abstract = {Today's infrastructure clouds provide resource elasticity (i.e. auto-scaling) mechanisms enabling self-adaptive resource provisioning to reflect variations in the load intensity over time. These mechanisms impact on the application performance, however, their effect in specific situations is hard to quantify and compare. To evaluate the quality of elasticity mechanisms provided by different platforms and configurations, respective metrics and benchmarks are required. Existing metrics for elasticity only consider the time required to provision and deprovision resources or the costs impact of adaptations. Existing benchmarks lack the capability to handle open workloads with realistic load intensity profiles and do not explicitly distinguish between the performance exhibited by the provisioned underlying resources, on the one hand, and the quality of the elasticity mechanisms themselves, on the other hand. In this paper, we propose reliable metrics for quantifying the timing aspects and accuracy of elasticity. Based on these metrics, we propose a novel approach for benchmarking the elasticity of Infrastructure-as-a-Service (IaaS) cloud platforms independent of the performance exhibited by the provisioned underlying resources. We show that the proposed metrics provide consistent ranking of elastic platforms on an ordinal scale. Finally, we present an extensive case study of real-world complexity demonstrating that the proposed approach is applicable in realistic scenarios and can cope with different levels of resource efficiency.},

abstract = {In software engineering, performance specifications of components support the successful evolution of complex software systems. Having trustworthy specifications is important to reliably detect unwanted effects of modifications on the performance using prediction techniques before they are experienced in live systems. This is especially important if there is no test system available and a system can't be taken down or replaced in its entirety. Existing approaches neglect stating the quality of specifications at all and hence the quality of the prediction is lowered if the assumption that all used specifications are suitable does not hold. In this paper, we propose a test-based approach to validate performance specifications against deployed component implementations. The validation is used to certify specifications which in turn allow assessing the suitability of specifications for predicting the performance of a software system. A small example shows that the certification approach is applicable and creates trustworthy performance specifications.},

abstract = {First person games are computer games, in which the user experiences the virtual game world from an avatar's view. This avatar is the user's alter ego in the game. In this paper, we present a telepresence interface for the first person game Quake III Arena, which gives the user the impression of presence in the game and thus leads to identification with his avatar. This is achieved by tracking the user's motion and using this motion data as control input for the avatar. As the user is wearing a head-mounted display and he perceives his actions affecting the virtual environment, he fully immerses into the target environment. Without further processing of the user's motion data, the virtual environment would be limited to the size of the user's real environment, which is not desirable. The use of Motion Compression, however, allows exploring an arbitrarily large virtual environment while the user is actually moving in an environment of limited size.},

abstract = {The broad introduction of multi-core processors made symmetric multiprocessing (SMP) environments mainstream. The additional cores can significantly increase software performance. However, their actual benefit depends on the operating system scheduler's capabilities, the system's workload, and the software's degree of concurrency. The load distribution on the available processors (or cores) strongly influences response times and throughput of software applications. Hence, understanding the operating system scheduler's influence on performance and scalability is essential for the accurate prediction of software performance (response time, throughput, and resource utilisation). Existing prediction approaches tend to approximate the influence of operating system schedulers by abstract policies such as processor sharing and its more sophisticated extensions. However, these abstractions often fail to accurately capture software performance in SMP environments. In this paper, we present a performance Model for general-purpose Operating System Schedulers (MOSS). It allows analyses of software performance taking the influences of schedulers in SMP environments into account. The model is defined in terms of timed Coloured Petri Nets and predicts the effect of different operating system schedulers (e.g., Windows 7, Vista, Server 2003, and Linux 2.6) on software performance. We validated the prediction accuracy of MOSS in a case study using a business information system. In our experiments, the deviation of predictions and measurements was below 10% in most cases and did not exceed 30%.},

abstract = {The shift of hardware architecture towards parallel execution led to a broad usage of multi-core processors in desktop systems and in server systems. The benefit of additional processor cores for software performance depends on the software's parallelism as well as the operating system scheduler's capabilities. Especially, the load on the available processors (or cores) strongly influences response times and throughput of software applications. Hence, a sophisticated understanding of the mutual influence of software behaviour and operating system schedulers is essential for accurate performance evaluations. Multi-core systems pose new challenges for performance analysis and developers of operating systems. For example, an optimal scheduling policy for multi-server systems, such as shortest remaining processing time (SRPT) for single-server systems, is not yet known in queueing theory. In this paper, we present a detailed experimental evaluation of general purpose operating system (GPOS) schedulers in symmetric multiprocessing (SMP) environments. In particular, we are interested in the influence of multiprocessor load balancing on software performance. Additionally, the evaluation includes effects of GPOS schedulers that can also occur in single-processor environments, such as I/Oboundedness of tasks and different prioritisation strategies. The results presented in this paper provide the basis for the future development of more accurate performance models of today's software systems.},

abstract = {{Although robotics has made progress with respect to adaptability and interaction in natural environments, it cannot match the capabilities of biological systems. A promising approach to solve this problem is to create biologically plausible robot controllers that use detailed neuronal networks. However, this approach yields a large gap between the neuronal network and its connection to the robot on the one side and the technical implementation on the other. Existing approaches neglect bridging this gap between disciplines and their focus on different abstractions layers but manually hand-craft the simulations. This makes the tight technical integration cumbersome and error-prone impairing round-trip validation and academic advancements. Our approach maps the problem to model-driven engineering techniques and defines a domain-specific language (DSL) for integrating biologically plausible Neuronal Networks in robot control algorithms. It provides different levels of abstraction and sets an interface standard for integration. Our approach is implemented in the Neuro-Robotics Platform (NRP) of the Human Brain Project (HBP). Its practical applicability is validated in a minimalist experiment inspired by the Braitenberg vehicles based on the simulation of a four-wheeled Husky robot controlled by a neuronal network.}},

