[how-to] Enable Internet Access in AWS with an Internet Gateway (IGW) | Step by Step Tutorial

Welcome to Bhagaskara Labs!
In this video, we’ll take a deep dive into AWS Internet Gateway (IGW) and show you how to enable internet access for your workloads inside a VPC.
An Internet Gateway is a horizontally scaled, highly available, and fully managed AWS component that connects your VPC to the internet. Without it, your VPC stays private and isolated. With it, your resources can communicate with the outside world — for example, to host websites, connect with users, or reach external APIs and services.

This tutorial is a complete step-by-step hands-on guide where you’ll see exactly how to set up, test, and verify internet connectivity using an IGW.
What you’ll learn in this video:
📖 What is an Internet Gateway (IGW) and how it works in AWS
💡 Why we need IGW and common use cases
🏗️ Create VPC, Subnet, and Route Table as the foundation
💻 Launch EC2 instance and install Apache HTTP server
🔍 Test connectivity before IGW (fails, as expected)
🔗 Create and attach Internet Gateway to the VPC
📡 Update Route Table with 0.0.0.0/0 → IGW for internet traffic
🎉 Test connectivity after IGW (success — page loads!)

By the end of this tutorial, you’ll clearly understand how IGW works and how to set it up properly for internet access in AWS.
