Which web services is better?

[NeilS]

What are you actually planning to use it for? I'm also inclined to recommend AWS but would be good to know the use.

In my opinion, you should use Amazon web because they promise high speed and offer globally distributed DNS servers and a programmable interface. While GoDaddy doesn't offer a programmable interface.
If you choose Amazon web, you should use Amazon Route 53 with main reasons:

+ Amazon has clearly documented how their server setup is. They use Anycast, and have DNS servers in 15+ locations worldwide. Their service seems well engineered for high uptime.

+ Having your DNS resolve from 15+ locations worldwide makes your website a little bit faster for your end users. It also allows you to use a lower TTL, which means in case of a website failure, you can move your service over to a new IP faster.

+ In the future, Amazon plans to integrate Route53 with their other cloud offerings. If you uses some of these, such as EC2 and Elastic Load Balancer, then you will benefit from this integration. What they'll build isn't known yet, but one-step setup of Elastic Load Balancing and health check integration with CloudWatch seem like reasonable guesses.
