TechDay Frankfurt, 26 September 2018

The OpenNebula Cloud TechDays are day-long educational and networking events to learn about OpenNebula.  Join our technical experts from OpenNebula by OpenNebula Systems for a one-day, hands-on workshop on cloud installation and operation. You’ll get a comprehensive overview of OpenNebula and will be equipped with the skills to take this back to your company and implement right away.

Local Organizer

LINBIT, the makers of DRBD®, has led the way in high-availability since 2001, and continues to be the OSS market leader for continuity solutions. DRBD is the global standard for mission critical systems. DRBD9 is in OpenNebula, so it integrates seamlessly with your Private Cloud Environment and runs on commodity hardware and virtualization platforms.

Call for Speakers

Send us an email at events@opennebula.org if you are interested in speaking at this TechDay and:

  • Sharing cloud use cases and deployment experiences
  • Introducing new integrations and ecosystem developments
  • Describing other related cloud open-source projects and tools

Registration

The number of seats is limited  to ensure there is plenty of opportunity for everyone to interact. We encourage everyone to register as early as possible.

Agenda and Speakers

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

9:00-9:15: Registration

9:15-9:30: Welcome Talk

Tino Vázquez, OpenNebula Systems

VP of Engineering

9:30-12:30: Hands-on Tutorial

Sergio Semedi, 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.

Contents

  • Configuration and basic usage
  • An introduction to cloud computing with OpenNebula
  • The architecture of the cloud
  • Planning and installing OpenNebula
  • Virtualization hosts management
  • Basic datastore configuration
  • Basic virtual network creation
  • VM Template creation & instantiation

Methodology

This is an interactive course, where the attendees operate on their own labs with a 3-node OpenNebula cloud, which are provided during the course. OpenNebula provides an abstraction layer on top of the infrastructure and technologies deployed in the datacenter. In order for the attendees to get the best understanding possible of OpenNebula as a whole, the labs used during the course make use of the most common open-source technologies that can be used to deploy an OpenNebula cloud. For example, the hypervisor technology used during the course will be KVM, shared file-system for storage, and regular linux bridges and linux firewall for networking. Other technologies supported by OpenNebula will be addressed and discussed as well.

Audience

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

Prerequisites

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

Material

The instructor will rely on a set of PDF documents that will be explained throughout the course. These documents will be made available to the attendees right at the very beginning of the course. Attendees need a laptop to connect to their hands-on labs.

12:30-13:30: Lunch

13:30-16:00: Workshop

13:30 – 14:30: LINSTOR – Resilient and performant open source SDS for OpenNebula

Phil Reisner, LINBIT, CEO

The Linux kernel has a large set of very powerful storage functionalities such as LVM, thin provisioning, RAID, SSD as HDD caches, deduplication, targets/ initiators, and DRBD. They are all compatible on the data plane, but each brings its own control mechanism. LINSTOR makes use of all of these tools to build and manage block storage volumes (replicated either synchronously or asynchronously) as part of a larger storage cluster. It comes with connectors for OpenNebula and OpenStack/Cinder and Kubernetes and can be used on dedicated storage nodes or in a hyperconverged way with Linux-based OpenNebula hypervisor nodes. This approach can be really powerful for IO-intensive workloads such as databases and works well both on hyper-converged infrastructure or on dedicated storage nodes.

14:30 – 15:00: Considerations on Smart Cloud Implementations

Arne Heitmann, Mellanox, EMEA Staff System Engineer
Cloud deployments that rely on SW defined components, such as SW defined Storage, depend on a proper and efficient network implementation. This presentation discusses some aspects that help
building a reliable and performing architecture. We will have a look at how HW offloads free up resources, i.e. with VXLAN and OVS offloading and RoCE, in an end system and how the networking devices support an efficient communication.

15:00 – 15:30: Coffee Break

15:30 – 16:00: Migration as a path to Hybrid Cloud

Edwin Kuss, Hystax, Director of Sales EMEA
Edwin will be discussing the migration from VMware to Openstack using Hystax Accura and Linbit storage, as well as, the importance to have Hybrid Clouds – private & public – and possible migration and DR possibilities.

16:00-16:30: 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.
