Federation of clouds: Multi-Clouds overflow

To cover data analytics needs, Cloud providers need to adapt their IaaS services to resources consumption fluctuations and demands. This requests geographical distribution of tasks excutions and flexible services. Having a federation of cloud providers allows to provide such services to users.

In this project, users submit their applications on a cloud broker. The aim is to find resources in one or many clouds to be able to answer the request. The ability for one cloud provider to forward a part of the execution to another one is called overflow. This can lead to some negociation between cloud providers to find solutions (some game theory could be used).

The goal of this internship is to study a multi-cloud overflow problem and simulate solutions.

This internship will:

• formalize the problem,
• explore different objectives of its optimization (energy consumption, price, quality of service…)
• explore different possible heuristics.

The project is in the context of the DATAZERO2 (http://datazero.org/ funded by ANR) project at IRIT (http://www.irit.fr) in Toulouse. For more information contact Georges Da Costa (georges.da-costa@irit.fr) and Patricia Stolf (patricia.stolf@irit.fr) of the SEPIA team. The main research topics of the SEPIA time are optimisation of datacenter (multi-objective scheduling).

Expected ability of the student

• Linear programming
• Distributed systems
• Optimization techniques
