Colloquium: Vertical workflows: Service Orchestration Across Cloud & Edge Resources, Prof. Omer F. Rana (Cardiff University, UK), Wednesday, November 6, 2019, 10:00-11:00 EET.
The Department of Computer Science at the University of Cyprus cordially invites you to the Colloquium entitled:
Vertical workflows: Service Orchestration Across Cloud & Edge Resources
 |
Speaker: Prof. Omer F. Rana |
Abstract:
Many Internet of Things (IoT) applications today involve data capture
from sensors that are close to the phenomenon being measured, with such
data subsequently being transmitted to Cloud data centers for analysis
and storage. Currently devices used for data capture often differ from
those that are used to subsequently carry out analysis on such data.
Increasing availability of storage and processing devices closer to the
data capture device, perhaps over a one-hop network connection or even
directly connected to the IoT device itself, requires more efficient
allocation of processing across such edge devices and data centers.
Scalability in this context needs to consider both cloud resources and
initial processing on edge resources closer to the user. We refer to
these as "vertical workflows" – i.e. workflows (a combined set of
services) which are enacted across resources that can vary in: (i) type
and behaviour; (ii) processing and storage capacity; (iii) latency and
security profiles. Understanding how a workflow can be enacted across
these resource types is outlined, motivated through multiple application
scenarios. The overall objective considered is the completion of the
workflow within some deadline constraint, but with flexibility on where
data processing is carried out.
Short Bio:
Omer F. Rana is Professor of Performance Engineering at Cardiff
University, with research interests in high performance distributed
computing, data analysis/mining and multi-agent systems. He was formerly
the deputy director of the Welsh eScience Centre and had the opportunity
to interact with a number of computational scientists across Cardiff
University and the UK. He is a fellow of Cardiff University's
multi-disciplinary "Data Innovation" Research Institute. Rana has
contributed to specification and standardisation activities via the Open
Grid Forum and worked as a software developer with London-based Marshall
Bio-Technology Limited prior to joining Cardiff University, where he
developed specialist software to support biotech instrumentation. He
also contributed to public understanding of science, via the Wellcome
Trust funded "Science Line", in collaboration with BBC and Channel 4.
Rana holds a PhD in "Neural Computing and Parallel Architectures" from
Imperial College (London Univ.), an MSc in Microelectronics (Univ. of
Southampton) and a BEng in Information Systems Eng. from Imperial
College (London Univ.). He serves on the editorial boards (as Associate
Editor) of IEEE Transactions on Parallel and Distributed Systems,
(formerly) IEEE Transactions on Cloud Computing, IEEE Cloud Computing
magazine and ACM Transactions on Internet Technology. He is a
founding-member and associate editor of ACM Transactions on Autonomous &
Adaptive Systems.
