AWS's serverless BI, billed per session instead of per seat.
Amazon QuickSight became generally available in November 2016 as AWS's native cloud BI service, built around SPICE (Super-fast, Parallel, In-memory Calculation Engine), an in-memory columnar store that holds dataset extracts for fast dashboard queries. The pricing model is the unusual part: Authors pay a monthly seat (Standard at $24/user, Author Pro at $40/user), while Readers can be billed per active session ($0.30 per 30-minute session, capped at $5/user/month) or per seat. That per-session option is why QuickSight shows up so often as the engine behind embedded customer-facing analytics, where seat counts would be unworkable.
The platform layers Amazon Q in QuickSight on top, generally available since April 2024, for natural-language questions, dashboard summaries and generative dashboard authoring. Native connectors lean heavily into the AWS stack: S3, Athena, Redshift, Aurora, RDS, OpenSearch, Timestream and the Glue Data Catalog, plus the usual Snowflake, BigQuery and Databricks for cross-cloud setups. The strength is the AWS gravity: if your data already sits in S3 or Redshift, QuickSight is a single VPC hop away. The weakness is the same one that hits Power BI and Tableau pages: SPICE refreshes multiply, capacity bills creep, and embedded sessions stack up across tenants. We curate the warehouse so SPICE holds a small set of well-shaped tables and the per-session bill tracks actual reader behaviour.
