A large portion of the OpenStack community is gathered in Austin this week for the Spring 2016 OpenStack Summit. As I’ve done at previous Summits (and other events), I’m offering to gather with other Christian believers for a brief time of prayer in the mornings before the sessions kick off each day.
Normally I get these arranged much earlier, so I apologize for not getting this out there sooner. That being said, if you’re a Christian and interested in gathering for a brief time of prayer, we will be meeting outside the Austin Convention Center at 8:30 am. We’ll meet along East 4th Street, on the convention center side of the Downtown Station.
Anyone is welcome to join us, but please note that this will be a distinctly Christian-focused and Christ-centered event.
You don’t need to RSVP or let me know you’ll be there; just feel free to stop by. I hope to see you there!
Congratulations Docker Birthday #3 App Challenge Winners!

Welcome to Technology Short Take #65! As usual, I gathered an odd collection of links and articles from around the web on key data center technologies and trends. I hope you find something useful!
Networking
- Michael Ryom has a nice (but short) article on using Log Insight along with a NetFlow proxy to help provide more detailed visibility into traffic flows between VMs on NSX logical networks.
- Brent Salisbury has an article on GoBGP, a Go-based BGP implementation. BGP seems to be emerging as an early front-runner for a standards-based control plane for software networking. Couple something like GoBGP with IPVLAN L3 (see Brent’s article) and you’ve got a new model for your data center network.
- Andy Hill has an article on doing rolling F5 upgrades using Ansible.
- Filip Verloy has an article that discusses the integration between Nuage Networks and Fortinet.
- This should probably go in the “Cloud Computing/Cloud Management” section, but the boundaries between areas are getting more and more blurry every day. (Thankfully, due to LASIK my vision is sharper than ever.) In any case, here’s a post by Marcos Hernandex on the use of subnet pools in OpenStack. Although Marcos’ post discusses them Continue reading

In an effort to make Docker Engine smaller, better, faster, stronger, we looked for components of the current engine that we can break out into separate projects and improve along the way. One of those components is the Docker runtime for … ContinuedPatching BADLOCK with Ansible
If you've been following recent security news, you may have heard of the Badlock vulnerability in the protocols used by the Microsoft Windows Active Directory infrastructure. This vulnerability could lead to a man-in-the-middle attacker intercepting traffic between a client and the Active Directory server, and then impersonating the client, gaining unauthorized access to resources.

More information can be found at http://badlock.org/ and the Red Hat Knowledgebase. |
Thanks to Ansible, however, patching your systems doesn't have to be complicated.

We love stories about how Ansible Tower has solved problems and made work easier. When we heard that CareerBuilder was using Tower in a Windows environment, we had to know more. Special thanks to Cody Rucks from CareerBuilder for sharing his story about Ansible Tower.
---
At CareerBuilder we are focused on building out a full stack solution that will allow developers to continuously deploy their applications. Not only do we want them to be able to deploy quickly, but we want consistency and automation throughout the entire process. Ansible Tower has become a huge part of our final end solution. In this post we will discuss how we are using Ansible Tower to connect our various products and steps and truly be able to deploy applications in the cloud utilizing DevOps methodologies.
Why Ansible Tower?
In November 2015, our team set out to find the best solution for our needs. We tested several different products and vendors ranging from the most buzz-worthy to the most obscure and ended up selecting Ansible Tower at the end. Ansible Tower seemed to provide all the things that we needed it to do. They key takeaways we had that made us select Ansible Continue reading
