State of the project

• Under development

• Proof of concepts

• Scale coming

Why Hybrid Cloud?

Hybrid Cloud Challenges

• Networkingo Nodes on the public cloud should look like they are on the

private network• Local and remote capacity, configuration• Hardware life cycle management dependent on:

o hypervisor versions and families o disk and image formats

• Where does the data live?

Enabling Technologies

• OpenStack - Orchestration• Open vSwitch - Network Virtualization• Xen Cloud Platform (XCP) and XenServer

Federation and Zones

• A Zone is a container for compute resources• Zones can have any number of hypervisors

Simple Zone

MultiZone

MultiZone

Challenges with Zones

• Inconsistent sizes (flavors) of offerings• Different network topologies may not work for all apps• Allows for specialization (GPU, high cpu, network, etc)

Quantum and Open vSwitch

• Network as a Service used by Nova• Currently under heavy development• Isolation from neighbors

Current and Future Issues

• Hybrid Networkingo Maintaining network connections during hybrid cloud

moveo Open vSwitch implementation expected in Diablo

• Hybrid File Formatso Maintaining backing storage during hybrid cloud moveo Open Virtualization Format (OVF)