However, auto-scaling features introduce new system quality attributes when considering their accuracy, timing, and boundaries. Therefore, distinguishing between different offerings has become a complex task, as it is not yet supported by reliable metrics and measurement approaches. In this paper, we discuss shortcomings of existing approaches for measuring and evaluating elastic behavior and propose a novel benchmark methodology specifically designed for evaluating the elasticity aspects of modern cloud platforms. The benchmark is based on open workloads with realistic load variation profiles that are calibrated to induce identical resource demand variations independent of the underlying hardware performance. Furthermore, we propose new metrics that capture the accuracy of resource allocations and de-allocations, as well as the timing aspects of an auto-scaling mechanism explicitly.}},

abstract = {Today, the architectures of software systems are not stable for their whole lifetime but often adapted driven by business needs. Preserving their quality characteristics beyond each of these changes requires deep knowledge of the requirements and the systems themselves. Proper documentation reduces the risk that knowledge is lost and hence is a base for the system's maintenance in the long-run. However, the influence of architectural documentation on the maintainability of software systems is neglected in current quality assessment methods. They are limited to documentation for anticipated change scenarios and do not provide a general assessment approach. In this paper, we propose a maturity model for architecture documentation. It is shaped relative to growing quality preservation maturity and independent of specific technologies or products. It supports the weighting of necessary effort against reducing long-term risks in the maintenance phase. This allows to take product maintainability requirements into account for selecting an appropriate documentation maturity level.},

abstract = {The implementation of an enterprise-wide Service Oriented Architecture (SOA) is a complex task. In most cases, evolutional approaches are used to handle this complexity. Maturity models are a possibility to plan and control such an evolution as they allow evaluating the current maturity and identifying current shortcomings. In order to support an SOA implementation, maturity models should also support in the selection of the most adequate maturity level and the deduction of a roadmap to this level. Existing SOA maturity models provide only weak assistance with the selection of an adequate maturity level. Most of them are developed by vendors of SOA products and often used to promote their products. In this paper, we introduce our independent SOA Maturity Model (iSOAMM), which is independent of the used technologies and products. In addition to the impacts on IT systems, it reflects the implications on organizational structures and governance. Furthermore, the iSOAMM lists the challenges, benefits and risks associated with each maturity level. This enables enterprises to select the most adequate maturity level for them, which is not necessarily the highest one.},

abstract = {Design-time quality analysis of software architectures evaluates the impact of design decisions in quality dimensions such as performance. Architectural design decisions decisively impact the energy efficiency (EE) of software systems. Low EE not only results in higher operational cost due to power consumption. It indirectly necessitates additional capacity in the power distribution infrastructure of the target deployment environment. Methodologies that analyze EE of software systems are yet to reach an abstraction suited for architecture-level reasoning. This paper outlines a model-based approach for evaluating the EE of software architectures. First, we present a model that describes the central power consumption characteristics of a software system. We couple the model with an existing model-based performance prediction approach to evaluate the consumption characteristics of a software architecture in varying usage contexts. Several experiments show the accuracy of our architecture-level consumption predictions. Energy consumption predictions reach an error of less than 5.5% for stable and 3.7% for varying workloads. Finally, we present a round-trip design scenario that illustrates how the explicit consideration of EE supports software architects in making informed trade-off decisions between performance and EE.}

title = {{Ensuring Model Continuity when Simulating Self-Adaptive Software Systems}},
year = {2016},
abstract = {Self-adaptivity in software systems aims to balance the use of costly resources, i.e. of servers and energy, under given constraints such as Quality of Service (QoS) requirements. Simulation does not require risky testing in running systems and has less assumptions and limitations than formal verification when evaluating the effect of self-adaptation mechanisms. Existing simulation frameworks for analyzing self-adaptive software systems require re-implementing algorithms to conform to the abstraction and interfaces of the simulation framework. We present an approach for coupling simulation-based analyses of self-adaptive software systems with self-adaptation mechanisms that eliminates the need to re-implement the mechanisms and ensures model continuity. The evaluation demonstrates the low complexity required when our approach is used to ensure model continuity between simulation and self-adaptation framework. It presents the results of two experiments we performed after coupling the SimuLizar simulation framework and the CACTOS runtime management framework for Cloud platforms. With this coupling, Cloud data center operators benefit from what-if-analyses of self-adaptation mechanisms and software engineers can optimize the QoS of systems on the drawing board without acquiring deep knowledge of simulation internals.}
