Thank you, M.Khalid for your nice words! We hope you like the book.
The motivation to write a full book about this topic is mainly coming from the authors' experience and learned lessons (hard lessons). Murat and I went through good and bad experiences dealing with Kubernetes in production over the past few years, so we found that a book about this topic will save a lot of time for others who are starting their production journey with Kubernetes.
We have to admit that Kubernetes is like a monster when you use it for your production workloads, starting from cost management, security, resources management, updateability, disaster recovery, and high availability and uptime. Each of these areas has its own challenges with k8s, and our book provides a guide through these areas and is equipped with best practices hands-on and design ideas that are coming from our world-class engineering.
