How does Amazon Athena charge users for its service?

• A. By a monthly subscription fee
• B. By the number of queries executed per day
• C. By the amount of data scanned per query
• D. By the number of users accessing the service

Answer: (C)

Amazon Athena charges users based on the amount of data scanned per query. This means that users are billed according to the volume of data that the query reads, rather than a flat fee or subscription. This pricing model encourages users to optimize their queries and data layouts to minimize costs. For instance, using partitions or compressing data can lead to significant savings, as queries that scan less data incur lower charges. This pay-per-query and pay-per-scan model aligns with the serverless nature of Athena, making it cost-effective for users, as they only pay for what they use without needing to manage or provision infrastructure.
