Microsoft Azure Key Vault

Azure Key Vault provides a managed place within Microsoft's cloud infrastructure to store application secrets, cryptographic keys, and certificates. Rather than embedding a database password or other sensitive value directly in application code, a team can keep it in a vault and control access through Azure identities and permissions. Centralized management also supports automated access and certificate-related workflows. Developers, DevOps teams, and IT professionals use it to manage sensitive material across Azure applications and services.

Its purpose differs from general cloud file storage: the focus is controlled access to small but important security assets and operations involving cryptographic keys. It suits organizations seeking a shared approach to secret management, although permissions and application configuration still need careful design.
