The IEEE Intercloud project aims to facilitate intercloud interoperability and portability. While topology elements and basic security and trust models had been developed during the last years, an adequate base protocol for the intercloud communication is still required. This protocol have to be extensible and should eliminate limitations of HTTP. This paper proposes a novel protocol that addresses...
Since the cloud paradigm becomes increasingly popular for dynamic resources allocation, the flexibility of a cloud is still limited regarding network services and their autonomous federation between different providers. The following architectural approach introduces a generic layered model to orchestrate and federate heterogeneous networks. In particular, an architecture is presented that enables...
Software Defined Networking decouples network services from the underlying physical hardware, thus agile and secure networks can be build, moved, replaced, and programmatically provided on demand. However, the full range of Software Defined Networking capabilities is not utilized in today's cloud middle wares, especially dynamic Quality of Service enforcement for cloud networks. In this paper we combine...
The management of today's service level agreements on the cloud market is often nontransparent and ineffective for the customer and the provider. However, service level agreements are crucial for establishing trust between all participants, especially for companies whose success depends on the purchased cloud service with its appropriated service quality. This paper introduces a concept for an Agreement-Mediator...
SaaS applications often face a vendor or technical lock-in due to PaaS provider specific specifications, like cloud management APIs. As a solution, this paper presents a novel approach for developing applications more PaaS provider independent. In particular, the approach illustrates advantages of extending JavaEE application servers with a new container that executes so called Infrastructure Java...
Mobile devices are becoming more powerful and are able to support applications of significant size and high processing efforts. However, most of the applications require mobile internet connections to use information and services of background infrastructures. Especially business applications for mobile devices consisting of a dashboard that provides the user with information and a service orientated...
Since the cloud paradigm becomes more and more popular for the dynamic resources allocation, new techniques and performance improvements for scalability as well as new cloud services on all three layers of the cloud stack were developed. Furthermore, another well covered topic is cloud federation concerning processing power and strength. However, the flexibility of the cloud is limited in terms of...
Cloud computing has already been adopted in a broad range of application domains and has become an established building block in IT landscapes. During the process of cloud middleware development, the companies have focused mainly on the high availability of data and end-user services, but unfortunately neglected the availability of middleware components. Therefore failures of the middleware components...
Many QoS constraints in network environments exists, beginning with hard real time networks on the field bus level, up to Differentiated Services or VLAN tagging for commodity computer networks. However, all these approaches are not applicable for cloud-based environments, where networks need to be configured dynamically and on-demand. In this paper, we present an approach for centralized and dynamic...
Many cloud solutions are a combination of complex components, which require a lot of time to install and to configure. This includes the setup or the adjustment of firewall policies and changes of many other system and infrastructure settings. Furthermore, additional software products are required, especially to setup a suitable and complex identity management. In this paper, we introduce a concept,...
Cloud computing has already been adopted in a broad range of application domains. However, domains like the distributed development of embedded systems are still unable to benefit from the advancements of cloud computing. Besides general security concerns, a common obstacle often is the incompatibility between such applications and the cloud. In particular, if applications need direct access to hardware...
Cloud Computing is becoming increasingly established and offers several opportunities to obtain IT services in an on-demand manner. Especially infrastructure services, like storage and scalable computing resources, are gaining relevance and provide alternatives to conventional sourcing models. Despite the Cloud paradigm of flexible and limitless scalability the lack of standardization presents a big...
We present a scalable approach to distributed data fusion based on the bandwidth- and latency-efficient hypercube topology. Provided the individual estimation errors are uncor-related, double-counting is avoided altogether by exploitation of the network topology, without the need for approximation with channel filters or pedigree logs. The fully allocated network is symmetric and exhibits no special...
