So who took over some of Suresh's responsibilities? Two executives are Noelle Walsh-Elwell and Rani Borkar. Here is a Microsoft article that describes their roles.

Noelle Walsh-Elwell, Corporate Vice President of Global Data Center Operations
Rani Borkar, Corporate Vice President of Cloud Supply Chain and Provisioning”
