I've stumbled upon Amazon's SQS offering, a messaging queue that's targeted at producer consumer solutions running in the cloud.
I'm attempting to build a proof of concept in my own private cloud for a larger solution that will run within the amazon cloud.
Does the Ubuntu Enterprise Cloud (Eucalyptus) provide an equivalent service to Amazon's SQS?
Does SQS conform to any sort of Messaging standard, so that I could use another open source implementation?
