AWS Database Migration Service (DMS)
- AWS DMS is a cloud service that makes it easy to migrate relational databases, data warehouses, NoSQL databases.
- Using AWS DMS, we can perform one-time migration or replicate ongoing changes to keep sources and targets in sync
- If you want to migrate to a different database engine, AWS provides AWS Schema Conversion Tool (AWS SCT)
- DMS Architecture
- Source Endpoint is connection to the source database
- Target Endpoint is connection to the target database
- When you configure DMS, you would configure replication, Which is performed by an Replication Instance (Which in turn is a database)
Target Database
- Lets create an AWS mysql RDS instance with db instance size
db.t2.micro(free tier)
Endpoints
-
Navigate to the database migration service
-
Lets create a source endpoint which connects to our simulated on-premise db
- Now lets create target endpoint
