| Intended users | The documentation recommends EKS Capabilities for EKS users seeking a managed experience and self-managed installation for users needing version and configuration control or running other Kubernetes environments. | ASO is aimed at users who want to manage Azure resources with Kubernetes tooling and primitives such as kubectl apply. |
| Purpose | ACK lets users define and manage AWS resources directly from Kubernetes using Kubernetes custom resources. | Azure Service Operator lets users deploy and maintain Azure resources from within a Kubernetes cluster using Kubernetes tooling. |
| Reconciliation | ACK periodically reconciles desired resource state with actual state in AWS and corrects drift. | ASO uses asynchronous reconciliation and does not block while Azure resources are created. |

In their own words
AWS Controllers for Kubernetes
AWS Controllers for Kubernetes (ACK) lets Kubernetes users define AWS resources with Kubernetes custom resources. It periodically compares desired and actual AWS state and corrects drift. Documentation lists 74 service controllers, including S3, RDS, Lambda and DynamoDB. ACK supports declarative, version-controlled infrastructure alongside applications, across AWS accounts and regions. Read-only resources and read-only adoption support migration from other infrastructure-as-code tools. EKS users can install managed EKS Capabilities, where AWS handles controller installation and upgrades with automatic updates, auto-scaling and auto-tuning. Self-managed Helm installation runs on EKS, GKE, AKS, on-premises clusters and local environments, providing version and configuration control. AWS IAM authorizes controller access. Self-managed ACK costs nothing for Helm installation on Kubernetes 1.20+ on any Kubernetes cluster. EKS Capability pricing is hourly, with a base rate per enabled capability plus usage charges for each ACK resource managed.
