Opinions DevOps Site Reliability Engineering
I've watched the community struggle on and off with job titles for those working in the DevOps market. DevOps is and always will be simply a set of philosophies, beyond that are three major systems-type fields I see companies using DevOps in: Operations, Platform Engineering, and Release Management.Read More →
Workshops Infrastructure DevOps Terraform
Terraform is fundamentally operated off of these things called “state files”. State files literally are the single source of truth, as far as Terraform is concerned, in regard to your infrastructure. They’re formatted in regular JSON but carry a lot of metadata that helps Terraform plan and predict what will happen with your infrastructure.
All infrastructure orchestrators have to work off of some sort of state. Interpreting live infrastructure state is complicated and sluggish at scale so many of them resort to some sort of centrally hosted file system that indicates this state to them. CloudFormation actually does much of the same thing with CloudFormation templates in S3 Buckets, you just see less of it exposed to you.
What Terraform really enables is an organization of infrastructure that can be reused, version controlled, and browsed by anyone in the organization. Nobody goes to the S3 bucket and views the Terraform state file, rather, they view the code that generated that state file hence it’s important not to make manual modifications to infrastructure once an orchestrator has run.Read More →

I recently posted on Facebook that I was ditching Facebook and all of the apps dependent on it. While Spotify isn't inherently dependent on it, I also wanted the opportunity to use Google Music for some of my favorite podcasts. Thus, I made the decision that Spotify was going down too. Migrating from Spotify to Google Play Music is already kind of a difficult task. I've had years of being on Spotify, to the point where I have 850 tracks on playlists and my library. I wanted a way to move my playlists I've built over the years over to Google Music. I found a service called [Soundiiz](soundiiz.com) that performs some needed functions. First, it matches Spotify tracks to Google Play tracks and copies your playlist over. Unfortunately, I found that this only worked for playlists and not my music library. Thus, I took things into my own hands.Read More →
If you haven’t heard, last Wednesday it was revealed that Trustico, a large reseller of TLS certificates, violated customer trust by emailing another reseller 23,000 of their customer private keys. That’s really the gist of what they did, what these articles don’t really cover is the underlying reasons why this is directly bad and why what it means is even worse.Read More →
Opinions DevOps Enterprise Site Reliability Engineering Scrum
At start ups we have the luxury of starting from the ground up. Philosophical and cultural revolutions are always easier to consider when simply nothing exists. This is a common complaint of large enterprises when they examine DevOps, SRE, or Production Engineering for their own organizations. Subsequently they end up morphing the core beliefs of those philosophies to fit their existing culture. While this can be done it really results in a lot of confusion and frustration especially at the ground level where, in the aforementioned disciplines, most of the work and decision making takes place. The question remains what does a properly scaled Enterprise grade version of DevOps looks like?Read More →
