As the mass migration to containerize software applications continues, Kubernetes has overwhelmingly become the platform to run those applications. Cloud providers like AWS, Google, and Microsoft bundle complex Kubernetes services to make it easier to deploy and scale applications. On-premises data centers and devices let companies manage the costs and security of their Kubernetes clusters themselves. Kubernetes can also be found outside of data centers for edge computing, IOT devices, and 5G networks. Kubernetes is literally everywhere.

The demand for Kubernetes expertise at a premium as the leading platform for large clouds and small on-premises computing. Kubernetes Everywhere steps you through creating your own on-premises, professional-grade Kubernetes cluster. Along the way, you gain the knowledge to master features such as deployment methods, network setup, storage management, node autoscaling, authentication, and pod and cluster security. You learn ways to obtain Kubernetes certifications, find online resources for trying Kubernetes and participate in the Kubernetes project community. While the book points out quick-start ways of using Kubernetes, the main difference from other Kubernetes instructions is its focus on careful planning and understanding at each step in the process. You learn each topic at the point in the process where you would be setting it up in a real Kubernetes cluster.
