"AWS recently announced the new Graviton5 processor and the preview of the first EC2 instances running on it, the general-purpose M9g instances. According to the cloud provider, the latest chip delivers up to 25% higher performance than Graviton4, introduces the Nitro Isolation Engine, and provides a larger L3 cache, improving latency, memory bandwidth, and network throughput. According to the press release, the new Arm-powered EC2 M9g instances provide up to 192 CPU cores per instance. The higher core density reduces inter-core latency by up to 33% and increases bandwidth, improving scaling for workloads such as databases, analytics, application servers, gaming, and Electronic Design Automation (EDA)."
"Graviton5 adds the Nitro Isolation Engine to the Nitro System, a new engine that uses formal verification to prove that workloads are isolated from each other and from AWS operators. The engine has a small, verified codebase, and AWS will give customers access to the implementation and its proofs for review. Mohamed Mediouni, kernel/hypervisor engineer at AWS, writes: A vendor hypervisor (because that's what that actually means) - in practice, a replacement to KVM - is an interesting thing to have for sure. Let's see where this whole story will actually lead. The session " Introducing Nitro Isolation Engine: Transparency through Mathematics" was recently presented at re:Invent, and is now available on YouTube. According to Ali Saidi, VP and distinguished engineer at Amazon, "the Nitro Isolation Engine is harnessing Rust and formal verification to create a formally verified cloud hypervisor, pioneering a new standard for mathematically proven cloud security.""
Graviton5 is an Arm-based processor powering preview M9g general-purpose EC2 instances. The processor offers up to 25% higher performance than Graviton4, a larger L3 cache, and improvements in latency, memory bandwidth, and network throughput. M9g instances support up to 192 CPU cores per instance, reducing inter-core latency by up to 33% and increasing bandwidth to improve scaling for databases, analytics, application servers, gaming, and EDA workloads. Graviton5 integrates the Nitro Isolation Engine into the Nitro System, using formal verification and a small verified codebase to prove workload isolation and provide customers access to implementation and proofs. Graviton adoption on AWS has grown significantly.
