Azure Key Vault limits

We are developing authentication service (using identityServer) and we want to sign the JWT token returned to the user with private key stored in Azure Key Vault HSM

Our domain consists of millions of users that expected to call the authentication service once an hour in average (and therefore the key vault)

According to Microsoft docs the key vault service limits is 100 calls per second. See: https://azure.microsoft.com/en-us/documentation/articles/key-vault-service-limits/

Are we using Azure Key Vault as we suppose to do? It seems that the Key Vault transactions volume is very low.

If you look at the pricing page there is a footnote that says -

contact Microsoft for pricing for operation volumes exceeding 50 million operations per month

The alternative is to use Key vault as a key signing service, so you have a key that is signed by the key in key vault, that is rotated amongst your servers. It would be an extra piece of work, but it means that you can have very short lived certificates, which could provide a little additional security.
