Investing.com -- Amazon.com Inc will see the departure of Dave Brown, a senior vice president in Amazon Web Services, after 19 years with the company. Brown is a member of the S-team, the internal group that advises CEO Andy Jassy.

AWS CEO Matt Garman announced the move in an internal memo cited by Reuters, stating that Brown is leaving for another position. Garman did not specify details about Brown's next role. Brown most recently led compute and machine learning services at AWS.
