What is actually driving spend?
Use this hub when architecture, deployment, or traffic shape is making cost opaque and you need a clearer view of what to change first.
Topic hub
Cost Optimization
Architecture-driven FinOps, cost trade-offs, and the places optimization quietly turns into operational debt.
Questions this hub should help answer
Use the topic like a decision surface, not a tag archive.
What breaks when you optimize too hard?
InfraTales treats cost as an architecture decision surface, not a spreadsheet exercise. The right answer often depends on reliability and operational labor.
Need a structured review?
Use the resource library for cost-audit frameworks and then come back to the long-form reads for implementation detail.

AWS CDK S3 to Lambda via EventBridge: Full Cost and Architecture Breakdown
Most S3-to-Lambda setups skip CloudTrail data events entirely and pay for it later with brittle fan-out and zero audit trail. This post walks through a CDK TypeScript stack that routes S3 events through EventBridge properly — VPC placement, KMS encryption, Secrets Manager, cost model, and the failur

These pieces stay inside the same operating surface and are better for depth once you already have the context from the spotlight read.
