AWS EC2 instances now support ENA queue allocation for your network interfaces
News
AWS has introduced a new feature for Elastic Network Adapter (ENA) that provides flexible queue allocation for Elastic Network Interfaces (ENIs) on EC2 instances.
- Enables dynamic allocation of ENA queues across network interfaces
- Optimizes networking performance by distributing packet processing across vCPUs
- Provides granular control over network resources and instance performance
- Allows customers to align queue allocation with specific workload requirements
- Previously, ENA queues were statically allocated without flexibility
The new feature allows network-intensive applications to be allocated more queues, while CPU-intensive applications can use fewer queues. It is now available in all AWS Commercial Regions.
