“OpenStack has crossed the
threshold and will become another
de facto IaaS standard before the
end of the year, when OpenStack
compatibility will be a must, not a
nice-to-have.”

Key Themes Across the Community
Voice of the user continues to shape software
• Users contribute code for real world use cases to solve issues
they see day to day
• New opportunities for users to influence roadmap
Many users finding the right path to adoption for their
business
• One size does not fit all: that’s why OpenStack is the right
choice for so many
• Vibrant ecosystem offers everything from escalation support
and training to packaged distributions, turn-key deployment
and public cloud services
Testing/Reliability requirements continue to rise
• Rigorous testing now a requirement across projects
• Strict criteria to be part of the integrated release, need test
coverage and CI

How Icehouse Delivers What Users Want
Upgrades without
downtime
Rolling upgrades with no impact to user
workloads
Consistent
experience across
drivers
Rigorous testing and higher standards for
driver support; 53 external CI systems
testing OpenStack compatibility across
broad sets of hardware and software
configurations
Use public & private
cloud with a single ID
New federated identity allows users to
access public and private clouds with the
same credentials
One OpenStack
platform
More consistent user experience across
projects and better integration like boot
process reliability between Compute and
Networking
User requests Icehouse delivers

New Features by Category

8. 8
Compute
Improved upgrade support
• Rolling upgrades
• No impact to user workloads
Testing requirements enhanced
• All included third-party drivers fully tested
• Upgrade testing for all contributions
Other updates
• Improved scheduler performance
• Boot process reliability across platform services
• More features exposed to end users via API updates, such as
ability to target machines by affinity
• More efficient access to data layer; improves performance,
especially at scale

9. 9
Storage
Object Storage
• Discoverability: major update, ability to ask any Object
Storage cloud what capabilities are available
• New replication process significantly improves performance;
data is more efficiently transported through new s-sync
(instead of r-sync)
• Major storage policies feature in progress and coming in Juno
Block Storage
• Backend migration with tiered storage environments, allowing
for performance management in heterogeneous
environments
• Testing for external drivers to ensure API consistency across
storage platforms
• Scalability improvements with fully distributed services

10. 10
Networking
Tighter integration with Compute
• State managed across Compute and Networking provisioning
actions
• Improved consistency with instance creation
Driver testing and cross-service testing
• Better functional testing for actions that require coordination
between multiple services
• Third-party driver testing ensures consistency and reliability
across network implementations
Focus on scale and feature parity with nova-network
• Both networking options still available

11. 11
Shared Services
• Identity service: Federated authentication with the
addition of Shibboleth
• Orchestration: Ability to delegate full range of
Orchestration capabilities to users; additional native
autoscaling resources available; alignment of OASIS
TOSCA standard with HOT Orchestration
• Telemetry: Rest API to access stored events
implemented
• Dashboard: Design updated and user experience
improvements (e.g. in-line editing); now supports 16
languages with the addition of Serbian, Hindi and
German in the Icehouse release
• Database Service: New capability included in the
integrated release, allows management of relational
database services in an OpenStack environment

12. 12
The OpenStack model encourages innovation around a stable
integrated release. Looking forward to Juno, coming in October
2014:
Incubated projects
• Bare metal (Ironic)
• Data Processing (Sahara)
• Messaging (Marconi)
Looking forward to the next release: Juno

“Software is eating the world” - The Enterprise Shift
• Software is now strategic to all companies.
Successful enterprises must become tech
companies regardless of industry type, or they’ll
go the way of the dinosaur.
• This changes everything. How software is
produced & consumed, as well as the talent war,
because you can’t buy strategy in a box.
• Moving at the speed of cloud means minutes
instead of months to provision app resources.
• OpenStack is an enabling technology for the
shift, but also is a diverse community with an
open design process which welcomes users to
set the roadmap.
• The Icehouse release reflects this trend.
