SOAP vs REST at AWS
I found an interesting quote about SOAP API usage for Amazon’s Simple Storage Service:
We are continuing to support our existing SOAP APIs. That said, given that SOAP requests currently make up < 1% of our request volume in the US, we made the pragmatic decision to not extend the SOAP APIs as part of our EU launch. This allowed us to make our EU location available sooner than we could have otherwise.
It does not specifically say whether this is just for S3 but I think it is a good indication of REST popularity.
All my AWS code is also using the REST API’s. Much simpler and you don’t have to use bloated SOAP frameworks to get things done.
