A Generalized Service Replication Process In Distributed Environments, Hany F. Elyamany, Marwa F. Mohamed, Katarina Grolinger, Miriam Am Capretz

Electrical and Computer Engineering Publications

Replication is one of the main techniques aiming to improve Web services’ (WS) quality of service (QoS) in distributed environments, including clouds and mobile devices. Service replication is a way of improving WS performance and availability by creating several copies or replicas of Web services which work in parallel or sequentially under defined circumstances. In this paper, a generalized replication process for distributed environments is discussed based on established replication studies. The generalized replication process consists of three main steps: sensing the environment characteristics, determining the replication strategy, and implementing the selected replication strategy. To demonstrate application of the generalized …

Evaluating Single Sign On Security Failure In Cloud Services, Brian Cusack, Eghbal Zadeh

Australian Information Security Management Conference

The business use of cloud computing services is motivated by the ease of use and the potential financial cost reductions. Service failure may occur when the service provider does not protect information or when the use of the services becomes overly complex and difficult. The benefits also bring optimisation challenges for the information owners who must assess the service security risk and the degree to which new human behaviours are required. In this research we look at the risk of identity theft when ease of service access is provided through a Single Sign On (SSO) authorisation and ask: What are …

Cloud Computing:Strategies For Cloud Computing Adoption, Faith Shimba

Dissertations

The advent of cloud computing in recent years has sparked an interest from different organisations, institutions and users to take advantage of web applications. This is a result of the new economic model for the Information Technology (IT) department that cloud computing promises. The model promises a shift from an organisation required to invest heavily for limited IT resources that are internally managed, to a model where the organisation can buy or rent resources that are managed by a cloud provider, and pay per use. Cloud computing also promises scalability of resources and on-demand availability of resources.

Although, the adoption …
