SDx applications have new needs from next-gen IT infrastructure that go beyond old models and architectures. Find out what they and stake your claim in the SDx world.
Kilo is the eleventh major OpenStack release, with enhancements across the board and new features like Ironic for bare metal service provisioning. SMB to large-scale clouds with OpenStack are being deployed in droves with a self-service portal to spin up virtual and now bare metal workloads while automatically provisioning all the requisite compute, storage and networking resources. Yet, network service provisioning remains to be cumbersome, brittle and closed.
OpenStack and Cumulus Linux share a common philosophy, design and operational framework. Compute and storage (with Cinder and Swift) leverage standard infrastructure, so why use black boxes from Cisco and Arista, especially when the systems are merchant silicon reference designs. Cumulus Linux is unencumbered Linux without proprietary APIs and protocols, with the flexibility to run on your platform of choice. Build and runtime operations are identical from bootstrapping infrastructure with PXE or ONIE to lifecycle management with config management and patching. Clouds have become the new frontier not only for orchestration platforms like OpenStack but for tools, processes and organizations. Converged administration with battle-tested automation platforms (such as Puppet, Chef or Ansible) or monitoring (with Nagios or collectd) enable admins to rise to critical tasks such Continue reading
Price cuts are what's keeping hardware switch sales looking strong, Cumulus claims.
I have moved to a new blogging platform! The timing was interesting, since the wordpress installation on which Keeping It Classless has operated for so long is about 5 years old (I operated on an older domain before Keeping It Classless was born).
WOW. Five years is a long time in blog years. I could not have possibly predicted back then what this blog would do for me. In going over these old posts, I saw a very interesting progression of my own skillsets and mentality, and I figured I’d share. Call it a thank you for helping me grow the past 5 years. Please forgive the length of this post, but I wanted to make sure to call out everything of significance.
It’s also been crazy to witness the change in writing style. Early on I was not shy about using idioms, memes, and Borat references in blog posts, and now - while I am still humorous from time to time - I am a little more formal and succinct. Another way of looking at it is that early on, there was very little difference between the way that I wrote and the way that I spoke. Today, there Continue reading
Many years ago, I worked for a manager who had two signs on his desk. The first was a pencil with the words, “Pencil 2.0″ printed above them. The rest of the sign went on to explain how the pencil had undo (the eraser), was renewable (it can be sharpened), etc. The second sign was simpler, just two black words printed across a white background.
Eschew Obfuscation
Being just out of the US Air Force, and not having quite the vocabulary I should have (have I ever told you that reading is the key to having a great vocabulary?), I didn’t really understand the point. Now I do. Okay, to make it more obvious, from the Collins English Dictionary, 8th edition:
eschew: tr to keep clear of or abstain from (something disliked, injurious, etc.); shun; avoid
obfuscation: the act or an instance of making something obscure, dark, or difficult to understand
Now do you see? Avoid using language people can’t understand. Far too often, in the technical world, we use abbreviations, acronyms, and all sorts of cute nonsense to say things. We pepper our language with shorthands and inside jokes (squirrel!). While this sometimes helps communication, Continue reading
