Azure Web PubSub is a cloud service that helps developers easily build real-time features in web applications with publish-subscribe patterns at scale. Any scenario that requires real-time messaging between server and clients or among clients following publish-subscribe patterns can benefit from using Web PubSub. Developers no longer need to poll the server by sending repeated HTTP requests at intervals, which is wasteful and hard-to-scale. As shown in the diagram below, your clients establish WebSocket connections with your Web PubSub resource. This client library:

- simplifies managing client connections
- simplifies sending messages among clients
- automatically retries after unintended drops of client connection
- reliably deliveries messages in number and in order after recovering from connection drops
