Congrats to OpenStack – Havana delivers on enterprise readiness


It’s amazing how time flies. It seems like yesterday we helped launch the OpenStack Foundation. Now, here we are celebrating OpenStack’s most significant release to date: Havana.

OpenStack’s strong governance and meritocracy-based development process have proven their worth in this latest release, which is packed with enhancements to support even the largest enterprise user.

New functionality supporting security, metering, monitoring, quality assurance and enhanced version-to-version upgrades leave no doubt that OpenStack is ready for enterprise adoption. IBM is very proud to have been a top contributor over the past two releases of OpenStack, and we would like to give you a sneak peak into some of the key features of this latest release.

Havana addresses some of the most daunting questions facing adopters related to security, namely, “Will my data be safe on the Cloud?” and “Will my enterprise security integrate with OpenStack?” These are the things that keep enterprise executives awake at night and often have a direct impact on the rate of adoption.

Collaborating with other members of the OpenStack Keystone project team, IBM contributed enhancements that address key enterprise security requirements in the areas of Lightweight Directory Access Protocol (LDAP) and Active Directory integration, Transport Layer Security support, OAuth extensions and Federated Identity. These enhancements will enable enterprise users to integrate OpenStack Keystone with their existing standards-based identity management infrastructure. To learn more about OpenStack’s enhanced LDAP integration capabilities, be sure to check out this devWorks article by two of the engineers that collaborated on the new features.

If security is a top concern for enterprise users, it’s likely that the second most important concern is the ability to measure, monitor and audit usage of enterprise cloud solutions. One of the newer core projects in OpenStack is Ceilometer, a metering and monitoring project. Ceilometer enables real-time monitoring and metering of OpenStack services and usage. Enterprises can then optimize cloud resources and plan for future growth by using analytics on the information collected by Ceilometer.

Trend analysis can be used to estimate when critical resources may run out and the cloud dashboards can be used to manage cloud environments from either desktop browsers or via mobile devices. What you might not know about Ceilometer is that it is based on open standards, as the Ceilometer project implements the DMTF’s Cloud Auditing Data Federation (CADF) standard as part of this latest OpenStack release. Implementation of CADF helps protect the investments of companies seeking to move their applications to cloud deployment models and preserve their ability to audit operational processes, regardless of their chosen cloud provider.

For the OpenStack community to claim “enterprise-readiness,” it’s critically important that we be relentless on the topic of quality. The mission of the QA team is to develop, maintain and initiate tools and plans to ensure OpenStack’s upstream stability and quality, and its release readiness at any point during the release cycle. In the Havana release, one of the biggest enhancements to celebrate is support for parallel testing.

This may sound simple, but this means that every proposed merge or change is now running in a simulated testing environment that looks like a real OpenStack environment. By testing in a real cloud environment, enterprise users will have the overall assuredness that OpenStack components have been tested under a much higher level of stress in order to identify issues which could normally only be identified by large testing environments. The bottom line benefit here for users? With Havana, the overall experience for all users—including enterprises—will be much more stable.

Given that OpenStack releases are delivered twice a year, the upgrade experience from one version to the next is obviously very important to enterprise users. This is the final area of enhancements that I would like to highlight as you all embark on your upgrade path to Havana. The latest upgrade enhancements to Havana introduce the ability to test every change and ensure that it is upgrade friendly. If configurations can’t pass all tests, changes are considered incompatible and are prevented. Because of these new enhancements, enterprise administrators will find the upgrade path from Grizzly to Havana to be much simpler.

This is just a small preview of goodies for enterprise users in today’s Havana release.  Please join us at the next OpenStack Summit in Hong Kong November 5-8 for a more in-depth look.

As a headline sponsor, IBM’s keynote on November 5th will focus on the importance of OpenStack as part of an Open Cloud Architecture and our booth will be chock full of demonstrations around SmartCloud Entry, SmartCloud Orchestrator, PowerVC and SoftLayer all running on OpenStack. Stop by our booth to learn more about IBM’s SmartCloud Orchestrator, which is built on OpenStack and provides an open and extensible cloud management platform for managing heterogeneous hybrid environments. See the OpenStack Summit website for more information –

See you in Hong Kong!

    It would be nice to know how to implement federated IaM through cutomer SSO to scale multi-tenant securely.
