Stephanie Wong talks with guests Shachar Guz, Inna Weiner, and Gabe Weiss about Google’s Database Migration Service and how it helps companies move data to Google Cloud. What typically is a complicated process, DMS simplifies everything from planning to security to validating database migrations.

DMS has undergone some changes since last we spoke with Shachar and Gabe. It’s gone GA and helped thousands of customers benefit from the service. Migrations are possible from any PostgreSQL database source to AlloyDB for PostgreSQL, which is designed to support HTAP data (transactional and analytical). One of the most exciting updates is the introduction of the DMS modernization journey, which allows customers to change database type during migration (heterogenous). In addition, migrations with DMS can be set up to continuously replicate data between the old and new database. With this feature, developers can compare the application performance against the old vs. new database.

Inna talks about the benefits of keeping your data in the cloud, like secure, reliable, and scalable data storage. Google Cloud takes care of the maintenance work for you as well. DMS takes security seriously and supports multiple security methods to keep your data safe as it migrates. We talk about the different customers using DMS and how the process works for homogeneous and heterogeneous migrations. Before you even start, Gabe tells us, DMS helps you prepare for the migration. And tools like Dataflow can help when customers decide full migration would be too difficult. We talk about the difference between Datastream and DMS and use cases for each.

We wrap up the show with a look at the future of DMS.
