Where does Alibaba make most of its money?

I'm curious to understand where Alibaba, the Chinese e-commerce giant, generates the bulk of its revenue. Do they rely heavily on their e-commerce platforms like Taobao and Tmall, or do other services like cloud computing, digital media, and entertainment contribute significantly to their bottom line? Understanding the sources of Alibaba's primary income streams would help me grasp the company's overall business model and growth potential.
