Ensure zone redundancy is enabled in supported regions

Impact:  High Category:  High Availability

APRL GUID:  84636c6c-b317-4722-b603-7b1ffc16384b

Description:

When using the Azure portal, zone redundancy is automatically enabled. However, some Infrastructure as Code (IaC) tools may default this to false. To ensure replication of metadata and events across data centers in an availability zone, always verify that zone redundancy is enabled.

Potential Benefits:

Enhanced fault tolerance for Event Hub

Enable auto-inflate on Event Hub Standard tier

Impact:  High Category:  Scalability

APRL GUID:  fbfef3df-04a5-41b2-a8fd-b8541eb04956

Description:

Enable auto-inflate on Event Hub Standard tier namespaces to automatically scale up throughput units (TUs), meeting usage needs and preventing data ingress or egress throttle scenarios by adjusting to allowed rates.

Potential Benefits:

Prevents throttling by autoscaling TUs
