At $DAYJOB, we used to have a few internal use Azure Functions (which we’ve migrated to AWS Lambda). My favourite Azure weirdness was a warning message that said some Blob Storage-related thing was about to expire. We hadn’t set up any Blob Storage, the Azure Functions .NET deployment thing we used did. And apparently, there was an encryption key or something with an expiry of 1 year. It seems that Microsoft did not expect code to just work and not need to be redeployed for that long.
