Understanding the Components of AWS DMS

Are you considering AWS DMS solutions for your data migration? You can move data more effectively and gain more knowledge when troubleshooting or doing investigations if you are aware of the fundamental parts of AWS DMS. Today in this blog, we will provide you with an overview of the structural components of AWS DMS and how they work together to carry out your data migration.

AWS DMS migrations consist of three components: a replication instance, source and target endpoints, and a replication task. Let’s study these components below in brief.

The Main Components of AWS DMS

Replication Instance – The replication instance is created on an Amazon EC2 instance via AWS DMS. Some of the more compact instance classes are adequate for service testing or quick migrations. Consider selecting one of the larger instances, if your migration involves a significant number of tables or if you want to conduct several replication processes at once. Depending on the features of your migration and the replication server’s capability, a single replication instance may host one or more replication processes. You can select the best configuration for your use case by using one of the replication instances offered by AWS DMS.

Endpoint – The endpoint cannot be used in a DMS job until the test is successful. The AWS DMS console requests to test the endpoint connection once you create an endpoint. Similar to the connecting details, different engine types have distinct requirements for precise test criteria. AWS DMS generally checks to make sure the database is present at the specified server name and port and that the provided credentials can be used to connect to the database with the requisite access rights to complete a migration. AWS DMS downloads and stores schema data if the connection test is successful so it can be used later during task configuration.

Replication Tasks – An AWS DMS replication task is used to transfer a set of data from the source endpoint to the target endpoint. You must complete one final activity before beginning a migration, which is creating a replication task.

The following task options are available when you create a replication task:

  • Source endpoint
  • Target endpoint
  • Migration

Data migration from the source endpoint to the target endpoint is accomplished via the job, that is processed on the replication instance or specific processing, such as logging needs, control table data, and error handling.

Bottom line

If you are looking for implementing AWS DMS technology in your organization on a long-term basis, creating the replication instance can be difficult and time-consuming.
