Managing cost control for cross-Region data sharing

With Amazon Redshift, you can manage cost control for cross-Region data sharing by configuring data sharing to limit the amount of data that is transferred between AWS Regions. Managing cost control for cross-Region data sharing allows you to set data transfer limits, monitor data transfer usage, and receive notifications when approaching or exceeding those limits.

When consuming data from a different Region, the consumer pays the Cross-Region data transfer fee from the producer Region to the consumer Region. The price of data transfer is different for different Regions. The charge is based on the bytes of data scanned for every successful query run. For more information about Amazon Redshift pricing, see Amazon Redshift pricing.

You are charged for the number of bytes, rounded up to the next megabyte, with a 10MB minimum per query. You can set cost controls on your query usage and view the amount of data being transferred per query on your cluster.

To monitor and control your usage and associated cost of using cross-Region data sharing, you can create daily, weekly, monthly usage limits, and define actions that Amazon Redshift automatically takes if those limits are reached to help maintain your budget with predictability. For more information about usage limits in Amazon Redshift, see Managing usage limits in Amazon Redshift.

Depending on the usage limits you set, actions that Amazon Redshift takes can be to log an event to a system table, send a CloudWatch alarm and notify an administrator with an Amazon SNS, or to turn off cross-Region data sharing for further usage. For more information about the actions, see Managing usage limits in Amazon Redshift.

To create usage limits in the Amazon Redshift console, choose Configure usage limit under Actions for your cluster. You can monitor your usage trends and get alerts on usage exceeding your defined limits with automatically generated CloudWatch metrics from the Cluster performance or Monitoring tabs. You can also create, modify, and delete usage limits programmatically by using the AWS CLI or Amazon Redshift API operations. For more information, see Managing usage limits in Amazon Redshift.
