(BigData 2020) Big Data Applications on Large-Scale Infrastructures

Abstract: For a range of major scientific computing challenges that span fundamental and applied science, the deployment of Big Data Applications on a large-scale system, such as an internal or external cloud, a cluster or even distributed public resources ("crowd computing"), needs to be offered with guarantees of predictable performance and utilization cost. Currently, however, this is not possible, because scientific communities lack the technology, both at the level of modelling and analytics, which identifies the key characteristics of BDAs and their impact on performance. There is also little data or simulations available that address the role of the system operation and infrastructure in defining overall performance. Our vision is to fill this gap by producing a deeper understanding of how to optimize the deployment of Big Data Applications on hybrid large-scale infrastructures. Our objective is the optimal deployment of BDAs that run on systems operating on large infrastructures, in order to achieve optimal performance, while taking into account running costs. We describe a methodology to achieve this vision. The methodology starts with the modeling and profiling of applications, as well as with the exploration of alternative systems for their execution, which are hybridization's of cloud, cluster and crowd. It continues with the employment of predictions to create schemes for performance optimization with respect to cost limitations for system utilization. The schemes can accommodate execution by adapting, i.e. extend or change, the system.
