Every technology-focused business needs the right technical and architectural experience to make technical decisions effectively, balancing the trade-offs. Decision-making is the cognitive process of selecting a course of action among several possible alternative options. Technical decision-making is less about the tool to pick and more about the problem to solve. Once the problem space is…
At work, my team owns and maintains a large lab environment for the development and testing of Rubrik Build projects. It was built in a hurry, causing some of our original design principles to be compromised. My team and I have decided to use this no-travel period as an opportunity to redesign and redeploy our…
I have previously written about putting together the conceptual model with logical and physical design; however, I want to dig a little deeper into the conceptual model. The conceptual model categorizes the assessment findings into requirements, constraints, assumptions, and risks: Business requirements are provided by key stakeholders and the goal of every solution is to achieve…
Effective leaders know that problem solving is not “one-size-fits-all”. The action taken depends on the situation and, because the circumstances are changing, better decisions can be by using an adaptive approach. I have previously written about the 75% method that I learned in the military, but there’s another framework that I have consistently used with…
Change management has never been easy for the dev or the ops side of the house. Let’s face it; it’s usually a checklist item and a tool to CYA. However, we are moving to a world where change is a part of the culture and a frequent process. There is no excuse to not improve.…
Value stream mapping (VSM) does exactly that: it is a DevOps framework (“borrowed” from manufacturing) that provides a structured way for cross-functional teams to collectively see where we are today (long release cycles, silos, damage control afterwards, etc.) and where we want to be in the future (short release cycles, infrastructure as code, iterative development,…
At the time of writing, there are 197 days left before vSphere 5.5 is end of life and no longer supported. I am currently in the middle of an architecture project at work and was reminded of the importance of upgrading — not just for the coolest new features, but for the business value in doing…
Before getting too far into the topic, let’s first take a quick look at the difference between mutability and immutability. Mutable Immutable Continually updated, patched, and tuned to meet the ongoing needs of the purpose it serves. State does not change or deviated once constructed. Any changes result in the deployment of a new version…
It is imperative for any file system to be highly scalable, performant, and fault tolerant. Otherwise…why would you even bother to store data there? But realistically, achieving fault tolerance is done through data redundancy. On the flipside, the cost of redundancy is increased storage overhead. There are two possible encoding schemes for fault tolerance: triple…
Part of me feels like it flew by but then I remember the hours spent reviewing all the designs (*ahem* Adam) and then it feels like it took an eternity to get through. Admittedly, Virtual Design Master was probably one of the coolest community driven events in which I have participated. If you are unfamiliar…
