Good day fbinotto - I have not seem the limitation of "Storage Accounts with less than 4.5M transactions per month will not benefit from the new plan and may continue in the per-transaction plan." documented anywhere. Can you provide some references ?
From all online articles it indices
- First 73Mil transactions per month are covered under the $10/month/storage account OR [ $0.0134 per storage account/hour] https://learn.microsoft.com/en-us/azure/storage/common/azure-defender-storage-configure?tabs=enable-subscription#availability
- Anything exceeding 73M will be charged $0.1492 for every 1 million transactions that exceed the threshold
At a basic level, the expectation is once you are within the 73M you are covered at the $10 rate per SA, but the caveat you've mentioned implies you can be 'opted' out from that rate.
Please clarify
