Amazon will be the talk of Black Friday and Cyber Monday, but if you follow the money the more important event this week may be Amazon Web Services' re:Invent conference in Las Vegas. Rest assured Amazon's e-commerce division will get most of the headlines this week, but you'd be an idiot to ignore the AWS roadmap and customer powwow taking place right after Cyber Monday concludes. Why? AWS' re:Invent conference has become a big customer event where the company outlines its AI roadmap, new services and architecture overview. And if the economy goes shaky and consumer spending falters a bit, Amazon's market capitalization will be mostly driven by AWS, which is the public cloud computing leader. Certainly, Amazon's operating income will be driven by AWS even more than it is now.
