Service Comparison

Athena vs Redshift

Serverless S3 SQL and managed warehouse analytics are not the same workload.

What They Have in Common

Each option can solve part of the scenario. The exam expects you to choose the one that satisfies the stated constraints with the right operational burden, security boundary, availability model, and cost behavior.

Key Differences

Option	Primary model	Best use	Security	Availability	Operations and cost
Athena	Serverless SQL over S3	Ad hoc queries, logs, data lake exploration	Pay by scanned data
Redshift	Data warehouse	High-performance BI, complex joins, concurrency, modeled analytics	Capacity/storage cost
