To limit the number of TKG (Tanzu Kubernetes Grid) clusters a tenant can provision while allowing other tenants an unlimited number of clusters, you should specify a quota in the Organization settings. This approach allows the cloud provider to set specific resource limitations for individual tenants, ensuring that one tenant cannot exceed their designated limit while others can continue to provision an unlimited number of clusters. Configuring quotas and limitations in the Organization settings is the most straightforward method to manage tenant-specific restrictions on resources.
