Context

Financial and working environment

This post-doctoral position is part of the PEPR Cloud - Taranis project funded by the French government (France 2030). The position will be recruited and hosted at the Inria Center at Rennes University; and the work will be carried out within the MAGELLAN team in close collaboration with the DiverSE team and other partners in the Taranis project.

Assignment

Context:

The mutual low-latency objective for both Data Stream Processing (DSP) and Fog environments has resulted in a continuous growth of DSP deployments on Fogs [1]. However, the success of the deployment and running of stream data applications in the Fog relies on how to efficiently allocate resources and schedule tasks (operators) to achieve the desired performance. Previous efforts on deploying stream data applications in the Fog have focused on reducing the volume of communication overhead between nodes (inter-node communication) and dividing the computation between Fog servers and Clouds [2, 3]. Unfortunately, they are oblivious to (1) the dynamic nature of data streams (i.e., data volatility and bursts) and to (2) the bandwidth and resource heterogeneity in the Fog, which negatively affects the performance of stream data applications [4][5].

Objectives:

The goal of this postdoc project is to investigate how to optimize resource and task allocation when deploying data streaming processing applications in the Fog. In particular, we want to investigate new optimization metrics and objectives when deploying streaming processing applications in the Fog, including latency, throughput, and maximum sustainable throughput. Accordingly, we will develop a new scheduling framework that relies, among others, on Machine Learning/Deep Learning models to decide on resource allocation and operator placement at runtime (based on the collected data and given the cost model of redeployment and process migration). The proposed framework will be integrated in one of state-of the art data stream engines such as Flick [6], Storm [7] or Spark [8] and evaluated at large-scale using syntactic applications and real-world stream data application.
