I used Pingdom to test the response time of an Amazon EC2 (Elastic Compute Cloud) instance and a DynDNS Spring Server. Both are virtual server offerings. DynDNS’s Spring Server was marginally faster in terms of ping response time.
After using both for the past few months, I have found that the DynDNS Spring Server is much easier to get started with initially, but Amazon’s EC2 is much more flexible.
