What "Kubernetes" does and how? After working in the technology and consulting ecosystem for the last 10 years, I am a huge supporter of simplification. While I understood the whole concept of Containerization and automating the deployment, I wanted to explain the bunch of newly recruited Technology Consultants in our team that how actually it's used and deployed. So, the logical topics to be explained with examples were: The Background of it? Why we needed this system in first place? How Kubernetes Operates? The Nuts and Bolts of the system. How it is deployed? Best Practices If these things are clear with examples then we can operate with confidence and manage the project well. So, here it is. All our discussions are formulated in a book to help you people to take your respective agenda ahead in your current role with conviction. The book has been written in a simple, easy to comprehend language and can be used by Non-Programmers, Project Managers, Business Consultants or any other persons with an interest in Kubernetes. So, move ahead with your Continuous Development journey with this new book and as I mentioned earlier: let's simplify the discussions around!

This hands-on guidebook to the inner workings of containers peels back the layers to provide a deep understanding of what a container is, how containerization changes the way programs run, and how Kubernetes provides computing, networking, and storage. Containers ensure that software runs reliably no matter where it’s deployed, and Kubernetes lets you manage all of your containers from a single control plane. In this comprehensive tour of the open-source platform, each chapter includes a set of example scripts with just enough automation to start your container exploration with ease. Beginning with an overview of modern architecture and the benefits of orchestration, you'll quickly learn how to create containers; how to deploy, administer and debug Kubernetes clusters all the way down to the OS; and how container networking works at the packet level across multiple nodes in a cluster.
