Amazon EC2 C6g Instances
High price performance for compute-intensive workloads in Amazon EC2
Overview
Amazon EC2 C6g instances are powered by Arm-based Amazon Graviton2 processors. They deliver up to 40% better price performance over C5 instances and are ideal for running advanced compute-intensive workloads. This includes workloads such as high performance computing (HPC), batch processing, ad serving, video encoding, gaming, scientific modelling, distributed analytics, and CPU-based machine learning inference.
C6g instances are available with local NVMe-based SSD block-level storage option (C6gd) for applications that need high-speed, low latency local storage. C6g instances with 100 Gbps networking and Elastic Fabric Adapter (EFA) support, called the C6gn instances, are also available for applications that need higher networking throughput, such as high performance computing (HPC), network appliance, real-time video communication, and data analytics.
Benefits
With C6g instances, customers can optimize for both higher performance and lower cost per vCPU. C6g instances deliver up to 40% better price performance over C5 instances1 for a large number of applications built on open-source software utilizing Linux distributions.
C6g instances add to the broadest and deepest selection of EC2 instances and enable customers to run a broad set of compute-intensive workloads such as high performance computing, gaming, and machine learning inference. With C6gn and C6gd instances, customers can also run workloads that require high performance networking as well as those that need access to local NVMe-based SSD storage. Additionally, developers can build Arm applications natively in the cloud while leveraging the flexibility, security, reliability and scalability of running on EC2.
C6g instances are powered by Amazon Graviton2 processors and built on the Amazon Nitro System. Amazon Graviton2 processors feature always-on 256-bit DRAM encryption and 50% faster per core encryption performance compared to first-generation Amazon Graviton. The Amazon Nitro System is a combination of dedicated hardware and lightweight hypervisor which delivers practically all of the compute and memory resources of the host hardware to your instances for better overall performance and security. C6g instances also support encrypted EBS storage volumes by default.
Amazon Graviton2-based EC2 instances are supported by popular Linux operating systems including Amazon Linux 2, Red Hat, SUSE, and Ubuntu. Many popular applications and services from Amazon Web Services and Independent Software Vendors also support Amazon Graviton2-based instances, including Amazon ECS, Amazon EKS, Amazon CodeBuild, Amazon CloudWatch, Crowdstrike, Datadog, Docker, Drone, Dynatrace, GitLab, Jenkins, NGINX, Qualys, Rancher, Rapid7, Tenable, and TravisCI.
Features
Amazon Graviton2 Processors are based on 64-bit Arm Neoverse cores and custom silicon designed by Amazon Web Services for optimized performance and cost. Amazon Graviton2 Processors deliver 7x more performance, 4x more compute cores, 5x faster memory, and 2x larger caches versus first-generation Amazon Graviton Processors.
C6gn instances provide up to 100 Gbps networking bandwidth with support for Elastic Fabric Adapter (EFA). They also provide up to 38 Gbps EBS bandwidth, which is more than 2x compared to C5n instances. C6g instances are also available with NVMe-based SSD local instance storage option (C6gd).
The Amazon Nitro System is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software to deliver high performance, high availability, and high security while also reducing virtualization overhead.
