During the course of serving 1.3 billion users on Alipay, Ant Group found itself living with a multitude of computing paradigms (such as AI, graph, and streaming) This brought about challenges in performance and development efficiency. Ant Group has used Ray to build a fusion engine to break computing boundaries and improve development and performance efficiency.
In Charles's keynote, he will introduce that in the process of large-scale production of the fusion engine, Ray's production cluster has reached 200K core at Ant Group, becoming the world’s largest Ray cluster in production. Meanwhile, we have enhanced various aspects of Ray Core's feature. In addition, Charles will discuss the achievements of the Fusion Engine last year and his vision for the future of Fusion Computing.
