Is overseeing cloud operations the new career path to CEO?

When Amazon announced last week that founder and CEO Jeff Bezos planned to step back from overseeing operations and shift into an executive chairman role, it also revealed that AWS CEO Andy Jassy, head of the company's profitable cloud division, would replace him.

As Bessemer partner Byron Deeter pointed out on Twitter, Jassy's promotion was similar to Satya Nadella's ascent at Microsoft: in 2014, he moved from executive VP in charge of Azure to the chief exec's office. Similarly, Arvind Krishna, who was promoted to replace Ginni Rometti as IBM CEO last year, also was formerly head of the company's cloud business.

Could Nadella's successful rise serve as a blueprint for Amazon as it makes a similar transition? While there are major differences in the missions of these companies, it's inevitable that we will compare these two executives based on their former jobs. It's true that they have an awful lot in common, but there are some stark differences, too.

Replacing a legend

For starters, Jassy is taking over for someone who founded one of the world's biggest corporations. Nadella replaced Steve Ballmer, who had taken over for the company's face, Bill Gates. Holger Mueller, an analyst at Constellation Research, says this notable difference could have a huge impact for Jassy with his founder boss still looking over his shoulder.

There's a lot of similarity in the two situations, but Satya was a little removed from the founder Gates. Bezos will always hover and be there, whereas Gates (and Ballmer) had retired for good. [ ... ] It was clear [they] would not be coming back. [ ... ] For Jassy, the owner could [conceivably] come back anytime," Mueller said.

What Andy Jassy's promotion to Amazon CEO could mean for AWS

But Andrew Bartels, an analyst at Forrester Research, says it's not a coincidence that both leaders were plucked from the cloud divisions of their respective companies, even if it was seven years apart.

In both cases, these hyperscale business units of Microsoft and Amazon were the fastest-growing and best-performing units of the companies. [ ... ] In both cases, cloud infrastructure was seen as a platform on top of which and around which other cloud offerings could be developed," Bartels said. The companies both believe that the leaders of these two growth engines were best suited to lead the company into the future.
