  • Glue : Data ETL Service - It is designed to help users to prepare and transform data for analytics and other downstream processing tasks. It automates many ETL tasks , making it easier to move and transform data from valrious sources to data lake, data warehouse or other sources.

  • Athena : Query service for S3 - It is an interactive query service that allows you to analyze data stored in Amazon S3 using standard SQL queries.

As we saw in the above post there are lots of features available in AWS and as we use AWS we become used to these terminologies. Even if we are not working with AWS the terminologies mentioned above are easy to remember since most of these are the features we have been aware of in any other clould environment or even in on premise environment.
