I just checked Amazon SNS service (beta) to see how it works, but I became really confuse about the technology behind Notification Service. I am not looking for specific IOS or Objective-C answer, also I know it may use an open TCP connection (with an open port or long pooling), but I am looking for some information regarding the technology behind it or any possible protocols.
Please Let me know if you have any short reference for that.
SNS is about publishing notifications (pubsub).
Once you have a topic, you can create subscriptions. A subscription is roughly made by a protocol and an identifier (email, url).
Once set, topics will broadcast the messages to its subscribers
One of those, however, is SQS, which allows Long Polling (up to 60s).
