Azure Key VaultvsGoogle Secret Manager
A decision guide for teams choosing an operating model—not a feature-count contest. Validate current limits and pricing in the linked product documentation before committing.
01 / Short answer
Choose for the constraint you cannot ignore.
Azure Key Vault: Azure workloads needing provider-native secret, key or certificate controls.
Google Secret Manager: Google Cloud workloads wanting a managed secret store and native identity controls.
02 / Decision matrix
The operating differences.
| Criterion | Azure Key Vault | Google Secret Manager |
|---|---|---|
| Operating model | Azure service for secrets, keys and certificates integrated with Entra identities. | Google Cloud-native versioned secret storage controlled through IAM. |
| Best fit | Azure workloads needing provider-native secret, key or certificate controls. | Google Cloud workloads wanting a managed secret store and native identity controls. |
| Main trade-off | Vault topology, network access and role model need deliberate design. | Project boundaries, replication and access inheritance need review. |
| Pricing basis | Operations, objects and service tier | Secret versions and access operations |
| Portability lens | Most value comes from its own platform integration; price migration explicitly. | Most value comes from its own platform integration; price migration explicitly. |
03 / Selection test
Run a proof of operation, not a polished demo.
The test should include deployment, identity, telemetry, failure recovery and one real policy requirement. A happy-path deployment cannot expose day-two cost.
- 01Trust boundary
Test this with one representative workload and record the operational owner, failure path and exit cost.
- 02Identity integration
Test this with one representative workload and record the operational owner, failure path and exit cost.
- 03Rotation model
Test this with one representative workload and record the operational owner, failure path and exit cost.
- 04Portability
Test this with one representative workload and record the operational owner, failure path and exit cost.
- 05Operational burden
Test this with one representative workload and record the operational owner, failure path and exit cost.
Google Cloud workloads wanting a managed secret store and native identity controls.
Project boundaries, replication and access inheritance need review.
The responsibility boundary is explicit.
Name which system owns identity, deployment, policy, telemetry and recovery. If both appear to own the same decision, simplify.
04 / Due diligence
Verify before signing or migrating.
- Current regional availability, limits and deprecation policy.
- Total cost at expected usage, including data, support and operations.
- Identity, audit-log and private-network requirements.
- Backup, export and exit path for configuration and data.
- Skills required for upgrades, incidents and policy exceptions.
