On-premises systems typically authenticate against Microsoft Active Directory or LDAP. Meanwhile, public cloud workloads each use their own IDP: * AWS workloads authenticate with [AWS IAM](https://docs.aws.amazon.com/iam/) * Azure services rely on [Azure Active Directory](https://docs.microsoft.com/azure/active-directory/) * GCP applications leverage [Google Cloud IAM](https://cloud.google.com/iam) As organizations migrate, containerize, or adopt immutable infrastructure across clouds, this fragmentation leads to: * Operational overhead from maintaining multiple integrations * Security risks due to inconsistent credential lifecycles * Developer confusion over which credentials to use ## Vault: Your Unified Secrets Gateway HashiCorp Vault centralizes identity and secret management, providing a single integration point for applications. Instead of coding against each cloud’s API, apps authenticate to Vault. Vault then dynamically issues or retrieves credentials from your existing IDPs: Active Directory, AWS IAM, Azure AD, or Google Cloud IAM. ![The image illustrates why organizations choose Vault, showing connections from AWS, Azure, and GCP to a central Vault, with a building and a person at a computer.](https://kodekloud.com/kk-media/image/upload/v1752878197/notes-assets/images/HashiCorp-Certified-Vault-Associate-Certification-Why-Organizations-Choose-Vault/vault-architecture-aws-azure-gcp.jpg) ### Core Benefits * **Dynamic secrets**: On-demand credentials with configurable TTLs * **Consistent policy enforcement**: Centralized, versioned access controls * **Simplified developer experience**: One API endpoint for all secrets * **Enhanced security posture**: Short-lived credentials reduce blast radius Vault’s dynamic secrets engine issues credentials at runtime and automatically revokes them at expiration, eliminating manual key rotation. ### Advanced Secret Management Features * **Transit Secrets Engine**: Encryption-as-a-service for data-in-transit * **Static Secrets Storage**: Secure key/value store for API keys, tokens, certificates * **Leasing & Renewal**: Automatic credential renewal and revocation * **Audit Logging**: Detailed, tamper-proof audit trails ![The image illustrates why organizations choose Vault, showing connections between a building, AWS, Azure, GCP, and a computer, all linked to a central Vault icon.
