Overview

Over the last few years CI/CD (Continuous Integration/Continuous Deployment) thanks to new technologies has become a lot easier. It should no longer be a major thorn in the side of developers. Many are moving to cloud platforms which has CI/CD built-in (Azure DevOps for example), others are using Kubernetes which clearly reduces a lot of the complexity around CI/CD. Still at many organizations I see Jenkins or other complex and often homegrown tooling. I certainly recognize this tooling was needed but in 2019 there are better, more streamlined options. Now I get it, our butler Jenkins has served us well, for many years, he has become part of our family. But just like the famous Butler, Alfred from Batman, he has gotten old and likely it is time to look into retirement.

In this article we will discuss and demonstrate how to use Ansible Tower and GitHub for CI/CD.

Overview

Immediately after Solomon Hykes first showed Docker to the public at PyCon in 2013, in his now famous “docker run demo”, IT folk started asking, what does this mean for virtualization? We only spent the previous 10-15 years virtualizing, seemingly everything, so understandably people were slightly apprehensive. Industries had been built and careers established, clearly virtualization would be an important part of the future and not simply replaced, right?

In this article we will aim to understand the value of virtualization in a container-driven world, explore the current virtualization capabilities in Kubernetes and get started with Container Native Virtualization (Kubevirt) using Red Hat’s Kubernetes enterprise distribution, OpenShift.

Overview

Before getting started you might want to read about the birth of the niche cloud in the first part of this two part series.

We have all heard the saying, you cannot teach an old dog new tricks. Yes that is true, but we aren’t thankfully dogs. Learning to do something new of course, requires an open mind-set and a desire for change. Many organizations are getting left out of digital disruption these days because they keep falling back on old outdated ideas, behaviors and habits. Our minds are so full, so occupied and so tired we simply cannot grasp or don’t have the energy for anything new. We spend our time applying what is new to what we know, which is old.

In this article lets reset our minds and look at an approach to build a niche cloud from the ground up. Instead of pealing back the onion we will apply layer after layer until we have the onion itself. Of course I realize there is a lot more and this article is just scratching at the surface, nevertheless it is an approach, a basic rule-set and guideline for getting started.
