Pricing and billing
Learn about the pricing model and billing structure for DataStax Astra DB serverless and databases.
Classic databases can no longer be created through Astra Portal. We recommend migrating your database to our current serverless option, which could save you money and allow you to manage your compute and storage capabilities separately.
Pricing for Astra DB classic databases is based on plan, units of measure, cloud provider, and region.
The cost of your classic Astra DB database depends on the classic database plan you select. Classic Astra DB databases use a single capacity unit (CU) by default, which represents three database instances that are grouped together for three replicas. The classic database plan represents the amount of compute power allocated to each CU, and represents three compute instances per CU. Classic database pricing is presented in the DataStax Astra Portal in hourly terms, but billed in one-minute granularity.
In addition, all Astra Classic customers are charged additional data transfer cost as state below:
Data transfer (GB): the transfer of Customer Data out of the database. Billable units and pricing vary depending on whether the Data Transfer occurs within the same region of a cloud provider network (“Data Transfer - Same Region”), across regions within the same cloud provider network (“Data Transfer - Cross Region within Cloud Provider Network”), or leaves the cloud provider network over the internet (“Data Transfer - Internet”).
If data transfer is within the same region of the same Cloud Service Provider (e.g. application and database are both in AWS us-east-1), no data transfer charges are incurred, effective July 1, 2022.
You can select AWS, Google Cloud, or Azure as your cloud provider. Each cloud provider offers Standard, Premium and Premium+ regions. The cloud provider and region you select affects the price of each unit of measure for your database.
Effective July 1, 2022, there is no separate premium pricing for Astra Classic Multi-region. All Astra Classic customers are charged additional data transfer cost. Data Transfer pricing is the same as Astra Serverless pricing. For more details on the definitions of "Multi-Region" and "Data Transfer" as well as respective pricing, please visit the Astra Serverless pricing page.
Astra DB handles billing through an integration with Stripe, and displays all related billing information in the Billing & Payments section of your Organization.
In Billing & Payments, you can see your plan and payment method, along with when the plan was created. You can also select Manage to change your plan.
You can also update your payment method in the Billing & Payments section. Your Billing & Payments also displays each database included in your server, allowing you to see what your total cost is per database.
