The Limits of Cloud Computing and the Emergence of Edge Computing

Mahadev Satyanarayanan
School of Computer Science
Carnegie Mellon University

Abstract

In 2024, the cloud computing market was estimated to be over $600 billion in value. The cloud lies at the heart of virtually all of the recent advances in machine learning (ML) and ML-based artificial intelligence (AI). Large Language Models (LLMs) such as ChatGPT have captured the popular imagination. Cloud computing was crucial to the work that won the Nobel Prize in Physics, and the Nobel Prize in Chemistry in 2024. For the foreseeable future, cloud computing will continue to be a dominant paradigm.
What accounts for this stunning success of cloud computing? What could possibly threaten its dominance? In this talk, we will explore how the constraints of latency, bandwidth scalability, privacy, data sovereignty, and disconnection-tolerance pose fundamental limits to what cloud computing can deliver in real-world settings, especially adversarial settings. Cloudlet-based edge computing aims to “bring the cloud closer” to relieve these pain points. The successful real-time AI systems of the future will seamlessly fuse the strengths of cloud computing and edge computing. What are some of the transformative cyber-human and cyber-physical systems that will emerge? What challenges will edge computing face, both in adversarial and non-adversarial settings? What is the role of application-specific hardware accelerators in real-time AI? We will examine these and related questions in this talk.

Speaker Biography

Satya’s multi-decade research career has focused on the challenges of performance, scalability, availability and trust in information systems that reach from the cloud to the mobile edge of the Internet. In the course of this work, he has pioneered many advances in distributed systems, mobile computing, pervasive computing, and the Internet of Things (IoT). Most recently, he has been viewed as “The Father of Edge Computing” for his seminal 2009 paper, and his pioneering contributions to the
foundations of edge computing. Satya is the Jaime Carbonell University Professor of Computer Science at Carnegie Mellon University. He received the PhD in Computer Science from Carnegie Mellon, after Bachelor’s and Master’s degrees from the Indian Institute of Technology, Madras. He is a Fellow of the ACM, IEEE, and EAI, and a member of the National Academy of Engineering.

Balancing the Trilemma: A Unified Approach for Cost-Effective, Energy-Efficient and Performant LLM Serving

Tamar Eilam
IBM T. J. Watson Research Center

Abstract

Large Language Models have transformed cloud computing, but their deployment presents a challenging trilemma between operational costs, energy consumption, and performance requirements. This keynote presents a novel open architecture that harmonizes multiple efficiency techniques to address these competing concerns. We examine critical optimization strategies including quantization, batching strategies, KV-caching, auto-scaling, model parallelisms, and specialized hardware accelerators—analyzing their individual strengths and compounding benefits when integrated as a cohesive system.

PCU – The New Health Service Architecture

Ramesh Jain 
Institute for Future Health
Department of Computer Science
University of California, Irvine

Abstract

Healthcare remains trapped in a reactive paradigm where sophisticated monitoring occurs only during crisis. The Personal Care Unit (PCU) concept represents a radical reimagining of health services, transforming care from episodic interventions to continuous, personalized support embedded in daily life. This presentation introduces PCU as an integrated service architecture built on three pillars: comprehensive lifestyle optimization (with food computing as its cornerstone), Personicles (personal chronicles creating narrative-driven health timelines), and multimodal health agents powered by generative AI. These agents serve as Personal Health Navigators that interpret complex patterns and deliver contextually appropriate guidance through natural interactions. Unlike traditional service models focused on illness, the PCU paradigm centers on the person as an active participant in their health journey, with AI augmenting rather than replacing human judgment. The technical foundations supporting this vision—from multimodal sensing networks to privacy-preserving edge computing—represent frontier challenges for service engineering. This presentation will examine implementation approaches, architectural requirements, and critical research directions that the community must address to realize this transformative vision—one that promises not just incremental improvements in healthcare delivery but a fundamental redefinition of how health services integrate with daily living.

Services with UNEXT – What You Need, is What You Get

Azimeh Sefidcon
Nokia Bell Labs

Abstract

The service-based business and architectures have extended the opportunities to diverse set of actors across ecosystem. Challenges of service composition however needs to be resolved together with their execution environment and dynamic value chains of involved actors. Approaching this context correctly creates a unified networking experience for users, application developers, verticals and infrastructure operators alike. UNEXT addresses these challenges by introducing run time service composition in multi actor environments while ensuring sustainability, simplicity and security concerns. In this talk the motivation for this novel approach and different system elements will be presented.
