Editor's Notes
- #2 Since 2012, Comcast has experienced 400% year over year growth in demand and capacity for it’s Openstack-based Elastic Cloud service. This talk will highlight the areas where Openstack has delivered business value for Comcast and the challenges ahead in meeting the demand for more complex capabilities.
- #3 One of the largest Multi-Service Operators - MSOs in USA 10s of millions of customers 100s of millions of devices We most likely touch your home in some way or another, even if you aren’t a subscriber
- #4 We are running OpenStack in 34 regions and have more expected in the pipeline We have over 700 tenants We have 20,000 instances
- #5 Over a year ago at the Vancouver summit, we had contributed 36K lines of code towards the Kilo release of OpenStack Today we have almost 73,000 lines of code, most of our contributions have been towards documentation, Neutron and OpenStack-Ansible We are the founders of the Northern Virginia OpenStack meetup group and have 500 members and growing We participate as track chairs for the OpenStack summit We are part of the Women of OpenStack and try to contribute back to the community wherever we can
- #6 Essex – wasn’t sure it was ready for production, but our developers loved it – better than bare metal – faster to get moving – we were self service and on demand. Grizzly – discovered that upgrades sucked Havana - as the demand sky rocketed we had to learn about scaling Icehouse – very painful upgrade, took a year and a half for us to code
- #8 2016 has been a huge year for us Ops can’t do everything – separated deployments - this was our biggest win on speeding up deployments Docs are still a work in process Currently: VMs – we believe this number will at least double in 2017
- #9 2016 has been a huge year for us Ops can’t do everything – separated deployments - this was our biggest win on speeding up deployments Docs still in process Currently: VMs – we believe this number will at least double in 2017

- #11 Management call out – give thanks for the support
- #13 We’ll be at the reception later as will several members of our team that did the work we have described here, please find us if you have any questions.
