Setting Up Change Notifications

You can sign up to receive notifications when AWS prices change, such as when AWS cuts prices, when new instance types are launched, or when new services are introduced. You can sign up to be notified every time a price changes, or once a day. If you sign up to be notified once a day, the notification includes all price changes applied during that day.

To sign up for price update notifications

You can use the console to sign up for Amazon SNS notifications.

  1. Sign in to the AWS Management Console and open the Amazon SNS console at https://console.aws.amazon.com/sns/v2/home.

  2. If you are new to Amazon SNS, choose Get Started.

  3. If necessary, change the region on the navigation bar to US East (N. Virginia). The billing metric data is stored in this region, even for resources in other regions.

  4. On the navigation pane, choose Subscriptions.

  5. Choose Create Subscription.

  6. For Topic ARN, if you want to be notified every time a price changes, enter arn:aws:sns:us-east-1:278350005181:price-list-api. If you want to be notified about price changes once a day, enter arn:aws:sns:us-east-1:278350005181:daily-aggregated-price-list-api instead.

  7. For Protocol, use the default HTTP setting.

  8. For Endpoint, choose the format that you want to receive the notification in, such as SQS, Lambda, or email.

  9. Choose Create Subscription.

If you signed up for once a day notifications, the email has multiple update sections.

The email notification looks like this:
