Cloud environment consists of many components playing different roles which need to interact with each other. Based on the context the nature of interaction may vary. Trust is an essential facet for confidence-based interactions among the various entities in cloud environment. This paper presents the taxonomy of trust models and classification of information sources for trust assessment in cloud paradigm...
With the increase in number of mobile devices deployed in cloud computing, the demand of context-aware services to assign increases. Indeed, Information about the user's environment exposes new challenges to cloud computing in terms of location-aware, time-aware, device-aware and personalized applications to cope with the constraints of mobile devices in matters of interaction abilities and communication...
The number of web services has been increased rapidly and thereby discovering the services in cloud computing has become a challenge for the service consumers. As a result, Service discovery and mapping have become even more challenging due to different service descriptions, conventions, heterogeneous types and features of Cloud services. Service discovery has been identified as a key activity for...
With the evolution of service computing ecosystems and the promises of the Cloud, there is an increasing need for service evaluation and monitoring across a wide range of QoS dimensions. Although in the literature service monitoring is tightly coupled with Service Level Agreement establishment, existing approaches do not provide a holistic model for Cloud service evaluation. In this paper, we present...
Cloud storage has recently appeared as a promising solution to handle the immense volume of data produced in nowadays' rich and ubiquitous digital environment. Existing approaches, however, do not fully address certain significant issues, such as Service Level Agreements, which tend to be rudimentary, and management of cloud systems, which often lacks sophistication. In this paper, we propose the...
Cloud computing is an emerging paradigm able of flexibly offering IT resources and services over the Internet. Cloud computing's high flexibility needs novel software engineering approaches, and technologies to deliver agile, flexible, scalable yet secure software solutions with full technical (e.g. QoS, service continuity etc.) and business gain (e.g. profit, corporate value, utility etc.). Agile...
The cloud computing model aims to make large-scale data-intensive computing affordable even for users with limited financial resources, that cannot invest into expensive infrastructures necesssary to run them. In this context, MapReduce is emerging as a highly scalable programming paradigm that enables high-throughput data-intensive processing as a cloud service. Its performance is highly dependent...
A Cyber-Physical System (CPS) is defined as integrations of computation and physical processes. In CPS, downsized embedded devices monitor and manage the physical process. Mobile Internet Device (MID), as a portable handheld device designed for mobility providing a down-graded computing capability, can be used as a strong candidate for client-side devices in CPS. Since these physical devices have...
