China’s largest cloud service has begun informing affected staff, people familiar with the matter said. It’s offering severance to employees or transfers to other parts of the Alibaba empire, though those aren’t guaranteed, one of the people said. The moves are intended to streamline the business, which Alibaba aims to fully carve out into a separate company within a year, the person said, asking to remain anonymous discussing internal plans.

Alibaba Cloud is one of the biggest companies that will be created in a six-way split of the parent, joining other units such as the Cainiao logistics division and international commerce in pursuing independent fundraising and potential listings. The group, which doesn’t detail staffing at separate units, employed more than 235,000 people as of March.

Chief Executive Officer Daniel Zhang last week outlined details of the historic shakeup for the first time. That included a plan to fully relinquish control of the business known as Alibaba Cloud, a once-thriving operation that harbored the potential to supercharge the company the way Amazon Web Services grew to signify Amazon.com Inc.

Alibaba’s shares slid more than 1% in pre-market trading in New York.
