The Xen Hypervisor was built for the Cloud from the outset: when Xen was designed, we anticipated a world, which today is known as cloud computing. Today, 10 years after the project started, Xen powers the largest clouds in production.
This talk explores success criteria, architecture, trade-offs and challenges for cloudy hypervisors. It is intended for users and developers and starts with a brief introduction to Xen and XCP, their architecture, common challenges for KVM and Xen and securing the cloud. It will introduce concepts such as the virtualization spectrum, the concept of domain disaggregation and the Xen Security Modules as techniques to increase security, robustness and scalability. All important factors for building clouds at scale.
The talk will conclude with exciting developments in the Xen community, such as Xen support for ARM servers, Mirage appliances that can be run on any Xen based cloud, etc. and explore their implications for building open source clouds.
