Last year Amazon introduced their first 64-bit Arm-based ECS2 "A1" instances which were found to deliver up to 45% cost savings over x86 Instances for the right workloads.
A few months ago, AWS (Amazon Web Services) provides a new offering with bare-metal A1 instances, and with re:invent 2019 now taking place the company has unveiled AWS ECS2 6th generation Arm instances (which they did not call A2 instances yet) powered by Graviton 2 processor comprised of custom Arm Neoverse N1 cores and promising up to 7x the performance of the original A1 instances.
