🌐 AWS VPC Hands-On Project: Public & Private Subnets, EC2, NAT Gateway, and Bastion Host

This project is a complete hands-on demonstration of building a secure and scalable VPC on AWS, using the AWS Management Console (root user) to configure each resource manually. I created this to deepen my understanding of core AWS networking concepts and help others learn with a clear, step-by-step walkthrough.

🚀 What I Built

In this project, I created and configured:

• ✅ A custom VPC with a CIDR block of 11.0.0.0/16
• ✅ One Public Subnet (11.0.1.0/24) and one Private Subnet (11.0.2.0/24)
• ✅ An Internet Gateway for public access
• ✅ A NAT Gateway for secure outbound access from the private subnet
• ✅ Two EC2 instances:
  • Public EC2 with an Elastic IP (Bastion Host)
  • Private EC2 (accessed via the Bastion Host)
• ✅ Custom Route Tables for each subnet
• ✅ Security Groups to control traffic flow
