Solutions Architect Associate Hands-On Labs

A build-it-yourself lab track for the Solutions Architect - Associate (SAA-C03) material in The Exam Room. The Associate paper rewards knowing what a service actually does when you wire it up, which is hard to fake and easy to build. Each lab gives you a working base (CloudFormation plus a couple of scripts) and asks you to build the piece that carries the decision. You deploy real AWS resources, prove the behaviour, and tear them down.

The idea: scaffolding that fades

Same shape as the other tracks. Early labs are almost finished and you fill one clearly-marked gap; later labs hand you less. Every lab ships a solution/ you can deploy at any point (SRC=solution), so you are never stuck.

Scaffold What you’re given What you do
5/5 Everything but one value or resource Fill the gap, deploy, prove it
3/5 Infra, no wiring Connect the pieces
1/5 A requirement and a skeleton Design and build most of it
0/5 A requirement Build it from scratch

Before your first lab

Do the one-time, once-per-account setup: run preflight.sh (it ships in every lab zip) to confirm your account is ready, then deploy the lab reaper once. The reaper auto-deletes any lab you forget to tear down after 24 hours, so a forgotten stack becomes a deleted stack instead of a running bill. Every lab’s deploy.sh tags its stack for the reaper automatically.

The arc

The track walks the four SAA-C03 domains, numbered in publication order, so labs 02 and 03 share a day: the fleet in the morning, the failover that evening. It grows over time; the table marks what is built and what is on the bench.

Labs 03, 04 and 05 are syntax-checked but have not been deployed against a real AWS account end to end. Neither have 01 and 02. Treat a first run as the shakedown.

The zips are built by scripts/build-lab-zips (also make lab-zips) into zips/labs/ and committed, so they publish with the site. Re-run it whenever a lab changes.
