Azure Front Door Standard and Premium now support WebSocket in general availability. WebSocket is enabled by default and requires no additional configuration.
WebSocket provides full-duplex communication over a single, long-lived TCP connection, enabling efficient, low-latency data exchange without the need for polling. This reduces overhead and improves resource utilization for real-time applications.
With native WebSocket support, Azure Front Door can power interactive and real-time scenarios such as chat applications, live dashboards, financial data streaming, gaming, and other continuous data workloads.
