It is no accident that Xen software powers some of the largest Clouds in existence. From its outset, the Xen Project was intended to enable what we now call Cloud Computing. This session will explore how the Xen Architecture addresses the needs of the Cloud in ways which facilitate security, throughput, and agility. It will also cover some of the hot new developments of the Xen Project.

4. Stability is Paramount
Value of IT: consistent service availability
Service capacity specified a year or more in advance
What’s up, stays up
Change is Bad
Change to status quo is disruptive and dangerous
5. Availability of Services is Paramount
Value of IT: consistent service availability
matching dynamic business demand
Service capacity must move with business needs
What’s up when depends on what’s needed when
Change is Good
Services must change to cover the needs of the moment
Lack of change = lack of value
6. It must be stable
It must be secure
It must be configurable on a large scale
It must take orchestration
It must be multi-tenant

29. Not on Feature and Quality parity yet
Significant progress in Havanah / 13.2
Xen and XAPI not perceived to be Open Source
This is now different
Citrix backing of Apache CloudStack
Created “confusion” in the marketplace
Created resentment by OpenStack developers
35. Havanah 2013.2:
OpenStack support for xenserver-core
More Tests; Improved Quality (moving towards Group A)
Icehouse 2014.1
Feature catch-up (not in one go)
ARM support for xenserver-core
Expanding VGPU Functionality
Desktop and Enterprise Features
36. Impact:
OpenStack can also run in Dom0
Closer to OpenStack Usage Model
Closer to OpenStack Development Model
More Deployment Options (Security)
