Creating a Secure EC2 Infrastructure with NAT Gateway and VPC

In this video, you’ll learn how to build a secure and scalable EC2 infrastructure on AWS using a custom Virtual Private Cloud (VPC) with both public and private subnets, a NAT Gateway, and a Bastion Host. This hands-on project walks you through setting up a production-style cloud environment by launching two EC2 instances—one in a public subnet acting as the Bastion Host and another in a private subnet for secure operations. You’ll configure route tables, Internet Gateway, and a NAT Gateway to enable internet access for your private EC2 without exposing it directly to the internet. Along the way, you’ll set proper security group rules, use SSH keys to access instances, and test connectivity from the private EC2 via the NAT Gateway. This project is ideal for students, cloud beginners, and aspiring DevOps engineers, as it demonstrates a real-world AWS architecture used in professional environments to maintain both accessibility and security. By the end of the tutorial, you’ll gain valuable hands-on experience with AWS networking services and understand how to design and deploy a secure, cloud-based infrastructure using best practices.
