This document discusses building serverless analytics solutions on AWS. It describes how AWS services like S3, Athena, and QuickSight can be used to build scalable and cost-effective data lakes, pipelines, and analytics. Serverless architectures with these services provide interactive queries, automated reporting, and visualization of data stored in S3 without having to manage infrastructure. The document also provides an example of how TrendMicro built a multi-account cost analytics solution using S3, Athena, and QuickSight to analyze billing data from hundreds of accounts.
