Cloud Week: AWS CEO Adam Selipsky, New Salesforce Co-CEO, Marvell and Snowflake Surprise

Adam Selipsky of AWS, Frank Slootman of Snowflake, Matt Murphy of Marvell Technology

It wasn't the most comfortable thing, flying to Las Vegas on Sunday for AWS's re:Invent conference, doing interviews Monday, and taking a red eye back to anchor TechCheck on CNBC Tuesday. But I was amped for Cloud Week, and was determined to fit it all in.

A few things about the week that keep replaying in my head:

• Enterprise infrastructure technology is still changing at a rapid clip, now at the level of custom chips, DevOps tools, industry-focused creative ideas, and focused partnerships.

• We're moving into yet another generation of CEO leaders, including Adam Selipsky at AWS and Bret Taylor at Salesforce, who bring new combinations of skills to the top.

• Cloud technologies are moving into spaces where skeptics thought they wouldn't. Nasdaq this week announced an aggressive move to the cloud for its matching engine, a system that needs extremely low latency.

Some exclusive interviews with some of the most impactful leaders in enterprise tech, below:
