   abstract = {Enterprise Topology Graphs (ETGs) represent a snapshot of the complete enterprise IT, including all its applications, processes, services, components, and their dependencies. In the past, ETGs have been applied in analysis, optimization, and adaptation of enterprise IT. But how to discover and maintain a complete, accurate, fresh, and fine-grained Enterprise Topology Graph? Existing approaches either do not provide enough technical details or do not cover the complete scope of Enterprise Topology Graphs. Although existing tools are able to discover valuable information, there is no means for seamless integration. This paper proposes a plugin-based approach and extensible framework for automated discovery and maintenance of Enterprise Topology Graphs. The approach is able to integrate various kinds of tools and techniques into a unified model. We implemented the proposed approach in a prototype and applied it to different scenarios. Due to the vital role of discovery plugins in our approach, we support plugin development with a systematic testing method and discuss the lessons we learned. The results presented in this paper enable new ways of enterprise IT optimization, analysis, and adaptation. Furthermore, they unlock the full potential of past research, which previously required manual modeling of ETGs.},

   abstract = {Modern Cloud applications employ a plethora of components and XaaS offerings that need to be configured during provisioning. Due to increased heterogeneity, complexity is growing and existing approaches reach their limits if multiple different provisioning and configuration technologies are involved. They are not able to integrate them in an automated, flexible, and customizable way. Especially combining proprietary management services with script-centric configuration management technologies is currently a major challenge. To enable automated provisioning of such applications, we introduce Generic Lifecycle Management Planlets that provide a means to combine custom provisioning logic with common provisioning tasks. We implemented planlets for provisioning and customization of components and XaaS offerings based on both SOAP and RESTful Web services as well as configuration management technologies such as Chef to show the feasibility of the approach. By using our approach, multiple technologies can be combined seamlessly.},

   abstract = {The automated provisioning of complex composite Cloud applications is a major issue and of vital importance in Cloud computing. It is key to enable Cloud properties such as pay-as-you-go pricing, on-demand self-service, and elasticity. The functional aspects of provisioning such as instantiating virtual machines or installing software components are covered by several technologies on different technical levels: some are targeted to a pretty high level such as Amazon’s Cloud Formation, some deal with deep technical issues based on scripts such as Chef or Puppet. However, the currently available solutions are tightly coupled to individual technologies without being able to consider non-functional security requirements in a non-proprietary and interoperable way. In this paper, we present a concept and framework extension enabling the integration of heterogeneous provisioning technologies under compliance with non-functional aspects defined by policies.},

New standards, such as TOSCA (OASIS), allow the modeling of interoperable Cloud services. It is now possible to build reusable and portable cloud services that can be (semi-) automatically deployed by different cloud-deployment-engines at various Cloud environments. However, there is still an acceptance problem among potential users, especially in the enterprise segment, that stems from security issues like data security. To improve security in automatic Cloud management engines, this paper proposes a framework for processing non-functional requirements of Cloud services.},

   abstract = {With the growing adoption of Cloud Computing, automated deployment and provisioning systems for Cloud applications are becoming more prevalent. They help to reduce the onboarding costs for new customers as well as the financial impact of managing Cloud Services by automating these previously manual tasks. With the widespread use of such systems, the adoption of a common standard for describing Cloud applications will provide a crucial advantage by enabling reusable and portable applications. TOSCA, a newly published standard by OASIS with broad industry participation provides this opportunity. Besides the technical requirements of running and managing applications in the cloud, non-functional requirements, like cost, security, and environmental issues, are of special importance when moving towards the automated provisioning and management of Cloud applications. In this paper we demonstrate how non-functional requirements are defined in TOSCA using policies. We propose a mechanism for automatic processing of these formal policy definitions in a TOSCA runtime environment that we have developed based on the proposed architecture of the TOSCA primer. In order to evaluate our approach, we present prototypical implementations of security policies for encrypting databases and for limiting the geographical location of the Cloud servers. We demonstrate how our runtime environment is ensuring these policies and show how they affect the deployment of the application.},

   abstract = {Product Lifecycle Management (PLM) comprises many different tasks across multiple domains, such as product development and production. Thus, multidisciplinary engineering teams have to collaborate to successfully design and produce products. Nowadays, engineers are supported with many software solutions, which are tailored to the work of each engineer. The problem is the missing or bad integration between these IT solutions, which leads to noncontinuous processes and an insufficient cooperation. The Service-oriented Architecture (SOA) supports the needed flexible integration of applications based on services and moreover an automation and integration of processes via workflows. In previous work, we proposed a service-oriented PLM architecture that provides these benefits and supports continuous processes. Thereby, services of different domains and phases of the product life cycle need to collaborate in a distributed fashion. In this paper, we systematically identify, define and rate representative models for the management of corresponding distributed service registries, which enable an efficient collaboration of services. Based on a prototypical implementation of the best-rated model in a layout redesign scenario, we assess our approach for its suitability in PLM. The selected service registry model provides transparent access to all services of different domains and shows the ease of integrating new applications into the product life cycle. It thereby enables an improved cooperation of engineers across various domains to define cross-domain processes.},

