Agenda and Speakers

Agenda includes a hands-on cloud installation and operation workshop, and presentations from OpenNebula community members and users.

9:00-13:00: Hands-on Workshop

Javier Fontán, OpenNebula Core Developer
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: Presentations

14:00 – 14:15: An Introduction to OpenNebula

Ignacio M. Llorente, Project Director at OpenNebula
We’re moving into a world of open cloud — where each organization can find the right cloud for its unique needs. A single cloud management platform can not be all things to all people, there will be a cloud space with several offerings focused on different environments and/or industries. The OpenNebula commitment to the open cloud flows directly out of its mission — to become the simplest cloud enabling platform — and its purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost‐effective, reliable, open enterprise clouds on existing IT infrastructure. The OpenNebula project is really vendor‐agnostic and completely driven by users needs with features that meet real demands. The session will introduce the OpenNebula project from different perspectives, ranging from its historical milestones and main contributors to its most relevant users and the size of their cloud deployments.

14:15 – 14:30: Bringing Private Cloud Computing to HPC and Science

Ignacio M. Llorente, Project Director at OpenNebula
HPC-optimized clouds provide access to flexible and elastic scientific and technical computing to solve complex problems and drive innovation. The talk will describe the most demanded features for building HPC and science clouds, and will illustrate using real-life case studies from leading research and industry organizations how OpenNebula effectively addresses these challenges of cloud usage, scheduling, security, networking and storage.

14:30 – 15:15:High-Availability HPC with OpenNebula

Eliot Eshelman,Vice President at Microway, Inc
Microway provides traditional on-premises HPC compute systems as well as hybrid HPC systems that burst into the public cloud. Eliot will describe one of Microway’s internal clusters which uses OpenNebula for High-Availability of the HPC resources. OpenNebula allows us to be more flexible and to achieve better uptime.

15:15 – 15:45: Coffee Break

15:45 – 16:15: Hyperconvergence and OpenNebula

Varadarajan Narayanan, CEO at Megam Systems Storage is often the bottle neck for virtualised infrastructure where customer is locked in with proprietary and expensive SAN like solutions. Hyperconvergence seems to be promising where commodity hardware can be used to provide scalable , fault tolerant infrastructure. Combining Opennebula platform with a distributed storage solution bundled with  caching with high speed SSDs seems to be good idea to offer a high performance hyperconvergent  solution. Pros and cons of distributed and centralised storage systems and performance comparison are studied here.

16:15 – 16:45: Future of Information Storage with ISS SuperCore and Ceph

 Alex Gorbachev, Intelligent Systems Services Inc. The time is ripe for high speed resilient software defined storage solutions with unlimited scalability. ISS has been working with the leading open source projects and developed a commercial high performance solution that is able to grow forever without performance limitations. In the session we will share foundation principles of Ceph architecture, as well as our design to deliver this storage to traditional SAN storage consumers.

16:45 – 17:00
: Open Space

This is a session for attendees to gather and discuss passionate questions, burning ideas, features, integrations or any topic of their choice, in an informal and tech-friendly environment, with other passionate and interested people. There is no preplanned list of topics, only time slots and a space in one of the meeting rooms where interested participants propose topics and pick time slots.
