Mahadev Satyanarayanan, professor of computer science from Carnegie Mellon University, will give the QoSA keynote. In line with the theme "The System View" of the federated conference on the Quality of Software Architectures (QoSA 2013), Satya will discuss the impact of mobility on system architecture.


Cloudlets: at the Leading Edge of Cloud-Mobile Convergence

Keynote abstract by Mahadev Satyanarayanan.

Since the dawn of mobile computing two decades ago, the unique constraints of mobility have shaped the software architectures of systems. We now stand at the threshold of the next major transformation in computing: one in which the rich sensing and interaction capabilities of mobile devices are seamlessly fused with compute-intensive and data-intensive processing in the cloud. This heralds a new genre of software that augments human perception and cognition in a mobile context. A major obstacle to realizing this vision is the large and variable end-to-end WAN latency between mobile device and cloud, and the possibility of WAN disruptions. Cloudlets have emerged as an architectural solution to this problem. A cloudlet represents the middle tier of a 3-tier hierarchy: mobile device --- cloudlet --- cloud, and can be viewed as a "data center in a box" whose goal is to "bring the cloud closer". A cloudlet-based hardware/software ecosystem inspires futuristic visions such as cognitive assistance for attention-challenged mobile users, scalable crowd-sourcing of first-person video, and ubiquitous mobile access to one's legacy world. Realizing these visions will require many technical challenges to be overcome. It will also require us to rethink a wide range of issues in areas such as privacy, software licensing, and business models.

Mahadev Satyanarayanan is a professor of computer science from Carnegie Mellon University. He is an experimental computer scientist who has pioneered research in distributed systems, mobile computing and pervasive computing. Early in his career, Satya was a principal architect of the Andrew File System (AFS) and later the Coda File System, which were commercialized by IBM and adopted by Microsoft for Windows, respectively. Later, Satya was a co-inventor of many supporting technologies for mobile computing such as cyber foraging, data staging, lookaside caching, translucent caching and application-aware adaptation. His most recent work in mobile computing has focused on the role of virtual machine (VM) technology, in the context of the Internet Suspend/Resume system and the use of cloudlets for cyber foraging.

Satya is the Carnegie Group Professor of Computer Science at Carnegie Mellon University. He is a Fellow of the ACM and the IEEE. He was the founding Program Chair of the HotMobile series of workshops, the founding Editor-in-Chief of IEEE Pervasive Computing, and the founding director of Intel Research Pittsburgh.
