Reaching the fork in the road

Walt Disney said it best: We keep moving forward, opening new doors, and doing new things, because we’re curious and curiosity keeps leading us down new paths. The world of technology is all about change. We tear down the old things that get in our way and we build new technology that takes us to new heights. Tearing down these old things can often be difficult and that forces us to make difficult choices....

OpenStack Summit Boston 2017 Recap

The OpenStack Summit wrapped up today in Boston and it was a great week! There were plenty of informative breakouts and some interesting keynotes. Keynotes Beth Cohen shared some of the work that Verizon has done with software-defined WAN on customer-premises equipment (CPE). She showed a demo of how customers could easily provision virtual network hardware, such as firewalls or intrusion detection systems, without waiting for hardware or cabling changes. I’m less familiar with the world of telcos, so I found this really interesting....

Five reasons why I’m excited about POWER9

There’s plenty to like about the POWER8 architecture: high speed interconnections, large (and flexible) core counts, and support for lots of memory. POWER9 provides improvements in all of these areas and it has learned some entirely new tricks as well. Here are my top five reasons for getting excited about POWER9: NVLink 2.0 In the simplext terms, NVLink provides a very high speed interface between CPUs and GPUs with very low latency....

Reflecting on 10 years of (mostly) technical blogging

It all started shortly after I joined Rackspace in December of 2006. I needed a place to dump the huge amounts of information I was learning as an entry-level Linux support technician and I wanted to store everything in a place where it could be easily shared. The blog was born! The blog now has over 700 posts on topics ranging from Linux system administration to job interview preparation. I’ll get an email or a tweet once every few weeks from someone saying: “I ran into a problem, Googled for it, and found your blog!...

Join me on Thursday to talk about OpenStack LBaaS and security hardening

If you want to learn more about load balancers and security hardening in OpenStack clouds, join me on Thursday for the Rackspace Office Hours podcast1! Walter Bentley, Kenneth Hui and I will be talking about some of the new features available in the 12.2 release of Rackspace Private Cloud powered by OpenStack. The release has a tech preview of OpenStack’s Load Balancer as a Service project. The new LBaaSv2 API is stable and makes it easy to create load balancers, add pools, and add members....

Talk recap: The friendship of OpenStack and Ansible

The 2016 Red Hat Summit is underway in San Francisco this week and I delivered a talk with Robyn Bergeron earlier today. Our talk, When flexibility met simplicity: The friendship of OpenStack and Ansible, explained how Ansible can reduce the complexity of OpenStack environments without sacrificing the flexibility that private clouds offer. The talk started at the same time as lunch began and the Partner Pavilion first opened, so we had some stiff competition for attendees' attention....

My list of must-see sessions at Red Hat Summit 2016

The Red Hat Summit starts this week in San Francisco, and a few folks asked me about the sessions that they shouldn’t miss. The schedule can be overwhelming for first timers and it can be difficult at times to discern the technical sessions from the ones that are more sales-oriented. If you’re in San Francisco, and you want to learn a bit more about using Ansible to manage OpenStack environments, come to the session that I am co-presenting with Robyn Bergeron: When flexibility met simplicity: The friendship of OpenStack and Ansible....

OpenStack Summit in Austin is almost here!

OpenStack comes home to Austin on Monday for the OpenStack Summit! I will be there with plenty of other Rackers to learn, collaborate, and share our story. If you’re interested in applying automated security hardening to an OpenStack cloud, be sure to drop by my talk on Tuesday from 11:15 to 11:55 AM. I’ll explain how Rackspace uses the openstack-ansible-security Ansible role to automatically apply hardening standards to servers in an OpenStack private cloud....

Build a high performance KVM hypervisor on Rackspace’s OnMetal servers

I received some good feedback about my post on systemd-networkd and bonded interfaces on Rackspace’s OnMetal servers, and I decided to write about another use case. Recent product updates allow you to attach a Cloud Block Storage volume, and this opens up quite a few new possibilities for deployments. So why not create a high-performance KVM hypervisor on an OnMetal server? Let’s do this. Disclaimer WHOA THERE. These are amazing servers and because of that, they’re priced much differently than Cloud Servers are....

Using systemd-networkd with bonding on Rackspace’s OnMetal servers

I’ve written about systemd-networkd in the past and how easy it can be to set up new network devices and tunnels. However, the documentation on systemd-networkd with bonding is a bit lacking (but I have a pull request pending for that). Rackspace’s OnMetal Servers are a good place to test since they have bonded networks configured by default. They’re also quite fast and always fun for experiments. To get started, head on over to the Rackspace Cloud control panel and build a compute-1 OnMetal server and choose Fedora 22 as your operating system....
