Where this fits in the platform
This lab adds
- vpc_id, public and private subnet ids, route tables, NAT gateway
Before you start
Cost — Billable
The NAT Gateway is ~$0.045/hour (~$32/month) plus $0.045/GB processed, and it bills whether or not traffic flows. The VPC, subnets and route tables are free. Destroy the NAT Gateway the moment you are done.
The goal#
Build AWS VPC, Subnets, Gateways & Route Tables yourself, starting from an empty directory, without following the guided steps.
Everything you need is in the criteria above. Work down them one at a time, and verify each before moving to the next.
Hands-on environment
Run this lab in a real terminal, free and in your browser. The environment is temporary and yours alone — break it as much as you like.
Start the challengeOpens in Killercoda, in a new tab — keep this page open for the steps.
This is the guided lab's environment — the same machine, with its walkthrough on the left. Work from the task above and leave those steps alone until you are done, or you are reading the answers.
Run it on AWS
This lab builds real cloud infrastructure, so it needs your own AWS account. Follow the cost and cleanup notes above — the resources are yours, and so is the bill.
Anything you tick here is your own record. EgyKode cannot see inside that terminal, so the success criteria stay self-assessed even when the environment checks your work for you.
Rules#
- Do not open the guided lab until you have genuinely tried.
- When something fails, read the error before you search. The error message is the lesson.
- Tear down anything billable as soon as you finish.
If you get stuck#
The guided lab is one click away at the bottom of this page. Using it is not failure — coming back and repeating the challenge afterwards is the point.
