AWS Charges When Deploying AWS Q Developer and QuickSight Q Subscriptions

When deploying Amazon Q Developer and QuickSight Q subscriptions, here's what you should know about the pricing and potential charges:

For Amazon Q Developer Pro subscriptions:

• The pricing is user-based at $19 per user per month
• Billing is handled at the AWS organization level if you have AWS Organizations set up, with the management account receiving the bill
• If you don't have AWS Organizations, the AWS account under which users are subscribed gets billed
• If you unsubscribe users, billing stops at the end of the billing cycle
• You won't be double-billed if the same user is subscribed in multiple accounts within the same organization

For Amazon Q in QuickSight:

• There are Author and Reader plans
• Author plans cost $24/user/month
• Reader plans cost $3/user/month
• Reader Pro plans cost $20/user/month and add generative BI capabilities

Both services follow a subscription-based pricing model that is straightforward and predictable. The billing for these services appears in the Billing and Cost Management console under "Q" in the "Charges by service" tab.

Regarding your specific questions:

1. These services don't automatically provision underlying AWS resources that would continue to incur charges after cancellation. The subscription model is designed to be straightforward with costs tied directly to user licenses.

2. Based on the available information, there are no mentioned data retention or backup features that would store logs or query history in other AWS services requiring manual cleanup after cancellation.

3. The sources don't provide specific information about costs associated with exporting QuickSight Q reports or factors that might contribute to those charges.

4. The sources don't provide information about whether Amazon QuickSight Q can connect to a database hosted on an EC2 instance in a private subnet.

To track and allocate costs for Amazon Q Developer subscriptions, you can use AWS Cost and Usage Reports (CURs) with the "Include resource IDs" option selected when creating data exports. This allows you to identify costs for specific users through resource IDs.
