Amazon EC2 C8g Instances

Best price performance for compute-intensive workloads in Amazon EC2

Why Amazon EC2 C8g Instances?

Amazon Elastic Compute Cloud (Amazon EC2) C8g instances, powered by the latest-generation AWS Graviton4 processors, provide the best price performance in Amazon EC2 for compute-intensive workloads. Amazon EC2 C8g instances are ideal for compute-intensive workloads, such as high performance computing (HPC), batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, and ad serving. C8g instances offer up to 30% better performance and larger instance sizes with up to 3x more vCPUs and memory than the seventh-generation AWS Graviton3-based C7g instances.

Benefits

C8g instances deliver up to 30% better performance over Graviton3-based C7g instances. These instances include DDR5-5600 memory and are ideal for compute-intensive workloads, such as HPC, batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based ML inference, and ad serving.

C8g instances are built on the AWS Nitro System. The AWS Nitro System is a combination of dedicated hardware and a lightweight hypervisor that delivers isolated multitenancy, private networking, and fast local storage.

AWS Graviton-based instances are supported by most popular Linux operating systems. Many popular applications and services for security, monitoring and management, containers, and continuous integration and delivery (CI/CD) from AWS and software partners also support AWS Graviton-based instances. The AWS Graviton Ready program offers certified solutions from AWS Partner software vendors that you can use on AWS Graviton-based instances.

Features

AWS Graviton4 is the latest generation of server processors designed by AWS that provide the best performance and energy efficiency for workloads in Amazon EC2. AWS Graviton4 processors deliver up to 30% better compute performance than Graviton3 processors.

AWS Graviton4 processors offer enhanced security with always-on memory encryption, dedicated caches for every vCPU, and support for pointer authentication. C8g instances also support encrypted Amazon Elastic Block Store (Amazon EBS).

The AWS Nitro System is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software. It delivers high performance, high availability, and high security, thus reducing virtualization overhead.

Customer testimonials

Here are some examples of how customers and partners have achieved their business agility, price performance, cost savings, and sustainability goals with Amazon EC2 C8g instances.

  • Quora

    We migrated our Python webservers to the AWS Graviton3-based Amazon EC2 C7g instances. We observed an up to 30% improvement in price performance compared to the leading x86-based Amazon EC2 instances available at that time. This motivated us to migrate many more services to Graviton, including asynchronous task workers (Airflow, email servers), data processing engines (Spark, Trino), and caching servers (Memcached, Redis). Remarkably, we saw similar great performance improvement and cost reduction in all of the systems we migrated. Graviton has become a key pillar in our cost-management strategy, enabling us to save costs while delivering a fast and responsive product experience to our users. We are excited about AWS Graviton4-based Amazon EC2 C8g instances with more performance and larger instance sizes and expect it to further help our existing and new workloads.

  • Arctic Wolf

    Arctic Wolf is the leader in security operations. Using the cloud-native Arctic Wolf Platform, we help organizations end cyber risks by providing security operations as a concierge service. All Arctic Wolf solutions were developed in collaboration with AWS. Our relationship ensures Arctic Wolf technology, processes, and services fully utilize AWS advanced computing including AWS Graviton-based Amazon EC2 instances, storage, networking, and more. With AWS Graviton3-based Amazon EC2 M7g instances we achieved up to 20% performance and 17% price-performance improvement over comparable x86-based instances. With the launch of Graviton4-based Amazon EC2 M8g instances we look forward to further improve both customer efficiencies and experience through greater performance and sustainability benefits.

  • IBM

    IBM Instana Observability automatically discovers, maps, and monitors all services and infrastructure components, providing complete visibility across your application stack.

    At its core Instana is a real-time streaming analytics platform. We collect, process, analyze, and store petabytes of data in order to build a digital twin of the observed environments. This means handling one-second granularity metrics and 100% of IT request traces, along with logs, events, performance profiles, and other data. Performance and efficiency are key to the way we run our platform at scale. We previously transitioned to AWS Graviton3-based Amazon EC2 C7g, M7g, and R7g instances across our distributed microservice and datastore deployments.This helped us achieve up to 35% reduction in CPU utilization with 18% lower cost. AWS Graviton4 takes us beyond that. Our tests show further reduction in CPU utilization by up to 30%. At the same time, it improved our platform’s responsiveness and query times. With the release of the new Graviton4-based C8g and M8g instances, we’re now in a position to adopt Graviton4 to optimize the price performance of all varieties of our workloads.
