Web Functions Request Concurrency: Single vs Multi-Concurrency Performance and Cost Analysis

Web Functions, which support native HTTP/WebSocket protocols, traditionally handle each request with a dedicated instance, but this single‑request concurrency wastes resources and raises costs for I/O‑intensive workloads; enabling multi‑request concurrency—either static or dynamic—consolidates many requests onto fewer instances, cutting latency by up to 80 % and reducing billing by as much as 98.8 %.
