9:00-13:00: Hands-on Tutorial

Jaime Melis, OpenNebula Systems This hands-on tutorial will give an overview of how OpenNebula is used to build and operate private clouds. The attendees will build, configure and operate their own OpenNebula cloud.


  • An introduction to cloud computing with OpenNebula
  • The architecture of the cloud
  • Planning and installing OpenNebula
  • Configuration and basic usage


The target audience is devops and system administrators interested in deploying a private cloud solution, or in the integration of OpenNebula with other platform.

Skills Gained

  • Describe the features and benefits of using virtualization and clouds
  • Describe different architectures for a cloud that can be deployed with OpenNebula
  • Deployment and basic configuration OpenNebula
  • Basic operation of an OpenNebula cloud instance


No prior OpenNebula skills are required, but participants should have working knowledge of virtualization, networking and Unix/Linux systems.


The workshop includes hands-on exercises to be performed using attendee’s wifi-enabled laptops with VirtualBox installed. The attendees will build, configure and operate their own OpenNebula cloud.

13:00-14:00: Lunch

14:00 – 17:00: Workshop

14:00 – 14:30:OpenNebula out in the Open

Ander Astudillo, SURFsara
Where OpenNebula is typically used by system administrators to manage data centers, SURFsara’s HPC Cloud exposes OpenNebula’s web interface crudely to end users. SURFsara’s end users are researchers. They all have diverse needs and most of them are no system experts. It turns out that OpenNebula’s interface is easy enough to use, enabling researchers to build complex compute infrastructures for their analysis workflows. This presentation discusses the features our researchers and we appreciate in OpenNebula, it pictures a selection of succesful projects and it also explains caveats we have come across while keeping the service in the air.
