Amazon's future is in flux under new CEO Andy Jassy

Amazon is in the midst of the biggest leadership overhaul in its history. That's put the future in flux and sowed seeds of doubt about the western world's largest e-commerce and cloud-computing company.

Can the $1.6 trillion behemoth keep growing after a giant pandemic sales boost in 2020? The shares have stagnated in the past year, while the rest of the stock market roared ahead. There's a new CEO, Andy Jassy, who recently took over from founder Jeff Bezos. Will Jassy run the tech giant as well as his former boss? 

Here's a rundown of the must-know news at Amazon, including the latest hires and exits, as well as deep dives on the AWS cloud business, new robot and drone projects, and the company's controversial performance-improvement plans. 

With Jassy as CEO and Bezos becoming executive chairman this year, there's been a scramble for leadership positions beneath them, as well as many departures.
