I would like to nominate myself for the OpenStack Bare Metal Provisioning
(Ironic) PTL position.

I have been working with OpenStack for over 18 months, and was a
scalability and performance consultant at Percona for four years prior.
Since '99, I have worked as a developer, team lead, database admin, and
linux systems architect for a variety of companies.

I am the current PTL of the Bare Metal Provisioning (Ironic) program, which
began incubation during Havana. In collaboration with many fine folks from
HP, NTT Docomo, USC/ISI, and VirtualTech, I worked extensively on the Nova
Baremetal driver during the Grizzly cycle. I also helped start the TripleO
program, which relies heavily on the baremetal driver to achieve its goals.
During the Folsom cycle, I led the effort to improve Nova's DB API layer
and added devstack support for the OpenVZ driver. Through that work, I
became a member of nova-core for a time, though my attention has shifted
away from Nova more recently.

Once I had seen nova-baremetal and TripleO running in our test environment
and began to assess our longer-term goals (eg, HA, scalability, integration
with other OpenStack services), I felt very strongly that bare metal
provisioning was a separate problem domain from Nova and would be best
served with a distinct API service and a different HA framework than what
is provided by Nova. I circulated this idea during the last summit, and
then proposed it to the TC shortly thereafter.

During this development cycle, I feel that Ironic has made significant
progress. Starting from the initial "git bisect" to retain the history of
the baremetal driver, I added an initial service and RPC framework,
implemented some architectural pieces, and left a lot of #TODO's. Today,
with commits from 10 companies during Havana (*) and integration already
underway with devstack, tempest, and diskimage-builder, I believe we will
have a functional release within the Icehouse time frame.

I feel that a large part of my role as PTL has been - and continues to be -
to gather ideas from a wide array of individuals and companies interested
in bare metal provisioning, then translate those ideas into a direction for
the program that fits within the OpenStack ecosystem. Additionally, I am
often guiding compromise between the long-term goals, such as firmware
management, and the short-term needs of getting the project to a
fully-functional state. To that end, here is a brief summary of my goals
for the project in the Icehouse cycle.

* API service and client library (likely finished before the summit)
* Nova driver (blocked, depends on ironic client library)
* Finish RPC bindings for power and deploy management
* Finish merging bm-deploy-helper with Ironic's PXE driver
* PXE boot integration with Neutron
* Integrate with TripleO / TOCI for automated testing
* Migration script for existing deployments to move off the nova-baremetal
* Fault tolerance of the ironic-conductor nodes
* Translation support
* Docs, docs, docs!

Beyond this, there are many long-term goals which I would very much like to
facilitate, such as:

* hardware discovery
* better integration with SDN capable hardware
* pre-provisioning tools, eg. management of bios, firmware, and raid
config, hardware burn-in, etc.
* post-provisioning tools, eg. secure-erase
* boot from network volume
* secure boot (protect deployment against MITM attacks)
* validation of signed firmware (protect tenant against prior tenant)

Overall, I feel honored to be working with so many talented individuals
across the OpenStack community, and know that there is much more to learn
as a developer, and as a program lead.
