Database Migration & CDC across clouds
Managed change-data-capture and migration services - DMS, Datastream, GoldenGate - that copy a database somewhere else and keep it in step.
3 verified modules - all static-validated and publish-checked; live-test pending.
Compare by provider
| Provider | Module | Verification |
|---|---|---|
| AWS | A Migration that Is Not in Clear Text | static-validated |
| Google Cloud | A CDC Stream to BigQuery that Starts, Privately, with a Secret | static-validated |
| Oracle Cloud | A GoldenGate Deployment that Is Private, Backed Up and Patched | static-validated |
How to choose
Compare the source engines each supports and whether it reaches them privately, then what happens at the start (a backfill of history, or changes from now on) and at the end (does destroying the task or stream cancel in-flight work). The credential handling differs: some take a secret reference, some want the password in the definition.
When not to use
Replication is not a backup. It copies the deletion as faithfully as the insert; the thing that survives a mistake at the source is a snapshot, not a replica.
