education of cloud engineers will be crucial for the continued development technologies. We have developed an open-source software platform called edubase Cloud education. The has multi-cloud architecture. In this paper, we discuss how provides alterable and effective it is educating engineers.

A new context aware access control architecture called Anonymous Context Aware Access Control Architecture (ACA2) is proposed. The basic idea of this based on an analogy to the public telephone service. users can use services supported by their information through preregistered software components proxies. main features include anonymity, suspension caused changes, and active certificates with stream verification.

Cloud computing environments have certain techniques to make applications auto-scale according the load. The environment is also used for disaster recovery. For instance, may allow move other cloud in event of disasters. Some applications, like continuous integration tests, need execution that depend on their test running context. Currently, these application types are treated individually development. However, they can be developed as self-deployable and Cluster a Service foundation...

Science computing platforms are changing from traditional on-premises to clouds. The style of research publications is also with the movement open science. For example, it common that researchers in bioscience community publish their papers associated data on Internet. Furthermore, demands for reproducibility computational experiments increasing. A conventional method, or sharing source codes application programs, not enough guarantee experiments. In this paper, we propose overlay cloud...

Education for cloud engineers is crucial in terms of innovation the development technologies. We propose a new platform based on open-source software that uses multi-clouds education.

High-performance R&E networks and clouds enable the construction of a secure virtual cloud environment over their resources. However, it is not easy for general users to construct such an build application environment, as this would require each user only have knowledge about target application, but also APIs resource optimization. This prompted us propose Virtual Cloud Service System (VCSS), which allows academic application-specific environment. The system consists Provider (VCP)...

As learning management systems (LMSs) become increasingly popular in many universities, large scale Moodle systems, such as cross-university LMSs, have been implemented, and they accumlate a amount of LMS log data. To handle data, it is effective to use cloud computing environment. However, because data contain much personal information, often necessary anonymise or pseudonymise the them In this study, we implemented analysis environment that combines an organisation's internal server by...

We propose an extension of distcloud-fs for achieving a global distributed POSIX file system in intercloud environment. The works environment, that is, on the top multiple independent cloud services. important capability is there no need users to take care infrastructure layer, while stores data into services, transparently and automatically. As result, may have diversity about vendors locations platform, as discussed various research projects. In this paper, we describe architecture its...

This study describes a trial for determining cloud architecture science applications. For scientific applications that need huge amounts of remotely stored data, the infrastructure has functionalities to provide serviced called 'cluster as service,' and inter-cloud object storage service. The move locations where data or other location constrained resources by which calculation speed becomes practical are.

For scientific applications that need huge amounts of remotely stored data, the cloud infrastructure has functionalities to provide service called `cluster as service' and an inter-cloud The move from locations with constrained resources where they can be executed practically. in order perform well.

Mobile computing environments are being realized by the rapid popularization of cellular phones and miniaturization performance enhancement mobile terminals. However, several technological issues still a problem, such as narrow bandwidth wireless communications, limited battery duration terminals, etc. Moreover, it is difficult to develop application programs that operate in because complicated procedure communications. This paper proposes common memory management mechanism for terminals...

Through this study, we aim to examine a method for data integration in shared Learning Management System (LMS) authentication federation. We proposed of transmitting ePTID and learning with user's consent as across institutions. The is compared the other existing methods realize LMS. discuss suitable next version GakuNinMoodle conclude that our requirements are not fully satisfied by single method.

Two basic approaches have been proposed to deal with cloud burst, disaster recovery, business continuity, etc., in community clouds: standardization of services and multi-cloud federation. The approach would take time; i.e., it not be effective until there are enough implementations deployments following the standard specifications. federation places limitations on functionalities provided users; they greatest common divisor cloudsâ?? functions. Our is â??cloud demandâ??, which means...

Cluster computing has become popular in academia and industry. Clusters of commodity servers are used for a variety distributed applications like simulation, data analysis, web services. No single framework can fit every application. Even an Infrastructure as Service (IaaS) the Openstack cloud cannot all them because, example, some researchers would likely want to deploy hadoop clusters on bare metal servers. One solution this problem is assign layer below IaaS/PaaS (Platform Service) job...
