Recently, we have witnessed numerous benefits ofexploiting Cloud Computing models and technologies in thecontext of the Internet of Things and Edge Computing. However, utility-based provisioning paradigm, one of the most importantproperties of Cloud Computing, is yet to be realized in emergingIoT Cloud systems. In this paper, we introduce a novel middleware, which provides comprehensive support for...
Raw sensed data lacks semantics. This poses a challenge to apply analytics directly to raw IoT sensor data. Such operational data requires an intensive enrichment processes to drive value. Pragmatic use of naming conventions and taxonomies can increase the quality of data and make it more interpretable. In this paper, we incorporate semantic and linked data technologies and offer a middleware called...
A core idea of cloud computing is elasticity, i.e., enabling applications to adapt to varying load by dynamically acquiring and releasing cloud resources. One concrete realization is cloud bursting, which is the migration of applications or parts of applications running in a private cloud to a public cloud to cover load spikes. Actually building a cloud bursting enabled application is not trivial...
Cloud computing represents a promising computing paradigm, where computational power is provided similar to utilities like water, electricity or gas. While most of the Cloud providers can guarantee some measurable non-functional performance metrics e.g., service availability or throughput, there is lack of adequate mechanisms for guaranteeing certifiable and auditable security, trust, and privacy...
