How do you set up replication for AWS Database Migration Service
The AWS Database Migration Service (DMS) is a managed, independent service that allows quick and secure database migration to the cloud from on-premises databases running on AWS EC2 instances, or from databases running on other types of databases. It allows you to manage, modify, and move your AWS cloud configurations.
AWS DMS interacts with your source data store through a replication instance, reads the source data, and formats it for consumption by the target data store. A replication instance loads data into the destination data store as well. Hence, replication is an integral part of AWS DMS. In this blog we will explain you in brief about how you can set up replication for AWS DMS.
Steps for setting up replication for AWS DMS
Create a replication instance: Open the AWS DMS console after logging in to the AWS Management Console, and then create a replication instance to perform your migration.
Declare the endpoints: The source and target data store endpoints for the previously constructed Amazon RDS databases can be specified when your replication instance is being set up.
Create a task and migrate the data: By creating a task, you construct a task in this stage to finally migrate the data between your newly formed databases.
Replication testing: In this step, you check the target database for the inserted data in this part after inserting data into the source database, both during and after the first replication.
Cleansing: In this final step, you can get rid of the resources you made. You can eliminate them using the AWS console. An important point to be noted is that you need to be sure to remove the migration jobs before the replication instance and endpoints.
As per the steps discussed above, you might have a decent understanding of how to set up a replication for AWS DMS and why replication is important for the migration process.
However, if you are planning to introduce AWS DMS to your organisation on real grounds, creating the replication instance can prove to be a little challenging and overwhelming. This is an area where experts guidance is recommended. But don’t worry, as we got you covered.
