Astra DB plan options
DataStax Astra DB offers a serverless database, which is an elastic cloud-native database that scales with your workload. You can scale your compute and storage capabilities independently, allowing you to focus on developing your application and less on your infrastructure costs.
Astra DB offers three plans: Free, Pay As You Go, and Enterprise (annual commitment). Each plan is billed according to the Astra DB pricing, which is based on the Read and Write requests, data storage, and data transfer. For more, see DataStax Astra DB Pricing.
