Azure Web PubSub

Azure Web PubSub handles real-time messaging through serverless WebSocket and PubSub protocols. It manages bi-directional communication for scalable applications, letting you push data to clients without maintaining persistent connections or managing infrastructure overhead. The service abstracts the complexity of maintaining open sockets, focusing purely on message delivery and subscription management.

This setup suits teams building live dashboards, chat apps, or collaborative tools where instant updates are critical. The main friction point is the lack of a free tier; you pay strictly on a usage-based model from the start. There is no sandbox for testing, so every connection and message incurs cost immediately, which requires careful budgeting for development environments.
