New ebook – Azure Arc enabled Kubernetes for Multicloud on O’Reilly

After 6 books with many authors from Packt, APress, & Sams/Pearson I finally had the chance to author a book with O’Reilly. This is an ebook so it can be found and read on the O’Reilly online platform.

It is a great platform that I use personally for my own learning. On their platform, you can find ebooks, books across many publishers (most of my books are on there), video training, and even live training.

This book brings together 4 exciting technologies/topics including Azure, Kubernetes, GitOps, and multi-cloud. The book is shorter than my typical books since it is an ebook. It is only 35 pages and is designed for fast & easy consumption to get an overview of the technology and get an early start.

In this book, we take a journey into one of Microsoft’s newest cloud services Azure Arc enabled Kubernetes (Arc K8s). We explore what Azure Arc K8s is, how it extends the Azure control plane to Kubernetes clusters to manage, secure, and govern them, as well as how GitOps sits are the core of application deployment to Kubernetes clusters and a driver of consistent configuration management for Kubernetes clusters.

Azure Arc is a Microsoft product that promises to extend the Azure control plane for Kubernetes across multiple clouds and on-premises, but how does it do this? In this ebook we will dissect Azure Arc K8s and how it becomes a secret weapon for managing Kubernetes clusters across on-premises, multiple clouds, and regardless of your own rolled Kubernetes clusters or managed services based Kubernetes clusters such as GKE, EKS, etc. I also want to give a shout-out to Michael Levan for reviewing this ebook!

Key Areas from the ebook include:

-Understand the new management challenges that multicloud brings
-Learn how Azure Arc drives consistent governance, security, and management across multicloud
-Gain valuable insights into Microsoft’s Azure ARM control plane for Kubernetes
-Learn how Azure Arc manages Kubernetes clusters across on-premises and multiple cloud deployments
-Explore the GitOps technology pattern and operating model for cloud native applications and Kubernetes
-Use Azure Arc-enabled Kubernetes and GitOps to deploy configurations and applications to Kubernetes clusters

CloudSkills.fm Podcast: Cloud Native, Azure Arc, DevOps, GitOps, Kubernetes, and Azure

Recently I had the honor to be a guest on my friend and fellow Microsoft MVP Mike Pfeiffer’s Cloudskills.fm podcast again! This was episode is “106: Steve Buchanan on Cloud Native, DevOps, GitOps, Kubernetes, and Azure“. I was excited to be a guest again on the CloudSkills podcast and catch up with Mike.

On this new episode, we had a chance to talk about a variety of topics like leveling up your career, what I have been up to, diversity and inclusion in the tech, of course Azure, Azure Arc, DevOps, Kubernetes, GitOps, we even touched on SAP on Azure, among other insights.

You can listen to the podcast episode 106 right here on my blog:

Or you can listen to episode #106 here: https://cloudskills.fm/episodes/106.

Back in 2019 I was a guest on the Cloudskills.fm podcast on episode # 15. The past episode was a lot of fun with more of a focus on your career in the world of IT. If you want to check that out here.

Speaking at Omaha Azure User Group

Today I will be speaking at the Omaha Azure User Group. I will be speaking on Azure Arc enabled Kubernetes and GitOps.

I am really looking forward to this user group meeting! I will be speaking on & showing real-time the power of using Microsoft Azure Arc enabled Kubernetes and GitOps, deploying a Container app to a Google Kubernetes Engine (GKE) cluster on the Google Cloud Platform (GCP). More info on my session:

Session title: Push Code, Not Containers with Azure Arc enabled Kubernetes and GitOps

Session details: Use Azure Arc enabled Kubernetes to manage Kubernetes clusters across Google Cloud Platform and Azure without running a single Kubectl command! In this session, Steve Buchanan will take you into the world of GitOps. He will show you how to deploy applications and configuration to GKE clusters and AKS clusters from a GitHub repository. Explore how we can use this new operating model for Kubernetes and cloud-native apps to declaratively describe and ensure the state of our applications and Kubernetes environments.

GitOps: The Big Picture

There is another wave coming. This wave is GitOps. GitOps is a technology pattern and operational framework. It is often used for Kubernetes however is really for cloud-native applications in general. Being that a large amount of cloud-native applications these days are designed and built to run on Kubernetes it is no surprise that GitOps is commonly adopted in Kubernetes environments. If you are running Kubernetes or looking at it chances are you may have heard of GitOps. This is how I define GitOps:

GitOps is an operating model pattern for cloud native applications storing application & declarative infrastructure code in Git as the source of truth used for automated continuous delivery.”  

Well, that sums up with GitOps is but it still is a mouthful and can take a bit to wrap ones head around it. In a nutshell GitOps is shifting everything to code, storing everything in Git, making Git the source of truth, and using an operator deploy what is described in Git in your environment including the application and the configuration. With GitOps you describe the desired state of your entire system and GitOps makes it so. It simplifies operations and makes the experience for developers much better allowing them to work out of a tool they are familiar with (Git). Here is a basic sample diagram to give you a visual idea about what GitOps is and how it works:

So in the case of Kubernetes you would have your app code in Git, your container images in Git, and your Kubernetes manifest files. Now there is more to it and how it works but we will not get into all of that in this blog post. This is a good Segway to purpose of this blog post.

The purpose of this blog post is that I just dropped my 7th Pluralsight course GitOps: The Big Picture! This was a fun course to build as I am passionate about and like working with Containers, Kubernetes, and cloud.

A quick shoutout to both Fellow Microsoft MVP/Pluralsight Author Tim Warner and Jason Alba for amplifying my new course!

This course teaches the fundamentals of GitOps, the need for GitOps, GitOps architecture, GitOps workflow, GitOps principles, practices, & tooling such as Flux, Argo CD, AND Jenkins X. Also in this course, GitOps: The Big Picture, you’ll learn what it takes to adopt GitOps. First, you’ll explore what GitOps is and its benefits. Next, you’ll discover GitOps Tooling NS Architecture. Finally, you’ll learn how to use GitOps Workflows. When you’re finished with this course, you’ll have the skills & knowledge of the GitOps framework needed to take the next steps with GitOps.

In the course I give a couple of demos so you can see GitOps in action. The first demo is on “deploying an application using Argo CD” and the second demo is on “GitOps in Action with Azure Arc Enabled Kubernetes using Flux”. Another interesting fact about GitOps is we are starting to see the major cloud providers bring GitOps into their offerings such as Azure Arc and or couple GitOps with their services like with GCP GKE as well as create content on using GitOps with their managed Kubernetes services like with AWS EKS.

GitOps is going to continue to grow right along with the continued growth of Containers, Kubernetes, and Cloud. I am all in and you will see blogs, books, courses, speaking at events, and more from me around GitOps as I continue on my personal journey with it.