In this work, we identify three key-indicators to improve resource utilization during the load-balancing process: data skew, anticipated data access patterns and dynamic load peaks. For this reason, we introduce a comprehensive mathematical model to express the key-indicators as probability distribution functions. We fuse the different key-indicators into a single holistic distribution model. In the course of this, we devise a methodology from our holistic distribution model towards a distributed spatial cache offering improved load-balancing},

   abstract = {There is an increasing popularity of mobile devices-especially Android devices-particularly because of the huge amount of available third-party applications. Albeit, the number of diagnosed hacker attacks against mobile user increased in unison, as these devices became the prime target of the latest malware, thanks to inexperienced users and a negligent way of dealing with private data. To make matters worse, the Android permission system is much too coarse-grained and too hard to grasp for an average user. However, even if a user is able to comprehend the meaning and impact of a certain permission, in the end, s/he must grant all requested permission anyhow, if s/he wants to install the application. Therefore, we introduce PMP a privacy management platform for Android, which enables a user to grant an application fine-grained access rights to critical data. Furthermore, those rights can depend on some contextual constraints (e.g. Internet usage is restricted to certain locations) and the policy rules can be modified at run-time. Depending upon the granted rights an application provides a different scope of service. Moreover, the user is-due to a catchy GUI-always informed what impact the granting or respectively the revocation of a permission has on the application's service quality.},

   abstract = {The still rising popularity of modern mobile phones results in an increased demand for manifold applications for these devices. As Android OS supports the development and usage of third-party software greatly, there are more and more developers for this platform. However, many of those applications handle private data grossly negligent which immediately leads to serious privacy concerns. To make matters worse, the current Android permission rules are much too coarse and incomprehensible from the average user's perspective. But even if s/he understands the meaning of the permissions, s/he must either accept all of them or waive the application. Therefore we review concepts and approaches towards effective privacy management for mobile platforms. All this is discussed based on the prevailing key players in the mobile market, namely Apple, RIM, Microsoft and Google. As this work has been initiated by Google we mainly concentrated on Android-based concepts towards customizable privacy management approaches. As a result of our review and taking into account current initiatives and trends in the market, we come up with a novel approach, an implementation architecture and a prototype.},

Die Spezifikation der Patterns soll dabei m{\"o}glichst in der Sprache der mathematischen Simulationsmodelle erfolgen, mit denen Wissenschaftler vertraut sind. Eine Erweiterung des Workflowsystems bildet die Patterns automatisch auf ausf{\"u}hrbare Workflowfragmente ab, welche die Datenbereitstellung umsetzen.

   abstract = {The ability to continuously adapt its business processes is a crucial ability for any company in order to survive in todays dynamic world. In order to accomplish this task, a company needs to profoundly analyze all its business data. This generates the need for data integration and analysis techniques that allow for a comprehensive analysis. A particular challenge when conducting this analysis is the integration of process data generated by workflow engines and operational data that is produced by business applications and stored in data warehouses. Typically, these two types of data are not matched as their acquisition and analysis follows different principles, i.e., a process-oriented view versus a view focusing on business objects. To address this challenge, we introduce a framework that allows to improve business processes considering an integrated view on process data and operational data.We present and evaluate various architectural options for the data warehouse that provides this integrated view based on a specialized federation layer. This integrated view is also reflected in a set of operators that we introduce.We show how these operators ease the definition of analysis queries and how they allow to extract hidden optimization patterns by using data mining techniques.},

Current analyses typically run either on business process execution data or on operational business data. Correlations among the separate data sets have to be found manually under big effort. However, to achieve a more informative analysis and to fully optimize a company's business, an efficient consolidation of all major data sources is indispensable. Recent matching algorithms are insufficient for this task since they are restricted either to schema or to process matching. We present a new matching framework to (semi-)automatically combine process data models and operational data models for performing such a profound business analysis. We describe the algorithms and basic matching rules underlying this approach as well as an experimental study that shows the achieved high recall and precision.},

   abstract = {Manufacturing companies are operating today in a turbulent market. Permanently changing preconditions forces the companies to continuously adapt their business and production processes to get the optimal productivity. Therefore, a vast number of IT systems are introduced to support tasks along the product life cycle. These systems are typically isolated and their communication, cooperation and in special cases also integration results in more and more overhead and gets quickly unmanageable. Further problems arise, when building continuous processes within the Product Lifecycle Management (PLM). The service-based PLM architecture faces these challenges and presents a homogeneous integration approach based on Enterprise Service Bus (ESB) technology. The characteristics and findings of our approach are presented and the inclusion of security features is discussed. A proof-of-concept for the production planning and the corresponding Production Planning Service Bus are presented. Finally, the advantages of the service-based approach compared to traditional integration solutions are pointed out.},
