Abstract: 

The dynamic and heterogeneous nature of the underlying cloud platform and infrastructure introduces several deficiencies for agile development, automated deployment, and efficient and effective execution of cloud applications. In this talk, I will present our advances in several aspects of distributed cloud application life-cycles. The main focus will be given on development, modeling, and running serverless workflow applications or function choreographies (FCs) in federated FaaS. Firstly, novel programming models for building hybrid FCs with FaaSification and portable and scalable FCs at a high-level of abstraction will be described. Secondly, the novel FC simulation model for Federated FaaS will be detailed. Finally, I will present our novel abstrac FaaS resource model with three levels of abstraction and novel schedulers to optimize FC makespan, scalability, and resilience in federated FaaS.
