-The Cloud computing offers dynamically scalable resources provisioned as a service over the Internet. It enables individuals and organization to use various services like software as a service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service(IaaS) over the Internet. Virtualization is the fundamental technology that powers cloud computing. Virtualization allows running multi...

Frühjahrstreffen 2013 der Fachgruppe Betriebssysteme Steffen Kächele and Franz J. Hauck Institute of Distributed Systems University of Ulm, Germany {steffen.kaechele,franz.hauck}@uni-ulm.de Introduction Platform as a service (PaaS) is a cloud service model that supports a very high abstraction to tenants. Application developers have to use a certain programming model, e.g. Web Servlets, offered...

Current Cloud solutions for Edge Computing are inefficient data-centric applications, as they focus on the IaaS/PaaS level and miss data modeling operations perspective. Consequently, opportunities lost due to cumbersome assets-agnostic processes end-to-end deployment over Cloud-to-Edge continuum. In this paper, we introduce MEDAL—an intelligent Data Fabric support Operations (DataOps) across c...

Context-awareness enables systems to be tailored the needs of users and their real circumstances at certain times. A noteworthy trend in software development is that an increasing number are being developed by individuals with expert knowledge other sectors. Because most current context-aware toolkits intended for developers, these types cannot easily non-technical consumers. The tools designin...

Cloud computing has recently emerged as a new computing paradigm. This latter provides provisioning of dynamically scalable and often virtualized resources which are offered as services. In this context, there is a services pool that supports platforms and mechanisms in order to guarantee the applications development and execution. This set of services is called platform as a service (PaaS). On...

Nowadays many applications must process events at a very high rate. These events are processed on the fly, without being stored. Complex Event Processing technology (CEP) is used to implement such applications. Some of the CEP systems, like Apache Storm the most popular CEPs, lack a query language and operators to program queries as done in traditional relational databases. This paper presents ...
