Alibaba Group Holding Ltd. is taking the first steps toward revamping its cloud business by overhauling its leadership, aiming to revive growth and ride an AI boom after canceling a much-anticipated spinoff of the $11 billion unit.

The company has appointed three new executives to head up major business lines within Alibaba Cloud Intelligence, with two reporting directly to Chief Executive Officer Eddie Wu, a person familiar with the matter said. Key among those is the so-called public cloud — the domestic cloud services arm aimed at enterprise customers in China — which will be led by Liu Weiguang, the person said, asking not to be named as the plans are not public.
