Limitations on Azure
This section lists some resource limits that CML and Azure impose on workloads running in ML workspaces.
- You have to request access from Microsoft to set up an Azure NetApp Files account. You are prompted to do this when you first try to set the account up, and it may take some time for Microsoft to grant access.
There is no ability to grant or revoke remote access (via Kubeconfig) to specific users. Users with the MLAdmin role in the environment can download a Kubeconfig file. The Kubeconfig file will continue to allow access even if the MLAdmin role is later revoked.
Support is limited to regions that provide AKS. Also, customers should check availability of Azure NetApp Files and GPU instance types in their intended region.
- Data is not encrypted in transit to Azure NetApp Files or other NFS systems, so make sure to implement policies to ensure security at the network level.
Each ML workspace requires a separate subnet. For more information on this issue, see Use kubenet networking with your own IP address ranges in Azure Kubernetes Service (AKS).
- When you provision an Azure Kubernetes (AKS) cluster, a Standard load balancer is provisioned by default. The Standard load balancer always provisions a public IP for egress traffic, communication with the Kubernetes control plane, and backwards compatibility. Cloudera software does not use this public IP directly, or expose anything on it. It is currently not possible to provide networking rules or other mechanisms to enable public AKS to work.
