Azure Key Vault — Enterprise Secrets Management
Master Azure Key Vault for secrets, keys, and certificates, with managed identities for zero-credential access between services.
In the AWS module, we covered Secrets Manager and the problem of getting credentials out of .env files. Azure Key Vault solves the same problem but goes further. It does not just store secrets — it stores cryptographic keys and SSL certificates too, making it a one-stop shop for everything your application needs to keep secure.
But the real killer feature is not Key Vault itself. It is managed identities — Azure's mechanism that lets your services authenticate to Key Vault without any credentials at all. No connection strings. No API keys. No tokens. Your Azure Function just... asks Key Vault for a secret, and Key Vault verifies the request through Azure's identity system.
Zero credentials to manage means zero credentials to leak.
