-Aggregated APIs are subordinate API servers that sit behind the primary API server, which acts as a proxy. This arrangement is called [API Aggregation](/docs/concepts/extend-kubernetes/api-extension/apiserver-aggregation/) (AA). To users, it simply appears that the Kubernetes API is extended.

 CRDs allow users to create new types of resources without adding another API server. You do not need to understand API Aggregation to use CRDs.
