I’m literally soaking my feet right now. I definitely wore the wrong shoes to be working a booth the whole time.
I had a hardware failure on one of my systems for the demo. Why couldn’t it have been one of the easily re-installable hypervisors? No, it had to be the fully synchronized System Engine VM. I considered asking if I could request everyone stop using their WiFi so I could sync the 17GB I needed. Demo fail always tries to get me. But I wasn’t going down without a fight.
I switched to plan B: playing a recorded video while I rebuilt it. It took some elbow grease, but the demo went well. Summit was a blur, but I had some great conversations with customers, coworkers and friends.
I’m really excited about CloudForms. In my recorded demo I showed a RHEL 2-node active/passive cluster with GFS off an iSCSI target. Then I moved all the underlying CloudForms Cloud Engine components to shared storage. I was able to launch instances, fail over Cloud Engine, and see the correct status. After managing the instances, fail back, and all was good. All of this works because the RHEL HA cluster stops the databases and other services first, moves the floating ip over, then starts the services on the active node. This was a very basic deployment, much more could be explored with clustered PostgreSQL and sharded Mongo.
In the demo booth at Summit I showed customers what CloudForms is, how to walk through a typical workflow, and demonstrated launching a 4-node JBoss cluster based on Scott Collier’s great Reference Architecture: http://www.redhat.com/resourcelibrary/reference-architectures/deploying-red-hat-openshift-enterprise-paas-for-itops which I had the pleasure of technical reviewing. I had a local RHEV 3.0 datacenter. I wanted to add a VMware vSphere 5.0 environment too, but it didn’t support the laptop NIC, so I settled for 2 RHEL systems attached to RHEV. I know I’m biased, but the snapshot method RHEV uses is exponentially faster as more instances are launched simultaneously. Boot time of 4 instances (2GB ram each) was under 3 minutes. On my enterprise class lab hardware, just 6 nodes takes about 8 minutes to fully copy and deploy on vSphere 5.0 due to the way each VM is copied from the template. I also had my EC2 account connected, and launched instances in both environments.
So, what exactly is CloudForms? The core focus is on lifecycle management of virtual machines. However, rather than attempting to displace existing virtualization management infrastructure, CloudForms acts as an abstraction layer above virtualization and uses deltacloud to interact with VMware vCenter, RHEV Manager, or Amazon EC2. This means customers aren’t asked to waste any investments in infrastructure. Virtual machines deployed by CloudForms are referred to as instances. One or more instances can be deployed from CloudForms and managed as a single entity and are referred to as applications. The user that launches the applications can choose which infrastructure to launch on. CloudForms has three major components:
- CloudForms System Engine – manages content, image definitions, and software updates – based on the upstream Katello http://katello.org/
- CloudForms Cloud Engine – manages the lifecycle of images, instances, and applications – based on the upstream Aeolus http://aeolusproject.org/
- CloudForms Config Server – provides post-boot configuration for instances – based on the upstream Audrey http://aeolusproject.org/audrey.html

I’ll post a link to my video once I figure out where to put it.
Thanks for everyone who came to Summit. Fenway Park was a blast, the weather in Boston is wonderful compared to Austin.
Update: I’ve uploaded my video until I get get some better intro/outtro on it, at which point I’ll make a separate post: http://people.redhat.com/vvaldez/videos/summit-2012/
 CloudForms 1.0 supports VMware vSphere 4+/5+, Red Hat Enterprise Virtualization 3.0+, and Amazon EC2. Support for more virtualization environments are in the works.
