c5d EC2 instances have internal NVMe storage. To use the advantage of NVMe internal disks in the terraform-aws-eks
module as a Launch Template for the Autoscaler Groups the support was added in the following PRs:
- https://github.com/terraform-aws-modules/terraform-aws-eks/pull/1213
- https://github.com/terraform-aws-modules/terraform-aws-eks/pull/1404
In case you need a cost-effective AWS instance with high throughput and amount of IOPS this should be a good choice for EKS instances. A drawback could be instance has a fixed disk size of the NVMe disk.
More information about c5 instances with local NVMe storage can be found here:
