Amazon has promoted the Vice Presidents of its two primary businesses to newly created CEO positions.

The ecommerce giant announced in a blog post on Thursday that Jeff Wilke of Worldwide Consumer and Andy Jassy of Amazon Web Services (AWS) had both been made CEOs of their respective companies. The positions were made specifically for them, as “recognition of the roles they‘ve played for a while.”

“As we‘ve grown as a company and those three big pillars [referring to each aspect of the Amazon business that now has its CEO] have also grown, we‘ve decided it makes sense to change the titles of the leaders of those businesses – Jell Wilke and Andy Jassy – to CEO Worldwide Consumer and CEO Amazon Web Services,” the blog said.

This move will help mark Worldwide Consumer and AWS as distinct businesses. Now sporting three CEOs, Amazon will nonetheless still remain firmly under the control of Jeff Bezos, who tweeted his congratulations following the announcement.

“Thank you and congrats to my friends and colleagues Jeff and Andy – very well deserved!”

The promotions raised long standing questions about Bezos‘ succession plan. In an interview with Business Insider he confirmed that one existed but refused to go into greater detail.
