Cost assessment
Note
Azure Front Door Standard and Premium has a lower total cost of ownership than Azure Front Door (classic). If you have a request heavy workload, it's recommended to estimate the impact of the request meter of the new tiers. If you have multiple instance of Azure Front Door, it's recommended to estimate the impact of the base fee of the new tiers.
The following are general guidance for getting the right metrics to estimate the cost of the new tiers.
Pull the invoice for the Azure Front Door (classic) profile to get the monthly charges.
Compute the Azure Front Door Standard/Premium pricing using the following table:
Azure Front Door Standard/Premium meter How to calculate from Azure Front Door (classic) metrics Base fee - If you need managed WAF rules, bot protection, or Private Link: $330/month
- If you only need custom WAF rules: $35/monthRequests For Standard:
1. Go to your Azure Front Door (classic) profile, select Metrics from under Monitor in the left side menu pane.
2. Select the Request Count from the Metrics drop-down menu.
3. To view regional metrics, you can apply a split to the data by selecting Client Country or Client Region.
4. If you select Client Country, you need to map them to the corresponding Azure Front Door pricing zone.
For Premium:
You can look at the Request Count and the WAF Request Count metric in the Azure Front Door (classic) profile.
Egress from Azure Front Door edge to client You can obtain this data from your Azure Front Door (classic) invoice or from the Billable Response Size metric in the Azure Front Door (classic) profile. To get a more accurate estimation, apply split by Client Count or Client Region.
Ingress from Azure Front Door edge to origin You can obtain this data from your Azure Front Door (classic) invoice. Refer to the quantities for Data transfer from client to edge location as an estimation. Go to the pricing calculator.
Select the appropriate Azure Front Door tier and zone.
Calculate the total cost for the Azure Front Door Standard/Premium profile from the metrics you obtained in the previous step.
Example scenarios
Azure Front Door Standard/Premium cost less than Azure Front Door (classic) in the first three scenarios. However, in scenario 4 and 5 there are situations where Azure Front Door Standard/Premium can incur higher charges than Azure Front Door (classic). In these scenarios, you can use the cost assessment to estimate the cost of the new tiers.
