ENA Express Extends High-Bandwidth Cross-AZ Traffic
⚡ ENA Express now supports high-bandwidth traffic between Amazon EC2 instances in different Availability Zones within a Region, delivering up to 25 Gbps single-flow performance. The feature uses the AWS Scalable Reliable Datagram (SRD) protocol with multi-pathing and advanced congestion control to reduce head-of-line blocking. ENA Express establishes SRD connections automatically when both instances are enabled and supports TCP and UDP transparently. The capability is available at no additional cost across a broad set of Regions and instance types.
