keynote speech : “Scheduling Complex Real-Time Applications in the Cloud and in the Fog”.

Abstract:

       Cloud computing has become a popular computing paradigm for the deployment of complex computationally intensive applications. However, many important issues must be addressed in order to exploit cloud’s full potential. Effective resource allocation, job scheduling, cost, quality of service, availability and reliability are some of the issues which require attention for good performance and users’ satisfaction.
Generally, complex job scheduling in large scale distributed systems is a challenging problem. Particularly important is the effective scheduling of complex real-time applications, considering timeliness along with energy conservation. Therefore, energy efficient scheduling techniques are needed ensuring that the deadlines of complex applications will be met.
Due to the increasing number of Internet of Things applications, fog computing appeared recently as a new paradigm beyond cloud computing. Most of the applications in the IoT domain need new solutions for timeliness and quality of service. Real-time applications should be appropriately assigned to resources in both the fog and cloud layers, taking into account the communication and computational characteristics of each application.
In this talk we will present research covering various concepts on scheduling complex real-time applications in cloud and fog systems and we will provide future research directions in the cloud and fog computing area.
