PhD position on Performance Observability in Cloud-Edge Continuum (1.0 FTE)

Published Deadline Location
15 Jun today Utrecht
Are you ready for an exciting opportunity to contribute to research and design of an observable and reliable computing continuum?

Job description

Nowadays large-scale software applications (e.g., streaming and gaming services, enterprise applications) are running on distributed systems that are evolving towards an interconnected continuum consisting of high-end cloud servers to mid-range fog gateways and low-end heterogeneous edge devices. On the one hand, such a scalable continuum continues to improve the agility, responsiveness and effectiveness of highly distributed applications. On the other hand, this paradigmatic shift has also introduced significant complexities to the resource and service management layers. These include challenges related to performance optimisation and maintenance in large-scale distributed systems. Of particular interest are the so-called performance variability and degradation issues, which often impact the reliability of the infrastructure and services. Simply put, variability and degradation refer to fluctuating application performance indicators due to anomalous performance events (e.g., resource interference, unpredictable workload, or correlated faults) in the underlying infrastructure, further inducing undesirable performance behaviour and service outages. Such issues will only aggravate due to cloud-edge systems' increasing scale and heterogeneity. This calls for the need to research cloud-edge management paradigms with more visibility and control over system parameters, infrastructure dependencies, and application constraints impacting the performance.

In this PhD position you focus on contributing to the theory and design of holistic performance observability (i.e. measuring the internal states of a system by examining its output) solutions in cloud-edge based systems. You will focus on diagnosis, prognosis, causal attribution and analysis of anomalous performance events, evaluating their impacts/trade-offs, localising their actual root cause (s), and suggesting or actuating mitigations. You contribute to our long-term objective to define open standards and develop observability benchmarks that enhances experiment reproducibility in cloud-edge systems.

You will:

  • analyse the literature to understand the state-of-the-art in edge-cloud performance observability, diagnosis, prognosis and their limiting factors in resource management;
  • design a generalised observability theory and understand the ramifications of design choices, restrictions, and trade-offs in large scale cloud-edge systems;
  • research and implement diagnosis and prognosis algorithms to infer the observable and non-observable anomalous events when localising their causality;
  • develop a performance management prototype that benchmarks degradation and variability scenarios in a controlled environment and validates them based on the developed observability theory and heuristics to provide early detection and mitigation of performance issues.

The position includes research as well as teaching. Approximately 30% of your time will be spent performing varying teaching (support) activities. We offer the opportunity to take significant steps towards acquiring a basic teaching qualification (BKO), which qualifies you as a teacher in the Dutch higher education system.

Employer

The PhD position is embedded in the division Intelligent Software Systems within the research group of Organisation and Information. This group is part of the Department of Information and Computing Sciences.The department is nationally and internationally renowned for its fundamental and applied research in computer science and information science. In our constantly changing (digital) society, the Department of Information and Computing Sciences is constantly looking for new, realistic ways to push the boundaries of both science and social application. We contribute to innovative information technologies through the development and application of new concepts, theories, algorithms, and software methods. Relevant areas of interdisciplinary research include Game Research, Foundations of Complex Systems, Applied Data Science, and Artificial Intelligence.

At the Faculty of Science, there are 6 departments to make a fundamental connection with: Biology, Chemistry, Information and Computing Sciences, Mathematics, Pharmaceutical Sciences, and Physics. Each of these is made up of distinct institutes that work together to focus on answering some of humanity’s most pressing problems. More fundamental still are the individual research groups – the building blocks of our ambitious scientific projects. Find out more about us.

Utrecht University is a friendly and ambitious university at the heart of an ancient city. We love to welcome new scientists to our city – a thriving cultural hub that is consistently rated as one of the world’s happiest cities. We are renowned for our innovative interdisciplinary research and our emphasis on inspirational research and excellent education. We are equally well-known for our informal atmosphere and the can-do mentality of our people.
