WebFlux uses non-blocking IO, while Virtual Threads simulate concurrency with blocking IO.
WebFlux is designed for non-blocking, asynchronous processing, making it efficient for IO-bound operations. Virtual Threads allow blocking operations while handling many threads efficiently. In an e-commerce system, WebFlux is better for high-throughput APIs, while Virtual Threads might simplify blocking code compatibility.
