Agenda

● Challenges of IT efficiency● Ubuntu OpenStack● Ubuntu 14.04 new features

Thought for the day:

Facebook took 10 years and several $100M to scale to 1B users.

The next 2 web apps to scale to 1B users will do so in under 3 years on seed funding with <100 employees

What do you think smart infrastructure looks like?

You Google

Efficiency?

PUE & DCiE: Efficiency of power delivery

Silicon efficiency:

Reduction of power bill

Space efficiency:

Reduction of space bill

Efficiency

Automated scale out is the key to helping you be more like Google

OpenStack: The kernel of “Linux at scale”

OpenStack

Bare metal provisioning

Options:

● MAAS● Ironic● Razor● Custom hacks with a lot of scripting

Challenge #1

Lets use MAAS to provision systems and build an OpenStack cloud

Demo…...

Rapid provisioning at cloud scale3-step provisioning process

Install MAAS on first server

Discover Nodes

Power on Nodes

Automatically discover nodes

Enlist nodes via PXE boot

or manually enter MAC addresses

Hypervisor or OS

Adds temporary IPMI MAAS credentials to BMC

Boot in a ephemeral environment

Hardware inventoried

Permanent IPMI MAAS credentials set in BMC

Other user-commissioning actions

(firmware configuration, smoke tests, etc.)

Happens when a node is requested

Installs requested Ubuntu version

Large Asian company building public cloud

1000+ nodes split across 3 availability zonesUbuntu 12.04.1, Ubuntu 12.04.4MAAS via IPMI and Intel AMT

Challenges with AMT using shared network interface

Extensive testing of backup/recovery of MAAS across availability zones

IronicStarted May 2013

Development of nova barmetal driver

100% focused on baremetal provisioning for OpenStack

Uses Ironic API to talk to Nova

Ironic Conductor talks with Neutron, glance, cinder etc..

Ironic conductor talks to physical infrastructure

Supports 3 driver models today - PXE, IPMI, SSH

Lacking auto discovery atm.Used by HP but little outside of that for time being.
