CominLabs EPOC project (2013-2017)

Participants : Sabbir Hasan Rochi, Yunbo Li, Anne-Cécile Orgerie, Jean-Louis Pazat.

In this project, partners aim at focusing on energy-aware task execution from the hardware to application's components in the context of a mono-site data center (all resources are in the same physical location) which is connected to the regular electric Grid and to renewable energy sources (such as windmills or solar cells). In this context, we tackle three major challenges:

  • Optimizing the energy consumption of distributed infrastructures and service compositions in the presence of ever more dynamic service applications and ever more stringent availability requirements for services.

  • Designing a clever cloud's resource management which takes advantage of renewable energy availability to perform opportunistic tasks, then exploring the trade-off between energy saving and performance aspects in large-scale distributed systems.

  • Investigating energy-aware optical ultra high-speed interconnection networks to exchange large volumes of data (VM memory and storage) over very short periods of time.

Sabbir Hasan Rochi has defended his PhD on SLA driven Cloud autoscaling for optimizing energy footprint on May 3rd, 2017. Yunbo Li has defended his PhD on Resource allocation in a Cloud partially powered by renewable sources on June 12th, 2017.

INDIC - Cybersecurity Pole of Excellence (2014-2020)

Participants : Anna Giannakou, Christine Morin, Jean-Louis Pazat, Louis Rilling, Amir Teshome Wonjiga, Clément El Baz.

Our study carried out in the framework of a collaboration with DGA-MI aims at defining and enforcing SLA for security monitoring of virtualized information systems. To this aim we study three topics:

  • defining relevant SLA terms for security monitoring,

  • enforcing and evaluating SLA terms,

  • making the SLA terms enforcement mechanisms self-adaptable to cope with the dynamic nature of clouds.

The considered enforcement and evaluation mechanisms should have a minimal impact on performance. The funding from DGA funds two PhD students: Anna Giannakou and Amir Teshome Wonjiga. Clément El Baz is partially funded by the Brittany Regional Council in the PEC framework.
