HDInsight on AKS is a modern, reliable, secure, and fully managed Platform as a Service (PaaS) that runs on Azure Kubernetes Service (AKS). HDInsight on AKS allows you to deploy popular Open-Source Analytics workloads like Apache Spark™, Apache Flink®️, and Trino without the overhead of managing and monitoring containers.

**Apache Flink Application Mode Cluster**
41
-
Application mode clusters are designed to support dedicated resources for big and long-running jobs. When you have resource-intensive or extensive data processing tasks, you can use the [Application Mode Cluster](https://flink.apache.org/2020/07/14/application-deployment-in-flink-current-state-and-the-new-application-mode/#application-mode). This mode allows you to allocate dedicated resources for specific Apache Flink applications, ensuring that they have the necessary computing power and memory to handle large workloads effectively.

**Private Clusters for HDInsight on AKS**
44
44
With private clusters, and outbound cluster settings you can now control ingress and egress traffic from HDInsight on AKS cluster pools and clusters.
45
45
46
46
1. Use Azure Firewall or Network Security Groups (NSGs) to control the egress traffic, when you opt to use outbound cluster pool with load balancer.
47
47
1. Use Outbound cluster pool with User defined routing to control egress traffic at the subnet level.
48
48
1. Use Private AKS cluster feature - To ensure AKS control plane, or API server has internal IP addresses. The network traffic between AKS Control plane / API server and HDInsight on AKS node pools (clusters) remains on the private network only.
49

1. Avoid creating public IPs for the cluster, use private ingress feature on your clusters.

### Known issues

-**Workload identity limitation:**
58
-
-There is a known [limitation](/azure/aks/workload-identity-overview#limitations) when transitioning to workload identity. This is due to the permission-sensitive nature of FIC operations. Users cannot perform deletion of a cluster by deleting the resource group. Cluster deletion requests must be triggered by the application/user/principal with FIC/delete permissions. In case, the FIC deletion fails, the high-level cluster deletion will also fail.
59
-
-**User Assigned Managed Identities (UAMI)** support is limited – There is a limit of 20 FICs per UAMI. You can only create 20 Federated Credentials on an identity. In HDInsight on AKS cluster, FIC (Federated Identity Credential) and SA are one-to-one mapping and only 20SAs can be created against an MSI. If you want to create more clusters, then provide different MSIs to overcome the limitation.
