Xen.org has several initiatives that aim to have an impact onOpenStack adoption and feature richness. This talk will include adiscussion on the Xen Cloud Platform (XCP), the XCP toolstack (XAPI)port to popular Linux distributions, and the Xen on ARM initiative. XCP combines the Xen hypervisor with enhanced security, storage, andnetwork virtualization technologies to offer a rich set of virtualinfrastructure cloud services. These XCP cloud services can beleveraged by OpenStack cloud providers to enable isolation andmulti-tenancy capabilities in their environments. XCP also providesthe user requirements of security, availability, performance, andisolation for private and public OpenStack cloud deployments. Xen.org is working to make XCP and OpenStack work seamlessly so thattogether they can be the ultimate open source cloud solution. Inaddition to deploying XCP as a separate component with OpenStack,Xen.org is simultaneously porting the XCP toolstack (XAPI) to Linuxdistributions, which will give cloud administrators an easy-to-installOpenStack and Xen-based integrated alternative. Finally, industry thought leaders, such as Mark Shuttleworth, aresupporting the adoption of ARM in server-class systems. Consequently,the port of Xen to the ARM platform could make it possible forOpenStack and Xen to lead the way into the future of ARM-based clouddeployments.
