We love stories about how Ansible Tower has solved problems and made work easier. Special thanks to Hugh Ma from Flex for sharing his story about Ansible Tower.
Here at Flex, our Ciii Rack Scale Platforms team regularly deploys Openstack and Ceph on large clusters with various SDN platforms. With repeated multi-rack deployment, validation, benchmarking and tear down, automation plays a crucial role in improving the agility of our operations. For a small automation team to support a large group of engineers working across 200+ servers, it is necessary to select the right tools to simplify deployment, test infrastructure installation, debugging, and results collection. This enables the team to focus on reference architecture designs, benchmark logic, and results analysis.
We had originally developed a python-based automation framework for our testing. Some of its tasks included configuring operating system and OpenStack settings through their APIs, launching test workloads, and parsing output. However, with a small team, upkeep of such a large code base and an increasing complexity of test parameters became tedious We started looking at configuration management(CM) tools. We wanted a CM tool that was based on Python but easy for non-developers to use and straight-forward to troubleshoot. After building Continue reading
In the context of the Internet and BGP routing, DFZ – commonly known as Default Free Zone – refers to the collections of all the public IPv4 BGP prefixes without default route on the global Internet. Most of the time, you hear full-route or full-Internet-route terms which are the same with Default Free Zone term. Having all BGP routes, […]

Follow these best practices to avoid security pitfalls with your Internet of Things deployment.
A look at the evolution of a technology that's poised to make big waves in storage.
One of my ExpertExpress engagements focused on networking in a future private cloud that might be built using OpenStack. The customer planned to deploy multiple data centers, and I recommended that they do everything they can to make sure they don’t make them a single failure domain.
Next step: translate that requirement into OpenStack terms.

Before moving on the next post to continue our saga of OpenSwitch Simulations with GNS3, I wanted to take a quick deviation to document a subject that gets a lot of attention these days: P4.
In case you have been missing all the action around P4, the 30,000 feet view is that it’s a language to describe forwarding pipelines (and no, it’s not the same as OpenFlow, that is useful for programming entries in almost-always-pre-defined pipelines). One of the (many) nice things about this is that you can potentially ‘compile’ your pipeline definition into an executable program that provides a functional simulation of a P4-based ASIC. Did I mention the tools for doing all of this are available as open source?
Cloudify also spawns a new open source group: Aria.
