Overview
Overview
The HotCloudPerf workshop proposes a meeting venue for academics and practitioners, from experts to trainees, in the field of cloud computing performance. The new understanding of cloud computing covers the full computational continuum from data centers to edge resources to IoT sensors and devices. The workshop aims to engage this community and to lead to the development of new methodological aspects for gaining a deeper understanding not only of cloud performance, but also of cloud operation and behavior, through diverse quantitative evaluation tools, including benchmarks, metrics, and workload generators. The workshop focuses on novel cloud properties such as elasticity, performance isolation, dependability, and other non-functional system properties, in addition to classical performance-related metrics such as response time, throughput, scalability, and efficiency.

Cristian Klein: Using Cloud Native Technologies to Understand the Performance of Cloud Native Technologies
Cristian Klein: Using Cloud Native Technologies to Understand the Performance of Cloud Native Technologies
Umeå University, Sweden
Description: The ambition of this talk is to help seed discussions around how cloud native technologies can help research on performance engineering, but also what are the interesting performance engineering challenges to solve with cloud native technologies.
Cloud native technologies are building blocks for creating a modern environment for hosting containerized applications. Amongst others, great focus is placed on observability, which allows engineers to collect and analyze massive amounts of performance data in near real-time. Take as an example service meshes, which are a layer 7 network platform for containerized applications. Service meshes not only allow traffic engineering, but also add observability on top of a microservice application. Amongst other, this allows understanding traffic patterns between microservices, including upstream-downstream relationships, request rate, etc. without writing a single line of code.
In this talk, I will discuss how cloud native technologies may help researchers in performance engineering. The benefits are three-fold. They allow researchers – e.g., PhD students – to be more productive, by getting the mechanism of collecting performance data out of the way. They improve collaboration because the effects of changing a parameter can be visualized in near real time. Finally, experiments are based on proven technologies with skills more widely available, which helps reproducibility.
I will illustrate these benefits through our research on adaptive service meshes. Indeed, service meshes have many parameters which impact application performance. Discussions with practitioners revealed a gap in understanding on how to effectively choose these parameters. We therefore proposed an adaptive controller that configures a service mesh so as to maintain a target tail response time.
Bio: Cristian Klein is a cloud architect at Elastisys and an adjunct lecturer at Umeå University. His role involves looking at data protection regulations and security best practices to make architectural decisions. He gathered over 18 years of experience in operating IT systems. He acted variously as researcher, teacher, consultant and practitioner. His research interests include cloud native technologies, information security and service meshes.
Tania Lorido Botran: Scaling the Metaverse - an AI perspective
Tania Lorido Botran: Scaling the Metaverse - an AI perspective
Roblox, USA
Description: When one hears the word Metaverse, it is automatically associated with millions of users, immersive experiences and its potential to change our lives. But, what enables the Metaverse to function at such a scale? This talk will present the different challenges associated with handling 55 million daily users within the Roblox Metaverse. From addressing user Quality of Experience, to distributed architecture, programming model and scheduling, we will cover the entire stack underneath. In particular, I will put special attention into the AI-Metaverse relationship. On one hand, a large proportion of workloads are based on one or multiple ML/DL models and I will present the challenges of scaling them. On the other hand, I will explore infrastructure and service model challenges that can be addressed with AI, e.g. multi-resource and multi-datacenter scheduling with Reinforcement learning.
Bio: Dr. Tania Lorido-Botran is a Research Scientist at Roblox. Prior to that, she worked at Microsoft and the Pacific Northwest National Laboratory. During her PhD, she had the opportunity to spend one year at Rice University and also did two internships at VMware and HP Labs. Dr. Lorido Botran received her PhD from the University of Deusto in Spain with a Cum Laude distinction, and her master’s degree in Distributed systems from University of the Basque Country with a highest marks distinction. Her current research interests span across ML for systems, data center sustainability and fault-tolerance.
