model. Hence there is no need for getting licenses...

Cloud computing has gained significant popularity over past few years. Employing service-oriented architecture and resource virtualization technology, cloud provides the highest level of scalability for enterprise applications with variant load. This feature of cloud is the main attraction for migration of workflows to the cloud. Since each task of a workflow requires different processing power...

We present a policy-based, agent-enhanced resource provisioning architecture, which facilitates flexible and quantitative end-to-end bandwidth reservation and management on a per-user, per-application or per-flow basis. Based on this architecture, various session level Service Level Agreement (SLA) negotiation schemes involving bandwidth allocation, service start time, guaranteed session durati...

Transformers and storage systems in the electrical grid must be provisioned or sized just as routers and buffers must be sized in the Internet. We prove the formal equivalence between these two systems and use this insight to apply teletraffic theory to sizing the electrical grid, obtaining the capacity region corresponding to a given transformer and storage size. We conduct a fine-grained meas...

Cluster computing is excellent for parallel computation. It has become increasingly popular. In cluster computing, a service level agreement (SLA) is a set of quality of services (QoS) and a fee agreed between a customer and an application service provider. It plays an important role in an e-business application. An application service provider uses a set of cluster computing resources to suppo...

Although cloud computing has gained sufficient popularity in the last two years, there are still some key impediments to enterprise adoption. Cloud management is one of the top challenges. The ability of on-the-fly partitioning hardware resources into virtual machine(VM) instances facilitates the cloud to provide elastic computing environment to users. But the flexibility of resource provisioni...
