I have a salesforce app that relies heavily on an external php application which is hosted on Amazon an Amazon EC2 instance.

I'd like to take advantage of the Amazon Simple Queue Service to send and receive all the data the 2 web services and exchanging. Amazon provide a php library I can use on my external app, but I'm going to need to implement it on force.com as well.

Has anyone had a look at using this service with force.com?

Does salesforce offer a similar service that I should look at using instead?

Thanks

Mike
