Infrastructure-as-Code: Bootstrap CoreOS with Ignition

The first post in the series went over the design goals and the logical diagram of the Kubernetes environment. This post will include the necessary steps to PXEBOOT a CoreOS node, install the VMware Tools included version of CoreOS and perform an initial configuration of the CoreOS node with Ignition. After determining what the Infrastructure-as-Code project would be working to […]

Infrastructure-as-Code: Project Overview

In an effort to get caught-up with the Cloud Native space, I am embarking on an effort to build a completely dynamic Kubernetes environment entirely through code. To accomplish this, I am using (and learning) several technologies, including: Container OS (CoreOS) for the Kubernetes nodes. Ignition for configuring CoreOS. Ansible for automation and orchestration. Kubernetes VMware NSX for micro-segmention, load […]

VCDX Sample Architecture Design Decisions

In preparing for my recent VCDX Defense, I read a great deal of articles and a few books to better understand how to properly document and justify the design decisions I was making. One book in particular provided valuable insight that has helped me not just with the VCDX certification, but also in becoming a better Infrastructure Architect.

In this blog post, I will cover the approach taken when preparing my VCDX documentation with regards to providing insight and justifications for the design decisions made within my VMware Integrated OpenStack architecture.

VCDX Sample Architecture Table of Contents

During the process of writing the documentation necessary for the VCDX certification, I read several books and a fair number of blog articles. One article in particular that I found helpful was from Derek Seaman’s blog.

In the spirit of paying it forward, I am going to share my own table of contents for others to use as a starting point. No two will be the same and some of the things I included may not be necessary in your own design — you may even feel there are sections that are missing from my own. If nothing else, I hope it can be a starting point for you in the journey towards earning the VCDX certification.

Post-Defense VCDX Thoughts

“Nothing in the world is worth having or worth doing unless it means effort, pain, difficulty… I have never in my life envied a human being who led an easy life. I have envied a great many people who led difficult lives and led them well.” -Theodore Roosevelt That quote from Theodore Roosevelt sums up rather well the VCDX certification. […]
