As cloud computing industry adoption rate is increasing, service cost management and optimization are becoming one of the most important issues from the perspective of cloud users. This paper is looking into possibility of using information about application type and its resource usage profile in the process of identifying optimized service placement in cloud environments. Such placement should result...
With the development of cloud technology, cloud computing has been increasingly used as distributed platforms for multimedia services. However there are two fundamental challenges for service providers: one is resource allocation, and the other is workload scheduling. Due to the rapidly varying workload and strict response time requirement, it is difficult to optimally allocate virtual machines (VMs)...
An I/O intensive application is one of the most common applications in cloud computing, which is a dominant type in some occasions. However, few studies have focused on how to improve the processing efficiency of such specific type of applications. We have found out the performance bottlenecks based on the features obtained from I/O-intensive applications. By analyzing the features of files, we put...
With the development of cloud computing, datacenter already plays increasingly important role in improving the multimedia user Quality of Experience (QoE). The resource allocation strategy, namely the virtual machines (VMs) allocation strategy, is a major research direction for cloud computing technology. In this paper, we introduce the definition of near-client-datacenter for virtual machines, which...
In last decayed a big revolution has been done in the communication and network industry and in presence scenario cloud computing has been playing a significant role for last one year. Since user or client preferred flexibility to acquired any network on the basis of bandwidth, QoS (Quality of service) and Cost i.e. cost should be proportional to demand and uses of data. In this paper we have given...
Nowadays, the cloud computing ecosystem is more and more distributed and heterogeneous. Cloud service providers begin to build their services using cloud-based services offered by other service providers. This raises several issues due to integration between services and provider themselves. In this paper, we propose a practice addressing such a concern in a "Vertical Supply Chain" scenario...
