100 Days 100 AWS Projects (Complete Guide) - AWS VPC Explained: Like a House for Your Servers (Public vs. Private) | Day 5/100

Welcome to Day 5 of my #100DaysOfAWS journey! ☁️ If you missed Day 4 where we built a High-Availability Web App with Load Balancers, check it out here: https://youtu.be/3w89I7XxKG8 Project Resources: Github Repository: https://github.com/Priyanshu885588/100-days-100-aws-projects/blob/main/day05-AWS%20VPC%20Foundations/README.md In today's project, we are tackling the "backbone" of AWS: Networking. Deploying resources in a default VPC is easy, but it’s not secure for production. Today, we are building a custom Virtual Private Cloud (VPC) from scratch. Think of it as building a secure house for your servers. We create a "Front Porch" (Public Subnet) for our web traffic and a "Locked Vault" (Private Subnet) to keep our sensitive databases hidden from the internet. We’ll also set up the "Front Door" (Internet Gateway) and a "One-Way Security Exit" (NAT Gateway) so our private servers can get updates without being exposed to hackers. What You Will Learn Today: ✅ VPC Fundamentals: Creating an isolated network boundary with custom IPv4 CIDR blocks. ✅ Public vs. Private Subnets: Understanding why and how to separate your web tier from your data tier. ✅ Internet Gateway (IGW): Connecting your VPC to the world and managing Route Tables. ✅ NAT Gateway: Providing secure, one-way internet access to instances in a private subnet. ✅ Network Security: Using Route Tables to strictly control how data flows in and out of your architecture.
