Energy measurement

Participants : David Margery, Maxence Dunnewind, Nicolas Lebreton.

In the context of the ECO${}_2$Clouds project, the BonFIRE infrastructure was updated. At the hardware level power distribution units that report electricity usage for each outlet were installed. At the software layer, a probe reporting energy sources used was configured. This probe gets its information from RTE, the French Electricity transport network, and allows publication of CO${}_2$ metrics for each machine in the testbed. Moreover, access to these metrics was abstracted through the general API to access BonFIRE.

Deployment of IaaS management system

Participant : Alexandra Carpen-Amarie.

The Grid'5000 platform has become one of the most complete testbeds for designing or evaluating large-scale distributed systems, playing an essential role in enabling experimental research at all levels of the Cloud Computing stack and providing configurable cloud platforms similar to commercially available clouds.

However, the complexity of managing the deployment and tuning of large-scale private clouds emerged as a major drawback. Typically, users study specific cloud components or carry out experiments involving applications running in cloud environments. A key requirement in this context is seamless access to ready-to-use cloud platforms, as well as full control of the deployment settings.

To address these needs, we developed a set of deployment tools for open-source IaaS environments, capable of installing and tuning fully-functional clouds on the Grid'5000 testbed  [20] . The deployment tools support four widely-used IaaS clouds, namely OpenNebula, CloudStack, Nimbus and OpenStack.

They rely on the concept of extensible engines for defining experiments. Such engines implement all the stages of an experiment: physical node reservations in Grid'5000, environment deployment, configuration and experiment execution. We designed generic engines for nodes reservation and deployment according to a set of requirements specified in a cloud configuration file. Thus, these engines do not require any prior knowledge of lower-level Grid'5000 tools, allowing the user to easily achieve multi-site Grid'5000 deployments based on multiple environments.

BonFIRE

Participants : Maxence Dunnewind, David Margery, Eric Poupart.

The project was reviewed in December 2013 during CloudCom 2013 in Bristol and rated Excellent. The main achievement this year is the introduction of a reservation system for resources on the BonFIRE platform.

Fed4FIRE

Participants : Julien Lefeuvre, Nicolas Lebreton, David Margery.

In Fed4FIRE, two key technologies have been adopted as common protocols to enable experimenter to interact with testbeds. SFA, to provision resources, and OMF to control them. Here, we contributed to a proposal to secure usage of OMF and to a design to allow using BonFIRE through SFA.
