A semantic interoperability framework for software as a service systems in cloud computing environments

Using Semantic Web Ontology for Intercloud Directories and Exchanges

The concept of a cloud operated by one service provider or enterprise interoperating with a clouds operated by another is a powerful idea. So far that is limited to use cases where code running on one cloud explicitly references a service on another cloud. There is no implicit and transparent interoperability. This interoperability should be more than cloud to cloud, it should embody 1-to-many ...

Semantic-based policy management for cloud computing environments

Cloud computing environments do not allow use of a single access control mechanism, single policy language or single policy management tool for various cloud services. Currently, users must use diverse access control solutions available for each cloud service provider to secure their data. Access control policies may be composed in incompatible ways because of diverse policy languages that are ...

Semantic Reasoning with Contextual Ontologies on Sensor Cloud Environment

This research first focused on processing enormous number of sensor events from a variety of city-wide sensor networks. As a solution, the well-known big data handling scheme, Hadoop cluster framework, drew, unquestionably, our attention.The acquired sensor events are to be used to immediately detect a certain abnormal situation within the framework. Accordingly, we integrated our existing cont...

Technical and Semantic Interoperability in the Cloud Broker

Cloud Computing represents an evolution of information systems. This technology is suitable for large groups but also for SMEs that offers a very high computing power at lower costs. It is used to interconnect several organizations disregarding their geographic location, and transforms current computer infrastructures and services. Cloud computing brings a new approach to computing, a different...
