This post walks through my first Terraform assignment — provisioning a real, working AWS environment from scratch.

What I Built

Resource Name Details

VPC Terraform-vpc 10.0.0.0/16

Internet Gateway Terraform-igw Attached to the VPC

Public Route Table Terraform-public-rt Routes 0.0.0.0/0 → IGW

Public Subnet Terraform-public-subnet 10.0.1.0/24 , auto-assigns public IPs

Private Subnet Terraform-private-subnet 10.0.2.0/24 , no public IP

Security Group Terraform-ec2-sg Allows SSH (22) and HTTP (80) inbound

EC2 Instance Terraform-ec2 t3.micro , Amazon Linux 2,…
