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.

Two new Pluralsight Courses: Heroku & Cloud Computing Fundamentals

Over the past couple of months I have been hard at work on some more Pluralsight courses. I am excited to announce that today I released 2 new courses on Pluralsight! These are both cloud related courses. One course is more DevOps focused and the other is focused more on cloud security. One of the courses is intermediate while the other is for those beginning with cloud. It’s pretty cool to have two courses listed on Pluralsight’s new releases!

Heroku: The Big Picture 
by Steve Buchanan 
The fm

Heroku is a cloud PaaS service that enables companies to speed up the application lifecycle; building, delivering, monitoring, and scaling applications without the headaches of standing up infrastructure to support the application. 

Some of the major topics covered in this Cloud Computing course are:

  • Learn about the components of the Heroku platform and how it works including the architecture, idea to running app, the runtime, Dynos and the various Heroku services.
  • Gain an understanding about the benefits and limitations of the Heroku platform such as pricing, language support, and ecosystem.
  • Insight into the developer and operational experience on Heroku.
  • And you will also see demos on the Heroku Dashboard, Using the Heroku Estimators, and deployment of an application to the Heroku platform.

By the end of this course, you will gain a better understanding of the Heroku platform all up including how to build and operate an application on it.

Some of the major topics covered in this Cloud Computing course are:

  • Identifying the importance and impacts of compliance in the cloud
  • Understanding cloud policies or procedures
  • Recognizing risk management concepts related to cloud services
  • Security concerns, measures, or concepts of cloud operations

This Cloud Computing course will help you prepare for the CompTIA Cloud Essentials+ exam. This course is also useful if you don’t plan to take the CompTIA exam and just need to ramp up on cloud security.

Take this course if you want to learn cloud essentials, what it takes to successfully adopt cloud, the impact of cloud on IT service management, how security, and risks apply to cloud as well as consequences. This course is for someone with some exposure to cloud technologies and a general background in Information Technology at the minimum of a business analyst level.
