What is Hybrid Cloud? Private Datacenter Public Datacenter

State of the project Under development Proof of concepts Scale coming

Why Hybrid Cloud? Private Datacenter Public Datacenter

Hybrid Cloud Challenges Networking o 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

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

OVS and XCP

Static Network Config Service Public

Dynamic Network Config Service Public Private

Dynamic Network Config

Solved Problems and Demo Current Progress o XCP/XenServer + OpenStack Virtual Appliance  Seamless management of private and public cloud o Demo

Current and Future Issues Hybrid Networking o Maintaining network connections during hybrid cloud move o Open vSwitch implementation expected in Diablo Hybrid File Formats o Maintaining backing storage during hybrid cloud move o Open Virtualization Format (OVF)

Conclusion Reasons behind success o Open Source o Open Standards o Collaboration  incredible ecosystem around a real open cloud project How you can get involved o OpenStack - openstack.org o XCP - xen.org
