Keynote Speech Title: Resource Allocation and Scheduling in Cloud and Fog Architectures – Challenges and Future Directions-
Summary: Cloud computing has been widely accepted in various sectors including academia and business. Resource allocation and application scheduling are important aspects of cloud computing. Due to the rapid growth of the Internet of Things (IoT) concept, fog computing has appeared as a computing paradigm used to solve constrains in cloud computing related to network congestion and transmission latency. The processing capacity of the fog resources is usually limited. Moreover, most of the IoT applications are delay-sensitive and the primary goal is meeting deadlines. Consequently, appropriate management of real-time applications is required for beneficial use of cloud and fog resources. In this keynote we will present novel techniques to address challenges in resource allocation and scheduling in cloud and fog computing infrastructures and we will provide future research directions in the cloud and fog computing research areas.
