HTTP Cloud Functions support multi-concurrency and WebSocket real-time communication
HTTP Cloud Functions now support single-instance multi-concurrency mode and WebSocket/SSE real-time communication. Development Documentation
Multi-concurrency reduces cold starts
A single function instance can handle multiple requests simultaneously, removing the need to start a new instance for every request. Compared to the "single instance single request" mode of regular cloud functions, it significantly reduces cold start frequency and resource consumption.
Bidirectional WebSocket communication
Native support for WebSocket protocol provides full-duplex communication. This is ideal for scenarios requiring bidirectional communication, such as real-time chat, collaborative editing, and game servers. WebSocket Usage Guide
