Amazon EC2 Instances
Utilize the new Amazon EC2 C8g and M8g instances to run your general-purpose and compute-intensive tasks sustainably. Today Amazon EC2 C8g and M8g instances are now widely available.
AWS C8g
High-performance computing (HPC), batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, and ad serving are suited for AWS Graviton4-based C8g instances.
AWS M8g
M8g instances, which are also Graviton4-based, offer the best cost-performance for workloads with a generic purpose. Applications like gaming servers, microservices, application servers, mid-size data storage, and caching fleets are all well suited for M8g instances.
Let’s now have a look at some of the enhancements it has implemented in these two cases. With three times as many vCPUs (up to 48xl), three times as much memory (up to 384GB for C8g and up to 768GB for M8g), seventy-five percent more memory bandwidth, and twice as much L2 cache as comparable 7g instances, C8g and M8g instances offer higher instance sizes. This allows processing larger data sets, increasing workloads, speeding up results turnaround, and lowering TCO.
These instances have up to 50 Gbps network bandwidth and 40 Gbps Amazon EBS capacity, compared to Graviton3-based instances’ 30 Gbps and 20 Gbps. C8g and M8g instances, like R8g instances, have two bare metal sizes (metal-24xl and metal-48xl). You can deploy workloads that gain from direct access to real resources and appropriately scale your instances.

Important things to know
With pointer authentication capability, separate caches for each virtual CPU, and always-on memory encryption, AWS Graviton4 processors provide improved security.
The foundation of these instances is the AWS Nitro System, a vast array of building blocks that assigns specialized hardware and software to handle many of the conventional virtualization tasks. It reduces virtualization overhead by providing great performance, high availability, and excellent security.
Applications written in popular programming languages such as C/C++, Rust, Go, Java, Python,.NET Core, Node.js, Ruby, and PHP, as well as containerized and microservices-based applications like those running on Amazon Elastic Kubernetes Service (Amazon EKS) and Amazon Elastic Container Service (Amazon ECS), are ideally suited for the C8g and M8g instances.
Available right now
The US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Frankfurt) AWS Regions currently offer C8g and M8g instances. With Amazon EC2, as usual, you only pay for the resources you utilize. See Amazon EC2 Pricing for additional details.
