Azure Key Vault review

Azure Key Vault is the obvious pick for Azure workloads because it combines secrets, keys and certificates in one service with transaction-based pricing. Secrets operations cost $0.03 per 10,000 transactions on both the Standard and Premium tiers, so a small application reading a few secrets costs very little. Vaults hold cryptographic keys, secrets, certificates and storage account keys, and Managed HSM pools are available when you need HSM-backed keys. Certificate renewals cost $3 per renewal request, and managed storage account key rotation is free while in preview. Advanced key types such as RSA 3,072-bit, RSA 4,096-bit and ECC keys cost $0.15 per 10,000 transactions. It scores lower on ease of use than the developer-focused tools because it is built around Azure subscriptions and identities, and it lacks the shared environment and local CLI workflow of Doppler or Infisical.
