GKE Cluster in nutshell
I am keeping this short and crisp about GKE. This diagram is self-explanatory and the branching justifies how we need to think when cluster comes into play. Each cluster touches so many aspects of platform. Every branch in this picture is a skillset independently. However whenever you want to take the first step and make things simpler please follow these pointers.
I am not trying to elaborate the diagram further. Please go through it once and then discuss.
