💡 Check With Vendor
Verify these considerations match your specific requirements:
- Multi-cloud or non-AWS replication targets.
- Users who need a simple UI without understanding AWS infrastructure.
🏆 Alternatives
Compared to third-party tools, DMS is natively integrated into AWS, simplifying security, billing, and management. While it may not have as broad support for non-AWS targets as tools like Qlik Replicate, it is highly optimized for its primary purpose.
