In cloud environments, trust is necessary because services have the characteristics of uncertainty, dynamic, false or fraudulent which usually make users difficult to obtain desired services. In this paper, we consider trust-oriented workflow scheduling with temporal constraints including service setup times and workflow deadlines. The considered problem is mathematically modeled. A behavior-based...
by virtual machines and the reduce of resource utilization caused by migration of a single virtual machine in cloud computing , this paper proposes a load balancing strategy based on data correlation in cloud computing. This strategy finds out the migration unit based on the correlation between the data and the virtual machines used to deal with the same data, and construct the load-intensive data...
Cloud computing has bloomed as a huge research area in many ways to be made more scalable and secure. One of the major issues that this technology is battling is to provide quick and high quality service to the consumers by placing a service request to the cloud. Many algorithms have been suggested to provide an algorithm for scheduling these requests in such a way that the various QoS parameters...
As more and more cloud services are provided on the web, composite services will increase exponentially. How to select the optimal services for a given composite service is a important problem and is NP-Hard. This paper proposes a multi-objective service selection algorithm based on MOACS(Multi-Objective Ant Colony System) optimization algorithm for this problem. In this problem, two objectives are...
Executing a large number of workflow applications within their deadlines and efficient utilization of computing resources in a cloud computing environment is a challenging problem. A workflow application is usually represented as a set of tasks interconnected via data. In most of the scheduling algorithms, the execution times of the tasks are pre-computed. However, the execution time of the tasks...
The data centers of cloud video surveillance (CVS) systems based on Hadoop have a couple of common problems such as large energy consumption, low power utilization, etc. Addressing to the issue of reducing energy consumption while guaranteeing quality of service, we propose an energy-aware workload balancing method for efficient data storage management in cloud video data centers. A dynamic adjusting...
Dynamic multi-resource fair allocation became an important topic for cloud resource management. We consider a generalized version of the dynamic multi-resource fair allocation problem, where an agent is satisfied when all tasks it submitted can be processed. We design a generalized dynamic dominant resource fairness mechanism, and develop a combinatorial algorithm to find a fair allocation. Experimental...
The ever-growing demand for cloud resources places the resource management at the heart of the design and decision-making processes in cloud computing environments. Cloud providers offer heterogeneous resources such as CPUs, memory, and storage in the form of Virtual Machine (VM)instances. Recently, cloud providers have introduced auction-based models to sell their unutilized resources in an auction...
The scale and complexity of online applications and e-business infrastructures has led service providers to rely on the capabilities of large-scale hosting platforms, i.e., data centers. Dynamic resource allocation (DRA) algorithms have been shown to allow server resource allocation to be matched with application workload, which can improve server resource utilisation and drive down costs for service...
Cloud computing and IT-service provisioning is critical for the growth of enterprises in being able to provision computationally intensive applications. A high-speed networks infrastructure is necessary for the proliferation of cloud computing to meet disparate IT application demands. Light-trails - a generalization of lightpath with ability to provision sub-wavelength demands, meet dynamic bandwidth...
Light-trail, a spatial sub-wavelength optical grooming solution for WDM networks, facilitates dynamic bandwidth provisioning and optical multicasting - essential for cloud computing services. We evaluate through simulations a novel protocol for cloud computing over light-trails.
