How does Google Database Migration Service compare to AWS DMS?

Google DMS is serverless and focused on migrating to Cloud SQL and AlloyDB with minimal configuration. AWS DMS supports a broader range of source and target databases including Oracle, MongoDB, and SAP. Both use CDC for minimal-downtime migrations. Google DMS provides a simpler UX for PostgreSQL-to-PostgreSQL migrations; AWS DMS is more versatile for cross-database-engine migrations.

When should I use Debezium instead of AWS DMS?

Use Debezium when you need database change events in Kafka for downstream consumers beyond a single migration target, when you want open-source without vendor lock-in, or when you need to stream changes to multiple targets simultaneously. Debezium requires Kafka operational expertise but provides more flexibility than DMS for event-driven architectures and real-time analytics pipelines.

Can Fivetran or Airbyte replace AWS DMS for database migration?

Fivetran and Airbyte are optimized for ELT pipelines replicating databases into data warehouses (Snowflake, BigQuery, Redshift) rather than database-to-database migrations. They handle schema drift and incremental loading well. For transactional database-to-database migrations with CDC and minimal downtime cutover, DMS, OCI GoldenGate, or Debezium are more appropriate tools.
