Looking to Leverage OpenStack Havana? Crowbar delivers 3xL!

openstack_havanaThe Crowbar community has a tradition of “day zero ops” community support for the latest OpenStack release at the summit using our pull-from-source capability.  This release we’ve really gone the extra mile by doing it one THREE Linux distros (Ubuntu, RHEL & SLES) in parallel with a significant number of projects and new capabilities included.

I’m especially excited about Crowbar implementation of Havana Docker support which required advanced configuration with Nova and Glance.  The community also added Heat and Celiometer in the last release cycle plus High Availability (“Titanium”) deployment work is in active development.  Did I mention that Crowbar is rocking OpenStack deployments?  No, because it’s redundant to mention that.  We’ll upload ISOs of this work for easy access later in the week.

While my team at Dell remains a significant contributor to this work, I’m proud to point out to SUSE Cloud leadership and contributions also (including the new Ceph barclamp & integration).  Crowbar has become a true multi-party framework!

 

Want to learn more?  If you’re in Hong Kong, we are hosting a Crowbar Developer Community Meetup on Monday, November 4, 2013, 9:00 AM to 12:00 PM (HKT) in the SkyCity Marriott SkyZone Meeting Room.  Dell, dotCloud/Docker, SUSE and others will lead a lively technical session to review and discuss the latest updates, advantages and future plans for the Crowbar Operations Platform. You can expect to see some live code demos, and participate in a review of the results of a recent Crowbar 2 hackathon.  Confirm your seat here – space is limited!  (I expect that we’ll also stream this event using Google Hangout, watch Twitter #Crowbar for the feed)

My team at Dell has a significant presence at the OpenStack Summit in Hong Kong (details about activities including sponsored parties).  Be sure to seek out my fellow OpenStack Board Member Joseph George, Dell OpenStack Product Manager Kamesh Pemmaraju and Enstratius/Dell Multi-Cloud Manager Founder George Reese.

Note: The work referenced in this post is about Crowbar v1.  We’ve also reached critical milestones with Crowbar v2 and will begin implementing Havana on that platform shortly.

OpenStack Havana provides foundation for XXaaS you need

Folsom SummitIt’s been a long time, and a lot of summits, since I posted how OpenStack was ready for workloads (back in Cactus!).  We’ve seen remarkable growth of both the platform technology and the community surrounding it.  So much growth that now we’re struggling to define “what is core” for the project and I’m proud be on the Foundation Board helping to lead that charge.

So what’s exciting in Havana?

There’s a lot I am excited about in the latest OpenStack release.

Complete Split of Compute / Storage / Network services

In the beginning, OpenStack IaaS was one service (Nova).  We’ve been breaking that monolith into distinct concerns (Compute, Network, Storage) for the last several releases and I think Havana is the first release where all of the three of the services are robust enough to take production workloads.

This is a major milestone for OpenStack because knowledge that the APIs were changing inhibited adoption.

ENABLING TECH INTEGRATION: Docker & Ceph

We’ve been hanging out with the Ceph and Docker teams, so you can expect to see some interesting.  These two are proof of the a fallacy that only OpenStack projects are critical to OpenStack because neither of these technologies are moving under the official OpenStack umbrella.  I am looking forward to seeing both have dramatic impacts in how cloud deployments.

Docker promises to make Linux Containers (LXC) more portable and easier to use.  This paravirtualization approach provides near bear metal performance without compromising VM portability.  More importantly, you can oversubscribe LXC much more than VMs.  This allows you to dramatically improve system utilization and unlocks some other interesting quality of service tricks.

Ceph is showing signs of becoming the scale out storage king.  Beyond its solid data dispersion algorithm, a key aspect of its mojo is that is delivers both block and object storage.  I’ve seen a lot of interest in consolidating both types of storage into a single service.  Ceph delivers on that plus performance and cost.  It’s a real winner.

Crowbar Integration & High Availability Configuration!

We’ve been making amazing strides in the Crowbar + OpenStack integration!  As usual, we’re planning our zero day community build (on the “Roxy” branch) to get people started thinking about operationalizing OpenStack.   This is going to be especially interesting because we’re introducing it first on Crowbar 1 with plans to quickly migrate to Crowbar 2 where we can leverage the attribute injection pattern that OpenStack cookbooks also use.  Ultimately, we expect those efforts to converge.  The fact that Dell is putting reference implementations of HA deployment best practices into the open community is a major win for OpenStack.

Tests, Tests, Tests & Continuous Delivery

OpenStack continue to drive higher standards for reviews, integration and testing.  I’m especially excited to the volume and activity around our review system (although backlogs in reviews are challenges).  In addition, the community continues to invest in the test suites like the Tempest project.  These are direct benefits to operators beyond simple code quality.  Our team uses Tempest to baseline field deployments.  This means that OpenStack test suites help validate live deployments, not just lab configurations.

We achieve a greater level of quality when we gate code check-ins on tests that matter to real deployments.   In fact, that premise is the basis for our “what is core” process.  It also means that more operators can choose to deploy OpenStack continuously from trunk (which I consider to be a best practice scale ops).

Where did we fall short?

With growth comes challenges, Havana is most complex release yet.  The number of projects that are part the OpenStack integrated release family continues to expand.  While these new projects show the powerful innovation engine at work with OpenStack, they also make the project larger and more difficult to comprehend (especially for n00bs).  We continue to invest in Crowbar as a way to serve the community by making OpenStack more accessible and providing open best practices.

We are still struggling to resolve questions about interoperability (defining core should help) and portability.  We spent a lot of time at the last two summits on interoperability, but I don’t feel like we are much closer than before.  Hopefully, progress on Core will break the log jam.

Looking ahead to Ice House?

I and many leaders from Dell will be at the Ice House Summit in Hong Kong listening and learning.

The top of my list is the family of XXaaS services (Database aaS, Load Balanacer aaS, Firewall aaS, etc) that have appeared.  I’m a firm believer that clouds are more than compute+network+storage.  With a stable core, OpenStack is ready to expand into essential platform services.

If you are at the summit, please join Dell (my employer) and Intel for the OpenStack Summit Welcome Reception (RSVP!) kickoff networking and social event on Tuesday November 5, 2013 from 6:30 – 8:30pm at the SkyBistro in the SkyCity Marriott.   My teammate, Kamesh Pemmaraju, has a complete list of all Dell the panels and events.
