For Amazon Route 53, improvements I see include the need for a DNS firewall and a domain-based SSL checker security feature. DNS security is the most important part for me. I feel that whenever you host any kind of website, the first and most important thing is to protect it with a valid SSL. The secure socket layer is essential for the HTTPS green lock in the browser. If I forget to deploy SSL on a website and if my domain hosting is under Amazon Route 53, there should be a mechanism that Amazon Route 53 protects the insecure website using SSL, a thing that the end user does not know whether the SSL certificate comes from the domain, meaning from Amazon Route 53 or from the website.
