Is there any point in using Azure Key Vault over App Configuration?
Yes, yes, I know - they are complimentary, key vault for secrets, app config for... well, app config.
But, considering they are both encrypted, basically for someone to see either a secret or a config value they'd have to have access to your azure portal (this is a low-level bad guy scenario).
The ONLY difference I see is that you can control permissions differently between the vault and config but apart from that if someone unauthorized has access to your portal you've got bigger problems.
So - why? and please only good and real arguments no "because you should" or "because person X said so", what benefits would I reap with key vault that I don't have with app config?
I appreciate your question. I'd re-phrase it to this:
Q) How are are Key Vault and App Configuration designed differently supporting different purposes? And where can I find a clear comparison table of features and benefits?
I also appreciate your aside:
Here is what I found to understand benefits as a contrast:
Article 1: What is Azure App Configuration?
Article 2 : Key management with Key Vault
Article 3: Azure Key Vault recovery management with soft delete and purge protection
