DevOps in a Box

My long time fantasy has been to demonstrate an entire CI/CD pipeline with continuous operations of applications to discuss behavior driven operations and testing as monitors.

The call for this happened over and over at DevOpsDays to answer: how does one learn DevOps, practice site reliability engineering, or have a full application lifecycle environment?

So let’s create a minimal viable product BTD scenario of my DevOps Automation system, extend it to prefix Governance and suffix Management, and then drive maturity to illustrate and discuss best practices. I’ve been discussing this with my Nutanix colleagues @mjasted and @andytschmid for a while, so here is the outline and plan of action!

SSH Key Authentication Overview

For those of you new to automation, Linux, and SSH keypairs: Calm Marketplace blueprints leverage all of these with cloud-init to enable security best-practices, but it can be overwhelming on first exposure to handle every link in the chain to launch your first blueprint. a blog series recap!

From September 23, 2015 to May 26, 2016, I took hiatus from my personal blog to explore, explain, and write a number of DevOps articles for my employer on the blog. Nutanix acquired and I am still part of the Nutanix Calm team, but I’m re-posting these articles on my personal blog since the originals are no longer directly accessible. I am also enhancing them to clarify language, add learnings, and append significant developments as postscripts.

The DevOps Maturity Diagram

The opening of my first DevOps article started with:

Let me share what I’ve learned on my journey to DevOps: it is a culturally rendered term and it has a different meaning for everyone.

In that article, I go on to define DevOps and explain the term. Let me share my experience to easily chart the journey of progressive stages to DevOps maturity.

Ten Steps from Pets to Cattle

Why do we need DevOps when IT and Operations succeed in their responsibility for security and uptime, using administrative tools to maintain, backup, and restore those systems? Because the operations domain must be documented, democratized, and distributed to achieve agility before Operations returns to become a force multiplier instead of a keep the lights on organization. Let me demonstrate that traditional values for long lived infrastructure and their retroactive justification do not apply when progressing to a DevOps mindset.

Reconciling Configuration Management and Immutable Infrastructure

Configuration Management in the DevOps World

Declarative Operating Systems

A new breed of operating systems adopt declarative configuration management for an interesting hybrid! OS maintenance of long-lived servers remains a challenge for our “mutable” infrastructure.

Infrastructure as Code and Calm Blueprints

Why is DevOps So Hard?

DevOps Demystified

For a term that is not even six years old, DevOps remains a mysterious pursuit for many software engineering organizations. Let me define DevOps to help you understand and chart your own journey. Hint: it is a cultural term!

I Dream of DevOps, but What is DevOps?

Artifact Repositories

The past: desktop builds uploaded to the FTP server; the present: global artifact delivery networks. Release management and artifact repositories are they way we deliver software and infrastructure today.

Database Change Management

Database configuration management tools allow us version the database and treat it like code! We want DevOps, not mysterious, hidden, hand crafted DBA ops whenever possible. Another flashback to 1998.

HTML Slide Show Survey

PowerPoint and other proprietary slide-ware, bah! We already have a universal, open system for communication called the web, so let’s explore web presentation applications.

Building the LAMP stack with Phing

A flashback to 2007 with a tangible artifact in my journey to infrastructure as code: building the LAMP stack with Phing.

Container Infrastructure Strategy

In these early years of containers, “heavy containers” represent a typical approach which resembles virtual machines, includes the operating system user land, and desires configuration management. Does this starting point represent the opposite of container promise and the journey to immutable infrastructure?

DevOps BTD Pattern for Continuous Deployment

What happens when you find the same macro and micro pattern in your automation diagram? You reinforce your goals to improve code flow and service design on the way to test driven development!

Today's DevOps Automation Diagram

#shipit and #failfast: I want to share and discuss the DevOps Automation Diagram for continuous deployment. Via open source and this blog, we can elevate the state of our software engineering and service design!

A DevOps Automation State Diagram

Wonderful accomplishments kicked-off my Infrastructure as Code project. One needs to start with a map of the world before deciding where to focus their efforts. It’s even better when you can optimize and render the new map in real-time!

Time for a new development project!

What does one do when laid off? You need to scratch that itch and address the things that are in the back of your head and occasionally keep you awake at night. Technical dreams and technical debt follow as I start my Infrastructure as Code blog.
