How it works...

We have seen that the Network ACL with VPC and subnet allows all traffic. In the security group of the instance, we have opened HTTP protocol on port 80 for all incoming traffic. Internet Gateway is attached to the subnet in which we created the instance. During instance creation we have installed Apache, PHP and MySQL to host a website with page phpinfo.php. As we have enabled IPv4 and IPv6 in VPC, subnet and EC2, the EC2 instance has assigned those. So, after EC2 creation, we can access the website using the URL. The DNS name is resolved by AWS Route 53.
