 There are two APIs which can create AKS clusters and it's important to understand the differences.
 
-**ManagedCluster** - is the original API to provision AKS clusters introduced with the [0.4.4 release](https://github.com/kubernetes-sigs/cluster-api-provider-azure/releases/tag/v0.4.4).  This more closely matches the CAPI style for YAML code for other providers. The original code was based on directly using the Azure Go SDK, but in the [1.11.0 release](https://github.com/kubernetes-sigs/cluster-api-provider-azure/releases/tag/v1.11.0) was switched to utilize Azure Service Operator (ASO) as a dependency for provisioning.  This supports the preview API, but does not natively support all AKS features available.  This API will eventually be deprecated, [see the roadmap for more information](../roadmap.md).

 **ASOManagedCluster** - was created in the [1.15 release of CAPZ](https://github.com/kubernetes-sigs/cluster-api-provider-azure/releases/tag/v1.15.0) and creates a CAPI-compliant wrapper around the existing ASO definitions for AKS clusters.  It has 100% API coverage for the preview and current AKS APIs via the ASO AKS CRDs.  This is the long-term plan to support provisioning AKS clusters using CAPZ.
