Worth Reading: LinkedIn’s Ambry
The overall design of Ambry should look fairly familiar. There are frontend servers that handle incoming requests (there are just three operations: put, get, and delete) and route them to backend data nodes which store the actual data. A ZooKeeper-based cluster manager looks after the state of the cluster itself. —the morning paper (the full paper is here)

Indiana University Uses Docker Datacenter for Production-Ready Orchestration
Founded in 1820, Indiana University has over 115,000 undergraduate and graduate students, 20,000 faculty members and eight campuses located throughout the State of Indiana. The University’s vision is to provide their students with the best possible education experience via a world-class IT team.
For almost a decade the university was building custom scripts and deploying their applications onto VMs running on RHEL 6. A process that involved lots of manual work. In addition to this, their environment was optimized for their legacy Java-based applications.
In order to give their students the best experience possible, the University needed to not only modernize their 150 applications that span across both administrative and student lines and include everything from human resources based applications, course selection, finances and other student-facing applications. They also needed the ability to deploy their applications across their multi-host datacenter environment. They required a production-ready solution. A tool that would enable them to build new process around packaging, deployment, management, and scale for both centralized and de-centralized environments at the same time.
For this, Indiana University turned to the Docker Datacenter (DDC) solution. DDC is our commercial solution that delivers a Containers as a Service platform and includes: Universal Control Continue reading
Introducing Ansible Tower 3
The Best Way To Run Ansible In Your Organization Just Got Better
We’ve been hard at work since the last release of Tower, listening to community feedback and working to create the best possible experience for Tower users. We are pleased to introduce Ansible Tower 3, evolving from Ansible’s simple, powerful and agentless automation and extending that power to your team and organization.
Tower 3 boasts an entirely reworked UI that makes it simpler and easier to use Tower to automate your environments and share your automation. On top of that, we’ve equipped this newest edition of Tower with a host of new features to speed productivity and visibility within your Tower workflows, managing complex deployments and scaling the power of automation.
These features include:
Expanded and Simplified Permissions
In prior releases of Tower, we operated on an implicit permissions system. For a user to be able to see, and run, a job, they needed permissions on not only the project that housed the Playbook, but also the inventory, and the credential used.
Now, with Tower 3, we’ve made things much simpler… if you have a job that you want a user or team to run, just give them Continue reading
Fixing The CCIE Written – A Follow Up
I stirred up quite the hornet’s nest last week, didn’t I? I posted about how I thought the CCIE Routing and Switching Written Exam needed to be fixed. I got 75 favorites on Twitter and 40 retweets of my post, not to mention the countless people that shared it on a variety of forums and other sites. Since I was at Cisco Live, I had a lot of people coming up to me saying that they agreed with my views. I also had quite a few people that weren’t thrilled with my perspective. Thankfully, I had the chance to sit down with Yusuf Bhaiji, head of the CCIE program, and chat about things. I wanted to share some thoughts here.
Clarity Of Purpose
One of the biggest complaints that I’ve heard is that I was being “malicious” in my post with regards to the CCIE. I was also told that it was a case of “sour grapes” and even that the exam was as hard as it was on purpose because the CCIE is supposed to be hard. Mostly, I felt upset that people were under the impression that my post was designed to destroy, harm, or otherwise defame the Continue reading
