Amazon Athena is designed for running interactive queries on data stored in Amazon S3 using standard SQL without the need to load the data into a separate analytics platform or data warehouse. Hence, for the described scenario where a company needs to run interactive SQL queries directly on their unstructured text data stored in S3, Amazon Athena is the best choice. Other data analytics services like Amazon Kinesis and AWS Glue would not be the best fit for this scenario. Amazon Kinesis is used for real-time data streaming and analytics, and AWS Glue is a fully managed extract, transform, and load (ETL) service that prepares and loads data for analytics, but neither provide the ability to run SQL queries directly on data stored in S3 like Athena does.
