What is VPC, Subnet, Internet Gateway? AWS Networking Basics

In this tutorial, I'll guide you through the process of setting up a Virtual Private Cloud (VPC) on AWS. We'll cover creating a VPC, setting up public and private subnets, launching EC2 instances, configuring an Internet Gateway (IGW), creating route tables, and enabling NAT Gateway for internet access from private instances.

I'll also demonstrate how to connect to the public EC2 instance using EC2 Instance Connect and then SSH into the private EC2 instance from the public EC2 instance. This tutorial is designed to help you understand the fundamentals of VPC networking on AWS and how to securely connect instances within a VPC.

At the end of the tutorial, we'll cover how to clean up and delete all the resources we've used, ensuring that you're not incurring any additional costs. This step is crucial to maintain a clean AWS environment and avoid unnecessary charges.
