Technical deep-dives on AWS cost optimization, cloud waste detection, and FinOps automation.
A deploy from a laptop and a deploy from CI landed 18 seconds apart. The pipeline went red — and production quietly kept running the OLD build anyway. The real bug wasn't the error message; it was that the error message never named the actual consequence.
AWS Cost Explorer's own data can lag up to 24 hours, and nobody's on call for 'the bill.' Here's the actual statistics behind CloudWise's daily anomaly scan — a real z-score threshold from the shipped code, and the exact test case that proves it catches a spike.
Our /dashboard cold start took 1,124ms. SnapStart was already on, already restoring in ~600ms — and it made zero measurable difference for two deploys, because of a log level and a hook that only half-did its job. Here's the actual debugging path, including the parts that didn't work.
CloudWise's onboarding flow can never touch your infrastructure — it only ever grants a bespoke, Get/Describe/List-only IAM role. Remediation lives in a separate, opt-in stack behind an explicit approval gate. Here's the actual IAM, not the marketing version.
EBS snapshot costs are real, but Cost Explorer can't tell you which AMI or volume is causing them. Here's the billing blind spot, the AMI-pinning trap, and what our detector actually checks.
A wrong password on the CloudWise login page returned HTTP 500 — on staging AND production — for who knows how long. It went unnoticed until an E2E gate's negative-path test caught it and blocked a release. Here's the fix, and why status codes are a contract, not a suggestion.
NAT Gateway costs don't show up as their own line — they hide inside 'Amazon Virtual Private Cloud' next to a dozen other charges. Here's what CloudWise's detector actually checks before it tells you to delete one, and the gap it doesn't cover yet.
We ran CloudWise's own scan engine against a realistic mid-size SaaS AWS bill and it came back with $11,871/mo in savings across 18 findings. Here's what was actually in it — and why the biggest opportunities weren't the ones you'd expect.
Every AWS cost tool has a 'buy this Reserved Instance' button. I almost shipped one. Here's why I built a Commitment Risk Score instead — and the four signals it checks before it will ever recommend a commitment.
