The business with which Jassy is most identified is Amazon Web Services, the unit that pioneered cloud computing, the business of renting space and software programming for customers to run their technical operations on the company's vast array of servers. Amazon had already developed the technology to run its own business when a group of executives, including Jassy, met during a brainstorming session in the living room of Bezos's Seattle-area home in 2003 and proposed offering unused computing storage and service to other businesses. "Andy pushed to get Amazon into a new business where it hadn't been," said a second former Amazon executive who also spoke on the condition of anonymity. The company launched AWS three years later, with Jassy at the helm. The unit upended the business software industry, putting giants such as IBM and Oracle, which were slower to pivot their offerings to cloud services, on their heels.
