Groups are used in Lenses to define Namespaces and Permissions. Authorization rules in Lenses are only determined by the Groups. User and Service accounts must belong to at least one Group so they can be used. There are no default groups in Lenses.
Namespaces are used to provide multi-tenancy. They are a way to divide cluster data between multiple users or teams, via topic names and wildcards. Each namespace has permissions that can be apply to compose access for the group.
