- Configure network interfaces as EFA-only or standard ENI on EFA-capable instances
- EFA-only interfaces don't consume IP addresses, optimizing VPC IP utilization
- Launch EC2 instances using cluster, spread, or partition placement strategies
- Control physical distribution of instances across AWS infrastructure
- Optimize for performance, availability, and fault isolation in distributed workloads
- Available in all AWS Regions where Amazon EKS is available
These capabilities enable fine-grained control over network configuration and instance placement for distributed training and inference workloads on Kubernetes.
