During Monday Night Live, Amazon Web Services (AWS) VP of global infrastructure Peter DeSantis made a slew of announcements ahead of the cloud giant's annual re:Invent conference in Las Vegas. But the announcement that received the loudest reception from the audience was the AWS Graviton processor. When AWS acquired Annapurna Labs in 2015, the company started to think about building a custom CPU that could scale on the cloud, DeSantis said. The result is EC2 A1, built around Arm cores and touted as a great fit for scale-out workloads where the load can be shared across a group of smaller instances. It's the first time Arm processors have been made available in the cloud.
