From security to assurance in the cloud: a survey

The cloud computing paradigm has become a mainstream solution for the deployment of business processes and applications. In the public cloud vision, infrastructure, platform, and software services are provisioned to tenants (i.e., customers and service providers) on a pay-as-you-go basis. Cloud tenants can use cloud resources at lower prices, and higher performance and flexibility, than traditional on-premises resources, without having to care about infrastructure management. Still, cloud tenants remain concerned with the cloud's level of service and the nonfunctional properties their applications can count on. In the last few years, the research community has been focusing on the nonfunctional aspects of the cloud paradigm, among which cloud security stands out. Several approaches to security have been described and summarized in general surveys on cloud security techniques. The survey in this article focuses on the interface between cloud security and cloud security assurance. First, we provide an overview of the state of the art on cloud security. Then, we introduce the notion of cloud security assurance and analyze its growing impact on cloud security approaches. Finally, we present some recommendations for the development of next-generation cloud security and assurance solutions

On the management of cloud non-functional properties : the cloud transparency toolkit

The cloud computing paradigm supports a vision of IT where virtual resources are distributed as commodities on either a subscription or a pay-per-use price model, without the need for any upfront investment in hardware or software assets for its tenants (i.e., customers and service providers). Since these resources, as well as data and applications moved to the cloud, are no longer directly controlled by their owners under tenancy, there is an increasing need for new solutions that reduce the uncertainty of tenants about the status of their data and applications in the cloud. In this paper, we present the architecture of the Cloud Transparency Toolkit (CTT), whose goal is to provide a general purpose and interoperable approach that increases the transparency of the cloud, improving the effectiveness of non-functional property verification and management

Fatigue life modelling under variable amplitude multiaxial loading: Comparison between fatigue criterion and incremental modelling

International audienceThis study deals with fatigue of a 1045 carbon steel subjected to a cyclic tension-torsion spectrum combining in-phase and out-of-phase loadings and including overload, representative of an automotive chassis loading type. The experimental lifetimes are compared to the results of two different approaches. The first one combines a multiaxial fatigue criterion able to describe out of phase loading and a non-linear damage rule. The second one is based on an incremental mesoscale plasticity/damage model. It is shown that the criterion involving a non-linear damage rule is able to describe the experimental result for full spectrum (with overload) but the identification of the non-linearity is a function of spectrum type. The incremental approach gives better results for both spectra (with and without overloads) and does not need specific parameter identification
