I was fortunate to be introduced to Kubernetes (and containers) fairly early in their lifetime. Whilst leading the DevOps practice for a boutique consultancy, I saw the potential for containers to bring huge benefits to a lot of our clients. That excitement and interest led me to take a role at Docker Inc., where I witnessed firsthand some of the incredible innovations taking shape in the burgeoning cloud native world.

Kubernetes began to pick up steam and I moved to Heptio (founded by the creators of the project at Google, later acquired by VMware) to focus on helping clients and the community learn and deploy it successfully. Because of this experience, I sometimes forget that many folks are just now exploring and adopting these technologies and their capabilities for the first time.

Recently I was working alongside a client and demonstrating the capability of Kubernetes to automatically provision a cloud load balancer, register the appropriate DNS name, and attach the relevant TLS certificate for their application to be publicly accessible. Thats SO cool! was their response to our success, and captures perfectly the feelings I experienced when first discovering and learning Kubernetes. Unfortunately, as with almost any advanced technology, its not all sunshine and roses.

One of the criticisms oft-leveled at Kubernetes is that its complicated, which (in my mind, at least!) seems to carry a negative connotation. I disagree, and prefer to describe it as necessarily complex. Kubernetes has many moving parts, all working together to construct an application platform that can provide resiliency, efficiency, and extensibility at the highest scale. It encapsulates shared knowledge and saves us all the time and effort of reimplementing a lot of the common functionality that it provides.

However, as a new user it can be daunting to choose where to dive in with such a vast array of functionality, not to mention the plethora of associated tools that exist in the wider cloud native ecosystem. For this reason, one of my favorite things about Cloud Native DevOps with Kubernetes is that the authors have assumed no prior knowledge. This really is a volume I would have loved in this space when I was starting out, awestruck and bewildered at the vast possibilities in front of me!

Once you flip the page, youll begin by understanding the historical and cultural context behind DevOps and Kubernetes before being introduced to practical examples that are easy to follow and directly relevant to implementing these technologies in real-world scenarios. Therefore, whereas some titles are more reference-like in their approach, I recommend that you read this book in order.

Justin and John have done a great job crafting a narrative that builds on what has come before. New concepts are deployed in a layered way, allowing you to explore them in greater depth as you progress. Even so, upon completing the book it can absolutely be used as a concise reference to key everyday concepts that youll find yourself turning to over and over again.

Owing to a balanced mix of hands-on examples and pragmatic business advice, I often find myself recommending this book as the one-stop shop to prime both architects and engineers with the knowledge they need to understand the cloud native landscape and start their journey toward deploying a successful Kubernetes application platform.
