pubsub appengine atom http webhooks

A simple, open, server-to-server web-hook-based pubsub (publish/subscribe) protocol as a simple extension to Atom.

A simple but clever way of using web hooks (HTTP callbacks) to inform subscribers that an Atom feed has updated in almost real-time.

A simple, open, web-hook-based pubsub protocol & open source reference implementation.

Une architecture distribuée de Pub/Sub avec HTTP

The best part about Webhooks is that most of us are already familiar with them: callbacks over HTTP. Pioneered by PayPal and Subversion as a way to send real-time notifications to the client, they have found their way into many dozens of products we all use every day. Need pre or post commit hooks for your SVN or Git repository? Both GitHub and SVN support HTTP callbacks. Need a payment alert from PayPal, or an alert when a wiki page is modified? There are webhooks for that too. This simple mechanism allows us to build web services that work together via a simple and ubiquitous protocol we can all understand: HTTP!

"We offer this spec in hopes that it fills a need or at least advances the state of the discussion in the pubsub space. Polling sucks. We think a decentralized pubsub layer is a fundamental, missing layer in the Internet architecture today and its existence, more than just enabling the obvious lower latency feed readers, would enable many cool applications, most of which we can't even imagine. But we're looking forward to decentralized social networking."

With all the recent buzz about real-time web, surely this is the year XMPP/AMQP Publish-Subscribe (PubSub) makes it to the big leagues! Or maybe not. Ejabberd (XMPP), RabbitMQ (AMQP) and other pubsub server implementations have come a long way but they remain cumbersome to setup and maintain,

WebHooks or PubSubHubBub are designed to simplify and optimize the web.

Amazon Simple Notification Service (Amazon SNS) is a web service that makes it easy to set up, operate, and send notifications from the cloud. It provides developers with a highly scalable, flexible, and cost-effective capability to publish messages from an application and immediately deliver them to subscribers or other applications. It is designed to make web-scale computing easier for developers.

Amazon SNS is a shot across Twitter's bow: an event update API is a critical component in an Internet of Things >> http://j.mp/9cpSVb
