What is Google Database Migration Service
Google Cloud Database Migration Service is a managed service for migrating databases into Google Cloud, commonly to Cloud SQL, AlloyDB, and other supported targets. It supports lift-and-shift and continuous replication patterns to reduce downtime during cutovers. The service is typically used by cloud architects, database administrators, and platform teams moving workloads from on-premises or other cloud environments into Google Cloud. It integrates with Google Cloud networking, IAM, and monitoring to run migrations as a cloud-managed workflow.
Managed migration orchestration
The service provides a managed workflow for assessment, connectivity setup, migration job execution, and monitoring. This reduces the need to run and maintain separate migration servers or custom scripts for common database moves. It fits organizations that prefer cloud-native operations and centralized control in the Google Cloud console. It also supports ongoing replication for cutover planning rather than only one-time bulk transfers.
Supports low-downtime cutovers
Database Migration Service supports continuous replication for supported engines, enabling near-real-time synchronization before switching applications to the new target. This helps teams plan cutovers with shorter maintenance windows compared with offline export/import approaches. It is useful for production migrations where downtime constraints matter. Monitoring and job status reporting help track replication lag and migration progress.
Integrates with Google Cloud controls
The product uses Google Cloud IAM, VPC networking, and related security controls for access and connectivity. This can simplify governance for teams already standardized on Google Cloud policies and audit practices. It also aligns with Google Cloud logging/monitoring for operational visibility. These integrations reduce the number of third-party components required for database moves into Google Cloud.
Google Cloud–centric targets
The service primarily targets migrations into Google Cloud database services, which can limit usefulness for multi-cloud destination scenarios. Organizations needing frequent migrations between non-Google environments may require additional tools or processes. This can increase overall integration effort when the destination is not a Google-managed database. It is less aligned with vendor-neutral migration programs.
Engine and feature constraints
Supported source/target engines and specific migration modes vary, and not all database features map cleanly to managed targets. Complex workloads (e.g., heavy use of proprietary features, extensions, or unusual data types) may require manual remediation and testing. Schema conversion and application refactoring may still be necessary depending on the source and target combination. Teams should validate compatibility and limitations for their exact versions and features.
Not phone data recovery software
Despite the category list provided, this product does not address mobile device data recovery use cases. It is designed for database migration and replication, not recovering deleted phone files or extracting data from mobile backups. Including it in phone data recovery evaluations would create a mismatch in requirements and capabilities. Buyers should separate database migration needs from end-user device recovery tools.
Plan & Pricing
Pricing model: Pay-as-you-go Free tier/notes:
- Homogeneous (native) migrations to Cloud SQL or AlloyDB for PostgreSQL: No additional Database Migration Service charge (no DMS fee).
- For heterogeneous migrations, the first 500 GiB of backfill each month is free. Bytes are counted as raw (uncompressed) data.
CDC (Change Data Capture) — tiered, billed per GiB, per month, per account:
- 0–2,500 GiB: $2.00 per GiB, per month, per account
- 2,500–5,000 GiB: $1.50 per GiB, per month, per account
- 5,000–10,000 GiB: $1.20 per GiB, per month, per account
- 10,000 GiB and above: $0.80 per GiB, per month, per account (contact sales for pricing beyond 10 TiB)
Backfill — flat rate, billed per GiB, per month, per account:
- 0–500 GiB: $0.00 (Free) per GiB, per month, per account
- 500 GiB and above: $0.40 per GiB, per month, per account
Other notes:
- Usage billed in per-byte increments on a per-migration-job basis.
- Additional Google Cloud resource charges (Cloud SQL/AlloyDB instance costs, Compute Engine for reverse-SSH, network egress, etc.) apply separately.
- Region- and currency-specific SKUs may apply.
