Prof. Omer Rana Title: Service Orchestration & Enactment Across Cloud & Edge Resources 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 and security constraints -- but with flexibility on where data processing is carried out. Biography: |
