A Terraform configuration that provisions the following infrastructure:
A VPC with:
- Public subnets for external resources.
- Private subnets for internal resources.
EC2 instances:
- Deployed within the private subnets.
- Running a web server that displays the hostname of the instance which received the request.
Requirements:
Autoscaling:
Configure the EC2 instances to scale based on demand using AWS Auto Scaling Groups.
Expose the web application:
Make the web application reachable from the internet while keeping the EC2 instances in the private subnets.
