Realtime websites with publication and subscription

摘要

Architecture that utilizes a long poll publication/subscription (pubsub) model for updating realtime objects of a webpage. Each realtime-enabled object is a pubsub entity in a pubsub service. Each rendering of the webpage creates a subscription on a page object. The entity in the pubsub service enables the realtime communications of content to the webpage object. The architecture provides light-weight realtime anonymous pubsub at scale, a light-weight pubsub that can scale to the web on the backend, and integration into existing website code by plugging in at the javascript level.
