Amazon held its 10th re:Invent conference this week. The annual event, held this year in Las Vegas as well as online, reveals new technologies designed to support its Amazon Web Services (AWS) arm, one of the leading platforms for cloud computing. The tech giant's first AWS re:Invent in 2012 was a humble affair with only 6,000 attendees, dominated by startups and emerging technology partners. The in-person event featured keynote speakers, announcements about its latest tech innovations, as well as training and certification opportunities. Amazon revealed the latest it has to offer, but a few announcements took center stage.
