Don’t Repeat Our Mistakes! Lessons Learned from Running Go Daddy’s Private Cloud (OpenStack Queens Summit)

Slides from our talk at the OpenStack Queens Summit in Sydney, Australia in November 2017.  The video is also posted here. Don’t Repeat Our Mistakes! Lessons Learned from Running Go Daddy’s Private Cloud (OpenStack Sydney Summit) from Mike Dorman

Finally! A workaround for LLDP with Open vSwitch

Like many OpenStack operators, we use Open vSwitch on our hypervisors.  Unfortunately, when running Open vSwitch, you lose some ability to do some functions on the lower level physical interfaces on the box (packet flows do not pass through the regular netfilter path in the kernel, for example.)  This has a side effect of LLDP

Collecting Events from Multiple RabbitMQ Clusters with Ceilometer

(Note: Credit goes to Sam Morrison at NeCTAR for passing this tip on to us!) We use the Ceilometer notification agent to collect notification events from the various OpenStack services, and then republish those events to a Kafka cluster.  Those events are consumed by other teams within the company that want to be notified about

Corrugated Steel Garden Boxes

CentOS 6 to 7 Upgrades for OpenStack Hypervisor Hosts

Nova Cells v1 Support for Server Groups

In a previous post, I described how we implemented Nova Cells v1 support for server group objects using MySQL triggers.  We’d been running that for a while, but needed a real solution (mostly because we created a new cell whose database was in on a different MySQL server.) The patch for Nova is here, and

Duct Tape, Bubble Gum, and Bailing Wire (OpenStack Mitaka Summit, Tokyo)

Here’s a fun talk I did with Matt Fischer, Eric Peterson, and Kris Lindgren at the Tokyo summit. This lightning round talk will present various operators horror stories on weird things needed to keep OpenStack running.  Audience participation is almost assured as we share feats of strength and airing of grievances.

OpenStack Architecture at Go Daddy

We have given a few “show and tell” talks at the last summits and operators’ meetups about the OpenStack architecture we’re running at Go Daddy. We thought we’d some more in-depth posts to dive into it further.

OpenStack Architecture at Go Daddy, Part 2: Neutron

As mentioned previously we do some customizations in Neutron in order to support our layer 3 networking model.  There are no tenant networks, tunneling or overlays.

OpenStack Architecture at Go Daddy, Part 3: Nova

After our first two posts detailing OpenStack architecture at Go Daddy, this third one in the series focuses on Nova.
