For several years now there has been significant research in cloud computing. However, there still exist many open challenges due to the heterogeneity of cloud resources and the characteristics of the applications executed on such infrastructures. Cloud computing platforms offer an efficient means to run real-time applications. One of the most important aspects in cloud computing is the effective scheduling of real-time complex parallel jobs, allowing for guarantees that the deadlines will be met. Furthermore, the energy efficiency of cloud systems is very important. However, to reduce the energy consumption while meeting deadlines, adaptive scheduling techniques are required. In this talk we will present recent research covering a variety of concepts on real-time complex jobs scheduling in the cloud, and we will provide future research directions.
