ComputeConfig - Amazon Database Migration Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

ComputeConfig

Configuration parameters for provisioning an Amazon DMS Serverless replication.

Contents

AvailabilityZone

The Availability Zone where the Amazon DMS Serverless replication using this configuration will run. The default value is a random, system-chosen Availability Zone in the configuration's Amazon Web Services Region, for example, "us-west-2". You can't set this parameter if the MultiAZ parameter is set to true.

Type: String

Required: No

DnsNameServers

A list of custom DNS name servers supported for the Amazon DMS Serverless replication to access your source or target database. This list overrides the default name servers supported by the Amazon DMS Serverless replication. You can specify a comma-separated list of internet addresses for up to four DNS name servers. For example: "1.1.1.1,2.2.2.2,3.3.3.3,4.4.4.4"

Type: String

Required: No

KmsKeyId

An Amazon Key Management Service (Amazon KMS) key Amazon Resource Name (ARN) that is used to encrypt the data during Amazon DMS Serverless replication.

If you don't specify a value for the KmsKeyId parameter, Amazon DMS uses your default encryption key.

Amazon KMS creates the default encryption key for your Amazon Web Services account. Your Amazon Web Services account has a different default encryption key for each Amazon Web Services Region.

Type: String

Required: No

MaxCapacityUnits

Specifies the maximum value of the Amazon DMS capacity units (DCUs) for which a given Amazon DMS Serverless replication can be provisioned. A single DCU is 2GB of RAM, with 1 DCU as the minimum value allowed. The list of valid DCU values includes 1, 2, 4, 8, 16, 32, 64, 128, 192, 256, and 384. So, the maximum value that you can specify for Amazon DMS Serverless is 384. The MaxCapacityUnits parameter is the only DCU parameter you are required to specify.

Type: Integer

Required: No

MinCapacityUnits

Specifies the minimum value of the Amazon DMS capacity units (DCUs) for which a given Amazon DMS Serverless replication can be provisioned. A single DCU is 2GB of RAM, with 1 DCU as the minimum value allowed. The list of valid DCU values includes 1, 2, 4, 8, 16, 32, 64, 128, 192, 256, and 384. So, the minimum DCU value that you can specify for Amazon DMS Serverless is 1. If you don't set this value, Amazon DMS sets this parameter to the minimum DCU value allowed, 1. If there is no current source activity, Amazon DMS scales down your replication until it reaches the value specified in MinCapacityUnits.

Type: Integer

Required: No

MultiAZ

Specifies whether the Amazon DMS Serverless replication is a Multi-AZ deployment. You can't set the AvailabilityZone parameter if the MultiAZ parameter is set to true.

Type: Boolean

Required: No

PreferredMaintenanceWindow

The weekly time range during which system maintenance can occur for the Amazon DMS Serverless replication, in Universal Coordinated Time (UTC). The format is ddd:hh24:mi-ddd:hh24:mi.

The default is a 30-minute window selected at random from an 8-hour block of time per Amazon Web Services Region. This maintenance occurs on a random day of the week. Valid values for days of the week include Mon, Tue, Wed, Thu, Fri, Sat, and Sun.

Constraints include a minimum 30-minute window.

Type: String

Required: No

ReplicationSubnetGroupId

Specifies a subnet group identifier to associate with the Amazon DMS Serverless replication.

Type: String

Required: No

VpcSecurityGroupIds

Specifies the virtual private cloud (VPC) security group to use with the Amazon DMS Serverless replication. The VPC security group must work with the VPC containing the replication.

Type: Array of strings

Required: No
