Hands-on cloud architecture, built on Saturday and torn down by Sunday night.
A private S3 bucket behind CloudFront, a subdomain handed to Route 53 without touching the email on the parent domain, and an Astro site that reads its posts straight from the lab folders.
Reference tables kept current with MERGE, an hourly-partitioned enriched table, and the time-travel trick that keeps old flows labeled the way they were.
I streamed 70,000 synthetic VPC flow records into an Iceberg table, then tried schema evolution, time travel and row-level deletes, and waited for a compaction that never came.
Centralized versus distributed inspection, and what each one costs per hour before a single packet flows.
Pointing this blog's own AWS bill at Athena, one weekend at a time.
Same flow logs as Lab 01, queried two ways, with the per-GB math side by side.
