The emergence of 5G wireless and IoT (Internet of Things) technologies, as well as the continuous evolution of cloud computing is driving the need for easy and on-demand creation of end-to-end network services. We have developed an integrated system called the end-to-end network service orchestrator, which realizes seamless service orchestration across multiple on-premises and cloud infrastructures...
Cloud database management systems (DBMSs) often decouple database instances from physical storage to provide reliability and high availability to users. This design can robustly handle a single point of failure, but needs substantial effort to attain good performance. In this paper, we analyze the decoupled architecture and present important optimization issues that we faced in implementing the design...
Internet-scale services increasingly rely on NoSQL data store technologies for scalable, highly available data persistence. To increase resource efficiency and deployment speed, such services are adopting new deployment models based on container technologies. Emerging container management systems (CMS) offer new models of interaction with containerized applications, exposing goal-oriented management...
Academic and industry experts are now advocating for going from large-centralized Cloud Computing infrastructures to smaller ones massively distributed at the edge of the network. Among the obstacles to the adoption of this model is the development of a convenient and powerful IaaS system capable of managing a significant number of remote data-centers in a unified way. In this paper, we introduce...
Day by day the use of memory is increases rapidly. A lot of data created every day so the data management is become a critical task. Most of time much amount of memory wastage because of same copies present on various locations. The process of eliminating the repeated or duplicates copies of data is called as Data deduplication. This data deduplication process is widely used in cloud storage to decrease...
Content Delivery Networks (CDN) interconnect several surrogate a.k.a replica servers that use geographical proximity as a criteria for delivering multimedia content. The delivered content may be enriched by value-added video services (e.g. in-stream video advertisements). The purpose of this demo is to show the prototype we developed in order to enable a cost-efficient and agile provisioning of value-added...
In the bygone, the exploration in computing focused on cloud computing, big data, and the internet of things (IOT). Irrespective of what computing is used, there is always a requirement for storage. The challenge faced in this area is storing the massive amount of data and their integrity. In the cloud, computing resources and services are made available on demand the most significant among them is...
Cloud providers seek to maximize their market share. Traditionally, they deploy datacenters with sufficient capacity to accommodate their entire compute demand while maintaining geographical affinity to its customers. Achieving these goals by a single cloud provider is increasingly unrealistic from a cost of ownership perspective. Moreover, the carbon emissions from underutilized datacenters place...
Enterprises that host services in the cloud need to protect their cloud resources using network services such as firewalls and deep packet inspection systems. While middleboxeshave typically been used to implement such network functions in traditional enterprisenetworks, their use in cloud environments by cloud tenants is problematic due to the boundary between cloud providers and cloud tenants. Insteadwe...
This paper describes a software system prototype for automated game servers deployment and configuring customized game servers on demand. The described system has a web interface which allows customers to create accounts, purchase, services, and gain access to and configure their purchased web servers. This service consists of a website which acts as an interface for customers to purchase subscriptions,...
Serious disasters have been annually occurred in Japan. Particularly, in the Great East Japan Earthquake that occurred on March 11, 2011, the communication infrastructure was seriously damaged over wide areas. Due to such situation, more resilient network infrastructure that does not stop under challenged communication environment is required. In this paper, we propose a disaster information system...
Lightweight virtualization, as implemented by application container solutions such as Docker, have the potential to revolutionize the way multi-tier applications are developed and deployed, especially in the cloud. The success of application containers can be partly attributed to their ability to share resources with the underlying platform that hosts them. As such, the isolation provided by such...
Recently diverse testbeds are built to experiment and verify new service ideas on SDN/Cloud-leveraged networking. In the early stage of verification, easy and speedy execution of experiments is required. Thus, in this paper, we introduce S-Box virtualized playground, where lightweight experiments are automatically executed only with the virtualized resources in a single box. The proposed S-Box concept...
We present an architecture that increases persistence and reliability of automated infrastructure management in the context of hybrid, cluster-cloud environments. We describe our highly available implementation that builds upon Chef configuration management system and infrastructure-as-a-service cloud resources from Amazon Web Services. We summarize our experience with managing a 20-node Linux cluster...
A smart evacuation needs a scalable and flexible system to provide service in both emergency and normal situations. A single cloud service is usually limited to support scaling up requirements in an emergency, especially one with a large geographic scope. In this article, the authors propose MCES, a multicloud architecture that deploys smart evacuation services in multiple cloud providers and that...
Object detection is one of the main challenges of cyber-physical systems for mobile applications. Mobile devices as embedded systems might not provide sufficient performance to meet the computational requirements for object detection, whereas it is not reasonable to enhance such devices with powerful processors. In this paper, we present a prototype system for mobile object detection based on smartphones...
How to establish a trusted framework in an untrusted environment is an important problem in many areas. So it is in the field of cloud service. It's also hard to find the balance between assuring security of the cloud users' privacy and keeping the usability and efficiency of the cloud service. This paper proposes a scheme of virtual data center, which works as a cloud-agent. We adopt two key technologies,...
The current financial situation, together with the new market conditions, has led to major changes in the ICT sector over the last few years. Many of the services that were once only offered by operators are now being provided by third parties through the cloud. This situation has promoted new business models against the traditional ones. Furthermore, these economic changes have conducted to socio-cultural...
In a virtualization environment that serves multiple tenants, storage consolidation at the filesystem level is desirable because it enables data sharing, administration efficiency, and performance optimizations. The scalable deployment of filesystems in such environments is challenging due to intermediate translation layers required for networked file access or identity management. First we present...
Medical imaging research deals with large, heterogeneous and fragmented amounts of medical images. Such challenges lead to the need for secure, federated and functional medical image storage within this research community. With limited IT professional and research fund, the community is better provided with an outsourcing arrangement. Cloud computing promises lower cost, high scalability and availability...
