FREE AWS Networking Simulator Study Tool
Hey everyone! Some of you may remember my AWSomecards.com flashcards I shared here a while back — the response was awesome, so I wanted to share something new I’ve been building: TransitLab.io, a free tool to help people actually understand AWS networking concepts.
What I’ve built:
- Interactive labs — e.g. visualize how traffic flows
- Editable example labs — labs can be modified to suit your needs
- Covers most core networking: VPCs, subnets, route tables, IGWs, NAT gateways, peering, Transit Gateway
- Completely FREE (no paywall or signup required)
Why I built this:
Networking was the hardest part of AWS for me to truly get rather than memorize. I failed my ANS exam last year, and I realized I needed some more hands on experience to understand the networking concepts. So I built TransitLab to fix that for myself, and figured it might help others prepping for SAA-C03, ANS-C01, or anyone who wants networking to finally click. Unfortunately, if you’re not aware, AWS is retiring the ANS-C01 exam in August; so I probably won’t retake the exam, but since I built it, I decided to share it anyway just in case it could help out the community anyways.
Perfect for:
✅ Solutions Architect Associate/Professional prep
✅ Advanced Networking Specialty prep (until certification exam retirement)
✅ Filling in conceptual gaps notes/theory can’t cover
✅ Quick review before an exam

It's designed to cover the things that aren't the easiest to understand or conceptualize. But anyway, let me know if something doesn’t work, and I’ll do my best to fix it.
Just a heads up, the simulator is meant for desktop access only due to the design layout, so no mobile or desktop - sorry 😭.
