Cloudlab Testbed

This document will introduce you to the Cloudlab testbed and it will walk you through step-by-step how to sign-in to the Cloudlab testbed using your Onelab credentials, to reserve resources and to start an experiment. This document will mainly cover the Onelab part of Cloudlab. For advanced usage, please refer to the main Cloudlab documentation

  1. What is Cloudlab ?: We will begin by introducing you Cloudlab and how it is connected to Onelab
  2. How to sign-in: This step will show you how to sign-in to Cloudlab Portal using your Onelab credentials
  3. How to start an experiment: In this stage, you will learn how to start an experiment and allocate resource to it.
  4. How to login to your allocated resources via SSH: Once your experiment is set up, you will need to access your resources. This step will tell how to access and manage your resources.


Cloudlab is a meta-cloud or more precisely it’s a facility to build clouds. It provides bare-metal access and control over a substantial set of computing, storage and networking resources to users. Users can install new, existing or modified cloud software stacks and test them using this facility.

Cloudlab is now fully integrated into Onelab, thus, you can login and reserve Cloudlab resources using your Onelab credentials. On top of that, Onelab has deployed, in its own infrastructure at Paris, ARM servers (m400 nodes) that are dedicated to the Cloudlab testbed.
