Day 30 : Enable Internet Access for Private EC2 using NAT Instance

I'm Zin Lin Htet. Who love to learn and share about Linux, Cloud, Docker and K8s. Currently working as a DevOps Engineer at one of the famous Fintech Company in Myanmar.

Part of series100 Days of Cloud (AWS)

Welcome to Day 30. In this lab, you will learn how to enable internet access for a private EC2 instance using a NAT instance. You only need to set up an EC2 instance as a NAT instance.

What is a NAT Instance?

A NAT Instance allows private subnet instances to access the internet (outbound only) while blocking inbound internet traffic.

⚠️ AWS recommends NAT Gateway for most cases, but NAT Instance is still valid for:

Custom firewall rules
Cost optimization (very low traffic)
Legacy architectures

Congratulations you did it. It looks good. This lab was successfully completed without any errors. See you in day 31. If you have any issues please let me know I will be happy to assist you. Stay tuned and learn together. If you find my article useful, please kindly like and share it.
