The New Clouds on the Block

ABSTRACT

The growth of capable devices at the edge of the Internet is providing a unique, but mostly overlooked, opportunity to overcome cloud computing limitations without the cost of deploying local clouds (cloudlets). What trends support this assertion? While the gap remains between truly mobile devices (handhelds, wearable) and high capacity servers, mobile devices have grown increasingly powerful, especially when laptops are included. Devices at the edge are mostly idle or underutilized and can be clustered together to provide significant compute resources. Efficiently utilizing the available devices at the edge as compute resources to assist neighboring devices have a natural scaling property not enjoyed by a cloudlet, which must be provisioned ahead of time. Leveraging devices at the edge requires answers to the following: (1) How to provide a stable interface with these clouds, overcome their dynamic nature, and provide their users with performance guarantees? (2) How to efficiently discover and utilize the available resources in devices without affecting their main user experiences or disrupting their main functionalities? (3) How to provide users with proper incentives to share their resources? (4) How do mobile device clouds fit in the cloud computing ecosystem? In this talk I will discuss multiple approaches to realizing mobile edge clouds including those constructed from emerging IoT devices.

Bio

Ellen W. Zegura received the BS in Computer Science, the BS in Electrical Engineering, the MS in Computer Science and the D.Sc. in Computer Science, all from Washington University in St. Louis, Missouri. Since 1993 she has been on the faculty of the College of Computing at Georgia Tech where she conducts research and teaches in computer networking and computing for development. In 2008, she helped create the Computing for Good initiative in the College of Computing, a project-based teaching and research activity that focuses on the use of computing to solve pressing societal problems. She is a Fellow of the IEEE, a Fellow of the ACM, and an elected member of the Computing Research Association Board (CRA). Since fall 2004 she has been on the Executive Board of the CRA. She served on the NSF CISE Advisory Committee from 2005-2009.
