The document outlines the hybrid cloud approach using OpenNebula, emphasizing transparency for both administrators and end-users. It details how OpenNebula integrates various public cloud services such as Amazon EC2, Microsoft Azure, and IBM SoftLayer, along with the necessary configurations for each. Limitations regarding networking and image management are noted, and a series of live demos are presented for practical understanding.

3. The OpenNebula Hybrid Approach
Operative word is transparency
• For the administrator
• Both local and remote ‘hypervisors’ are
modeled as OpenNebula hosts
• For the end user
• Consumable VM Templates can be hybrid,
meaning multiple sections describing the VM
in different locations

4. The OpenNebula Hybrid Approach
Unique hybrid approach
● One OpenNebula Host can be …
● One local Hypervisor
● One Public Cloud
● One Region (EC2) / Location (AZ) /
Datacenter(SL)
● One Availability Zone
#OpenNebulaConf OpenNebula.org

5. The OpenNebula Hybrid Approach
Unique hybrid approach
● End users consume a catalog of hybrid templates
● Administrators manage
● Scheduling policies
● Fixed priority
● Public Cloud modeled capacity
#OpenNebulaConf OpenNebula.org

6. The OpenNebula Hybrid Approach
Limitations
● No ‘magic’ networking
● Define VPNs, benchmark latency
● No automatic image upload
● Admin task to preload or configure images
● … and, of course, no automatic inter-public cloud
image converting + transferring …

The image cannot be displayed. Your
computer may not have enough
memory to open the image, or the
image may have been corrupted.
Restart your computer, and then open
the file again. If the red x still appears,
you may have to delete the image and
