Tiering EC2 Security Groups
In eight steps, students rewrite three-tier EC2 Security Group rules so each tier admits only the tier in front of it, then show with nc that the web tier can no longer reach the database.
How this lab runs
Small steps
Ordered so a student can tell whether each one worked before moving on — and so you can see which one they stalled on.
Yours to change
Add steps, cut steps, or rewrite the one your class keeps getting stuck on.
Launched from your LMS
Students open the lab from your course. No separate account or signup.
A real AWS account
Each student gets credentials and console access to a live account.
Graded automatically
Work is checked against what was actually built, and the score returns to your gradebook.
Cleaned up after
The account is torn down when the lab ends, so nothing keeps running.
