You can deploy a Kubernetes cluster on a local machine, cloud, on-prem datacenter, or choose a managed Kubernetes cluster. There are also custom solutions across a wide range of cloud providers, or bare metal environments.
If you're learning Kubernetes, use the tools supported by the Kubernetes community, or tools in the ecosystem to set up a Kubernetes cluster on a local machine.
When evaluating a solution for a production environment, consider which aspects of operating a Kubernetes cluster (or _abstractions_) you want to manage yourself or offload to a provider.
