VM-based Cloudlets in Mobile Computing
Abstract
Resource poverty is a
fundamental constraint that severely limits the class of applications that can
be run on mobile devices. In this talk, I will present a vision of mobile
computing that breaks free of this fundamental constraint. In this vision,
mobile users seamlessly utilize nearby computers to obtain the resource
benefits of cloud computing without incurring WAN delays and jitter. Rather
than relying on a distant cloud, a mobile user instantiates a cloudlet on
nearby infrastructure and uses it via a wireless LAN. Crisp interactive
response for immersive applications that augment human cognition is then much
easier to achieve because of the proximity of the cloudlet. Preliminary results
confirm that a critical aspect of this vision, namely rapid customization of
cloudlet infrastructure, is achievable through a technique called dynamic VM
synthesis.
Prof. Mahadev Satyanarayanan (Satya)
Satya is an experimental computer scientist
who has pioneered research in mobile and pervasive computing. One outcome is
the open-source Coda File System, which supports
distributed file access in low-bandwidth and intermittent wireless networks
through disconnected and bandwidth-adaptive operation. The Coda concepts of hoarding, reintegration and application-specific
conflict resolution
can be found in the hotsync capability of PDAs today. Key ideas from Coda have
been incorporated by Microsoft into the IntelliMirror component of Windows
2000 and the Cached Exchange Mode of Outlook 2003.
Another outcome of Satya's work is Odyssey, a set of open-source
operating system extensions that enable mobile applications to adapt to
variation in critical resources such as network bandwidth and energy. Coda and
Odyssey are building blocks in Project Aura, a research initiative at Carnegie
Mellon to explore distraction-free ubiquitous computing. His most recent
work in this space is Internet
Suspend/Resume,
a hands-free approach to mobile computing that exploits virtual machine
technology to liberate personal computing state from hardware. Satya is a
co-inventor of many supporting technologies relevant to mobile and pervasive
computing, such as data staging, lookaside caching, translucent caching and application-aware
adaptation.
He is also a co-inventor of the Diamond approach to
interactive, non-indexed search of complex and loosely-organized data such as
digital photographs and medical images. Early in his career, Satya was a
principal architect and implementor of the Andrew File System (AFS) which pioneered the
use of scalable file caching, ACL-based security, and volume-based system
administration for enterprise-scale information sharing. AFS was commercialized by IBM, is in widespread
use today as OpenAFS, and has heavily
influenced the NFS v4 network file system
protocol standard that was published in April 2003.
Satya is the Carnegie
Group Professor of Computer Science at Carnegie Mellon
University.
From May 2001 to May 2004 he served as the founding director of Intel Research Pittsburgh, one of four
university-affiliated research labs established worldwide by Intel to create
disruptive information technologies through its Open Collaborative Research
model. Satya 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 and the IEEE, and was the founding
Editor-in-Chief of IEEE Pervasive Computing.
