Working with Endpoints in AWS Database Migration Service

An endpoint provides connection, data store type, and location information about your data store. AWS Database Migration Service uses this information to connect to a data store and migrate data from a source endpoint to a target endpoint. You can specify additional connection attributes for an endpoint by using extra connection attributes. These attributes can control logging, file size, and other parameters; for more information about extra connection attributes, see the documentation section for your data store.

Following, you can find out more details about endpoints.

Creating Source and Target Endpoints

While your replication instance is being created, you can specify the source and target data stores. The source and target data stores can be on an Amazon Elastic Compute Cloud (Amazon EC2) instance, an Amazon Relational Database Service (Amazon RDS) DB instance, or an on-premises database.

The procedure following assumes that you have chosen the AWS DMS console wizard. Note that you can also do this step by selecting Endpoints from the AWS DMS console's navigation pane and then selecting Create endpoint. When using the console wizard, you create both the source and target endpoints on the same page. When not using the console wizard, you create each endpoint separately.

To specify source or target database endpoints using the AWS console

  1. On the Connect source and target database endpoints page, specify your connection information for the source or target database. The following table describes the settings.

                        Create source and target DB endpoints
    For This Option Do This

    Endpoint identifier

    Type the name you want to use to identify the endpoint. You might want to include in the name the type of endpoint, such as oracle-source or PostgreSQL-target. The name must be unique for all replication instances.

    Source engine and Target engine

    Choose the type of database engine that is the endpoint.

    Server name

    Type the server name. For an on-premises database, this can be the IP address or the public hostname. For an Amazon RDS DB instance, this can be the endpoint (also called the DNS name) for the DB instance, such as


    Type the port used by the database.

    SSL mode

    Choose an SSL mode if you want to enable connection encryption for this endpoint. Depending on the mode you select, you might be asked to provide certificate and server certificate information.

    User name

    Type the user name with the permissions required to allow data migration. For information on the permissions required, see the security section for the source or target database engine in this user guide.


    Type the password for the account with the required permissions. If you want to use special characters in your password, such as "+" or "&", enclose the entire password in curly braces "{}".

  2. Choose the Advanced tab, shown following, to set values for connection string and encryption key if you need them. You can test the endpoint connection by choosing Run test.

    Extra connection attributes

    Type any additional connection parameters here. For more information about extra connection attributes, see the documentation section for your data store.

    KMS master key

    Choose the encryption key to use to encrypt replication storage and connection information. If you choose (Default) aws/dms, the default AWS Key Management Service (AWS KMS) key associated with your account and region is used. For more information on using the encryption key, see Setting an Encryption Key and Specifying KMS Permissions.
