• AWS News Blog AWS Weekly Roundup: Amazon EC2 M8azn instances, new open weights models in Amazon Bedrock, and more (February 16, 2026) | I joined AWS in 2021, and since then I’ve watched the Amazon Elastic Compute Cloud (Amazon EC2) instance family grow at a pace that still surprises me. • From AWS Graviton-powered instances to specialized accelerated computing options, it feels like every few months there’s a new instance type landing that pushes performance boundaries further. • As of February 2026, AWS offers over 1,160 Amazon EC2 instance types, and that number keeps climbing. • This week’s opening news is a good example: The general availability of Amazon EC2 M8azn instances. • These are general purpose, high-frequency, high-network instances powered by fifth generation AMD EPYC processors, offering the highest maximum CPU frequency in the cloud at 5 GHz. • Compared to the previous generation M5zn instances, M8azn instances deliver up to 2x compute performance, 4.3x higher memory bandwidth, and a 10x larger L3 cache.
