azure-hdinsight-migration-esp-to-non-esp

Migrate HDInsight ESP clusters to non-ESP by provisioning a parallel cluster, enforcing VNet isolation, and using Managed Identity for storage access to maintain your security posture. This approach replaces ESP with Azure-native controls like RBAC and Azure Policy.

The best way to secure non-ESP HDInsight clusters is by implementing private endpoints to remove public exposure and applying per-cluster RBAC/ABAC for data-plane access. You can enforce policy guardrails using Azure Policy and Log Analytics.

Yes, you can use Azure Purview for data lineage and Sentinel for security auditing in your non-ESP HDInsight environment. These services integrate with Log Analytics to provide comprehensive governance and monitoring during and after migration.

Avoid key rotation during HDInsight migration by using Managed Identity for storage and key vault integration. This MSI-based access method securely authenticates your non-ESP clusters to Azure Data Lake Storage without managing credentials manually.

To decommission HDInsight ESP clusters safely, first provision a parallel non-ESP cluster, migrate workloads with private networking, verify data lineage through Purview, and then decommission the ESP cluster. This sequencing ensures no workload disruption.
