Now that cloud providers are offering a managed Kubernetes service it sounds like setting up a new Kubernetes cluster and start deploying applications to, should be easy...but reality is more brutal than that. Even though Kubernetes Service can be offered as a partially managed offering it doesn't mean that cloud provider takes responsibility for everything. It's extremely important to be aware of what you will be responsible for in terms of operating, securing and maintaining managed Kubernetes clusters - and how these changes will affect the rest of your organization. In this session we'll take a look at what you should consider and include in the planning and designing phase (Day Zero) BEFORE going all-in with managed Kubernetes Service. By looking at some real-life examples we'll see what the consequences may be if some of the areas are not planned for or are down-prioritized.
