Abstract: Edge computing is new paradigm in which the resources of a small data center are placed at the edge of the Internet, in close proximity to mobile devices, sensors, and end users. Terms such as "cloudlets," "micro data centers," "fog," and "mobile edge cloud" have been used in the literature to refer to edge-located data centers. Located just one wireless hop away from associated mobile devices, they offer ideal placement for low-latency offload infrastructure to support emerging applications. They are optimal sites for aggregating, analyzing and distilling bandwidth-hungry sensor data from devices such as video cameras. In the Internet of Things, they offer a natural vantage point for organizational access control, privacy, administrative autonomy and responsive analytics. In vehicular systems, they mark the junction between the well-connected inner world of a moving vehicle and its tenuous reach into the cloud. For cloud computing, they enable fallback cloud services in hostile environments. Starting from the widely-used OpenStack platform for cloud computing, we describe our extensions for cloudlet discovery, just-in-time provisioning, and VM handoff. These mechanisms lay the foundation for the future emergence of a rich and diverse multi-vendor ecosystem of applications and instrastructure for edge computing.
Bio: 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. Most recently, his seminal 2009 publication “The Case for VM-based Cloudlets in Mobile Computing” has inspired many technical efforts worldwide at the intersection of mobile computing and cloud computing, and has led to the emergence of Edge Computing (also known as "Fog Computing").
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, has heavily influenced the NFS v4 network file system protocol standard, and was the inspiration for DropBox. Building on the AFS work, Satya was a principal architect of the Coda File System which introduced the concepts of disconnected operation and bandwidth-adaptive weakly-connected operation in distributed file systems. The Coda concepts of hoarding, reintegration and application-specific conflict resolution can be found in the hotsync capability of mobile devices today. Key ideas from Coda were incorporated by Microsoft into the IntelliMirror component of Windows 2000 and the Cached Exchange Mode of Outlook 2003. The Odyssey project explored the partitioning of responsibility between the operating system and applications in adapting to wide variability in critical resources such as wireless network bandwidth and energy in mobile computing. Through these and other projects such as Aura and Chroma, Satya was a co-inventor of many supporting technologies for mobile computing such as such as cyber foraging (also known as "cloud offload"), data staging, lookaside caching, translucent caching and application-aware adaptation. In the Internet Suspend/Resume system, his team has explored the role of virtual machine (VM) technology in seamless mobility of legacy software. In the Diamond project. his team has explored interactive deep search of unindexed complex data such as digital photographs and medical images in domains such as pathology, dermatology and anomaly detection in drug discovery. The creation of OpenSlide, a widely-used vendor-neutral software library for digital pathology was a by-product of the Diamond work. His most recent work in distributed systems has focused on the Olive project, which is exploring the streaming and prefetching of virtual machines over the Internet as the foundational mechamism for archived executable content. At the convergence of cloud computing and mobile computing, his most recent work in the Elijah project is exploring the role of cloudlets, which are decentralized cloud computing elements located close to edge of the Internet. Cloudlets enable mobile devices to offload resource-intensive computation at low latency and high bandwidth, thus pointing the way to futuristic applications such as wearable cognitive assistance on devices such as Google Glass and Microsoft Hololens.
Satya is the Carnegie Group 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 and the IEEE. He was the founding Program Chair of the HotMobile series of workshops, the founding Editor-in-Chief of IEEE Pervasive Computing, the founding Area Editor for the Synthesis Series on Mobile and Pervasive Computing, and is the founding program chair of the First IEEE Symposium on Edge Computing that will be held in October 2016. He was the founding director of Intel Research Pittsburgh, and was an Advisor to Maginatics , which has created a cloud-based realization of the AFS vision and was acquired by EMC in 2014.
Abstract: Managing risk in changing environments is a classic challenge for decision makers in public, private, and nonprofit organizations. The challenge increases as decision makers discover the interconnectedness of the systems they manage and the unexpected consequences of decisions made to reduce risk in one set of circumstances that actually increase risk for different groups of the population under different conditions. Perceived in practice, risk is a set of dynamic, interacting conditions involving multiple actors, changing technologies, conflicting assumptions, different scales of operation, and the need for timely, informed, collective action to mobilize a coherent response. Managing risk is an on-going effort in Nepal, which experienced a major earthquake on April 25, 2015, with recurring aftershocks and changing political, economic, and technological conditions. Turning risk into opportunity for informed development is a fundamental task, not only for Nepal, but globally, for the 21st century.

Abstract: Community analysis is an important aspect of internet and social networks. Recently, the formulation and analysis of communities have been hot topics in data mining and social networks. The growing need for understanding user relationships and behaviors in internet and social networks requires the tracking of user communities over time. Temporal information in dynamic social networks can be used to reveal many important phenomena such as bursts of activities in social networks. In this talk, based on our newest findings, I will present computational approaches to identify the roles of communities and to track the patterns of communities in dynamic internet and social networks. Significant communities which are correlated to observable various semantics can be identified. I will discuss new methods to formulate, measure, and track the community consistency under dynamic settings. These methods will be helpful for the analysis of internet and social networks and also for understanding user behaviors over time. The measurement and tracking of community consistency are challenging since we need to explore the causes of evolving community structures. I will demonstrate several case studies to show the effectiveness in real-world applications.

Abstract: This talk, which is based on our newest findings and experiences from research and industrial projects, addresses one of the most relevant challenges for a decade to come: How to integrate the Internet of Things with software, people, and processes, considering modern Cloud Computing and Elasticity principles. Elasticity is seen as one of the main characteristics of Cloud Computing today. Is elasticity simply scalability on steroids? This talk addresses the main principles of elasticity, presents a fresh look at this problem, and examines how to integrate people, software services, and things into one composite system, which can be modeled, programmed, and deployed on a large scale in an elastic way. This novel paradigm has major consequences on how we view, build, design, and deploy ultra-large scale distributed systems.

Abstract: Recognition that anthropogenic carbon emissions are driving climate change has led to adoption of ambitious new “renewable portfolio standards” (50% in California and New York for 2030, and DOE’s Wind Power vision for a 35% national RPS for 2050). Such radical changes posit future power grids with high generation variability, creating many terawatt-hours (TWh) of “stranded power” – energy that is generated, but has no economic value.
We propose a new model for large-scale computing, Zero-carbon Cloud (ZCCloud), that presents computing as a “dispatchable load”, exploiting stranded power to eliminate carbon emissions, and to enhance grid stability and efficiency. First, we characterize stranded power as a plentiful (10’s of TWh), growing, and usable resource (duty factors 60-80%). Second, study using production workloads shows that ZCCloud’s can create intermittent computing resources from stranded power that are be highly productive, and in a range of future scenarios, enable both higher “peak capability” supercomputers and economically competitive cloud systems. Finally, using advanced power grid simulation techniques, we compare the impact of traditional cloud data centers and ZCCloud’s new “dispatchable” loads, finding significant improvements in power cost, achieved RPS, and reduced stranded power. Our results also suggest that conventional approaches that add wind or solar renewables to cloud data centers, may be net detrimental to both power grid performance and carbon footprint. They also raise interesting challenges for future wide-area networks and clouds where entire data centers enter and exit on an hourly basis.
