Can I point my domain and subdomains to AWS hosting without using Route 53?

I have some xyz.com domain name (purchased from GoDaddy), and also I need 3 more subdomains like a.xyz.com, b.xyz.com, c.xyz.com. My question is without using AWS Route 53 service(Which is not free) can I point my domain and all subdomains to my AWS ec2 instance folders through A records and configuring .htaccess file ?

You would need to:

• Assign an Elastic IP address to each Amazon EC2 instance (this is a static IP address that will not change)
• Create an A-Record in your DNS provider that points to the Elastic IP address
