The original title is: "Let Aurora Sleep: Multi-Tenant SaaS Cost, Reconsidered with AI IaC"

Short summary

For early-stage SaaS and dev environments, Aurora-centric architecture incurs high fixed costs even during idle periods due to always-on compute, NAT provisioning, and connection pooling. The author proposes demoting Aurora to a thin control plane (auth, audit, approval) while moving hot paths (viewing, LLM calls, ephemeral state) to S3, CloudFront, DynamoDB, and non-VPC Lambda. Using AI-assisted IaC design and Serverless v2's min_acu=0, this approach makes architectural restructuring accessible to non-specialists while maintaining compliance isolation.

• •Aurora becomes control/audit plane only; demote it from every request path
• •Hot paths (viewing, LLM calls, cache) move to S3/CloudFront/DynamoDB/Lambda
• •Fixed costs drop by eliminating always-on compute, NAT, and connection pooling
