Scheduling Complex Jobs in the Cloud – Challenges and Future Directions


Speaker: Helen Karatza

Professor Emeritus, Department of Informatics, Aristotle University of Thessaloniki, Greece




Cloud computing offers virtually unlimited computing resources on a pay-per-use approach to end users for running complex computationally intensive jobs without the problem of acquiring and maintaining expensive computers.

 However, there are important issues that must be addressed in order to exploit cloud computing full potential. This is mainly due to the scale of the cloud and the increasing number of cloud users and applications deployed in it. Critical issues are effective resource allocation, job scheduling, cost, quality of service, energy conservation. The scheduling algorithms must provide good performance to leasing cost ratio.

 Generally, job scheduling in large scale distributed computing systems is a challenging problem. Particularly important in cloud computing is the effective scheduling of complex real-time applications, taking into account not only the job response time but also the cost of the energy consumption for the cloud providers. Therefore, energy efficient scheduling strategies are required allowing for guarantees that the deadlines of complex jobs will be met.

 In this talk we will present recent research covering various concepts on complex jobs scheduling in the cloud and we will provide research directions and challenges in the cloud computing area.
