New Amazon EC2 C8gn instances powered by AWS Graviton4 offering up to 600Gbps network bandwidth
Cloud amazon, AWS, Cloud, NewsToday, we’re announcing the general availability of Amazon Elastic Compute Cloud (Amazon EC2) C8gn network optimized instances powered by AWS Graviton4 processors and the latest 6th generation AWS Nitro Card. EC2 C8gn instances deliver up to 600Gbps network bandwidth, the highest bandwidth among EC2 network optimized instances.
You can use C8gn instances to run the most demanding network intensive workloads, such as security and network virtual appliances (virtual firewalls, routers, load balancers, proxy servers, DDoS appliances), data analytics, and tightly-coupled cluster computing jobs.
EC2 C8gn instances specifications
C8gn instances provide up to 192 vCPUs and 384 GiB memory, and offer up to 30 percent higher compute performance compared Graviton3-based EC2 C7gn instances.
Here are the specs for C8gn instances:
| Instance Name | vCPUs | Memory (GiB) | Network Bandwidth (Gbps) | EBS Bandwidth (Gbps) |
|---|---|---|---|---|
| c8gn.medium | 1 | 2 | Up to 25 | Up to 10 |
| c8gn.large | 2 | 4 | Up to 30 | Up to 10 |
| c8gn.xlarge | 4 | 8 | Up to 40 | Up to 10 |
| c8gn.2xlarge | 8 | 16 | Up to 50 | Up to 10 |
| c8gn.4xlarge | 16 | 32 | 50 | 10 |
| c8gn.8xlarge | 32 | 64 | 100 | 20 |
| c8gn.12xlarge | 48 | 96 | 150 | 30 |
| c8gn.16xlarge | 64 | 128 | 200 | 40 |
| c8gn.24xlarge | 96 | 192 | 300 | 60 |
| c8gn.metal-24xl | 96 | 192 | 300 | 60 |
| c8gn.48xlarge | 192 | 384 | 600 | 60 |
| c8gn.metal-48xl | 192 | 384 | 600 | 60 |
You can launch C8gn instances through the AWS Management Console, AWS Command Line Interface (AWS CLI), or AWS SDKs.
If you’re using C7gn instances now, you will have straightforward experience migrating network intensive workloads to C8gn instances because the new instances offer similar vCPU and memory ratios. To learn more, check out the collection of Graviton resources to help you start migrating your applications to Graviton instance types.
You can also visit the Level up your compute with AWS Graviton page to begin your Graviton adoption journey.
Now available
Amazon EC2 C8gn instances are available today in US East (N. Virginia) and US West (Oregon) Regions. Two metal instance sizes are only available in US East (N. Virginia) Region. These instances can be purchased as On-Demand, Savings Plan, Spot instances, or as Dedicated instances and Dedicated hosts.
Give C8gn instances a try in the Amazon EC2 console. To learn more, refer to the Amazon EC2 C8g instance page and send feedback to AWS re:Post for EC2 or through your usual AWS Support contacts.
