Managing cloud applications with variable resource requirements over time is an insipid task that could benefit from autonomic application management. the management platform will then need to know what the application owner considers a good deployment for the current execution context, which is normally captured by a utility function. However, it is often difficult to define such a function directly by first principles in a way that would perfectly capture the application owner's preferences. this paper proposes a methodology for defining the utility function only from the monitoring measurements taken to assess the state and context of the running application.

In this paper, we present an Adaptive Brokerage for the cloud (ABC) that can be used to simplify application deployment, monitoring and management processes in the cloud. the broker uses modern cloud infrastructure automation tools to test, deploy, monitor and optimise cloud resources. We used an e-commerce application to evaluate the entire functionality of the broker, we found out that different deployment options such as single-tier vs two-tier lead to interesting hardware and application performance insights. these insights are used to make effective infrastructure optimisation decisions.

Withthe emergence of the Internet of things and 5G technologies, the edge computing paradigm is playing increasingly important roles with better availability, latency-control and performance. However, existing autoscaling tools for edge computing applications do not utilize heterogeneous resources of edge systems efficiently, leaving scope for performance improvement. In this work, we propose a Proactive Pod Autoscaler (PPA) for edge computing applications on Kubernetes. the proposed PPA is able to forecast workloads in advance with multiple user-defined/customized metrics and to scale edge computing applications up and down correspondingly. the PPA is optimized and evaluated on an example CPU-intensive edge computing application further. It can be concluded that the proposed PPA outperforms the default pod autoscaler of Kubernetes on both efficiency of resource utilization and application performance. the article also highlights future possible improvements on the proposed PPA.

Critical applications deployed on cloud and in-house information technology infrastructures use software solutions known as highavailability clusters (HACs) to ensure higher availability. Our paper introduces a Bayesian prognostic (BP) framework that improves the ability ofHACs to (i) predict component failures that can be resolved by reinitialising the failed component and (ii) propagate and predict failures in high-level components when the component failure cannot be resolved through reinitialisation. Preliminary experiments presented in the paper demonstrate that this BP framework can reduce the downtime for an enterprise application subjected to a wide range of injected faults by between 5.5 and 7.9 times compared to the availability achieved by the open-source HAC ClusterLabs stack (Pacemaker/Corosync).

Selecting suitable cloud services and estimating future cloud costs for organizations with a large set of software services is a challenging task. To achieve this, one needs to understand all software applications' cloud service configuration requirements. Further, one needs to estimate how the applications' requirements change over time, e.g., due to scaling with a growing number of application users. then, one needs to compare for different cloud providers the costs over time of setups matching the requirements. this task, if done manually, is laborious, error prone, and has to be repeated when the organization's business or application requirements change. In my PhD project, I will research an integrated approach that assists users in, on the one hand, finding a cost-optimal selection of cloud services for given requirements and, on the other hand, estimating future costs. I want to achieve this withthe support of a software tool integrating existing research on the individual topics and, thereby, allowing to apply and study existing cloud service selection and cost estimation approaches.

Scalable application development is highly influenced by two major trends - serverless computing and continuum computing. these trends have had little intersection, as most application architectures, even when following a microservices or function-based approach, are built around rather monolithic Function-as-a-Service engines that do not span continuums. Functions are thus separated codewise but not infrastructure-wise, as they continue to run on the same single platform they have been deployed to. Moreover, developing and deploying distributed applications remains non-trivial and is a hurdle for enhancing the capabilities of mobile and sensing domains. To overcome this limitation, the concept of self-balancing architectures is introduced in which liquid functions traverse cloud and edge/fog platforms in a continuum as needed, represented by the abstract notion of pressure relief valves based on resource capacities, function execution durations and optimisation preferences. With CoRFu, a reference implementation of a continuum-wide distributed Function-as-a-Service engine is introduced and combined with a dynamic function offloading framework. the implementation is validated with a sensor data inference and regression application.
