Basic VPC Design - Build using Terraform

  Make a basic custom VPC with a single Private and Public Subnet, loaded with an Internet and NAT Gateway using Terraform Script (infrastructure as code), Also Setup private and public routes and a security group to allow ipV4 traffic on port 22 & 80. Further Provision and launch the static website running on the private EC2 instance using Elastic Load Balancer DNS name.

VPC cidr IpV4 Class A CIRD (Classless interdomain routing)

# VPC IP range :
 10.0.0.0/26
   64 IPs
# Public Subnet cidr :
   10.0.0.0/28
   16 - 5 (11) IPs
# Private Subnet cidr :
   10.0.0.16/28
   16 - 5 (11)

private_key name : ssh1.pem

- file("~/.ssh/ssh1.pem")

Terraform Commands

#  First command to run for a new configuration
      terraform init
> terraform fmt
> terraform validate
> terraform apply
> terraform destroy
