Amazon RDS Multi-AZ instances now use ENA Express for replication traffic between Availability Zones. ENA Express uses AWS's Scalable Reliable Datagram (SRD) protocol to optimize network performance by delivering up to 25 Gbps single-flow bandwidth for cross-AZ replication traffic leveraging advanced congestion control and multi-pathing capabilities, and reducing latency variability for Multi-AZ deployments. RDS Multi-AZ instances replicate data synchronously to a standby in a different Availability Zone to provide high availability and automatic failover. AWS SRD, used by ENA Express, improve
Cloud providers are continuously optimizing their infrastructure to meet growing demands for performance and resilience, a necessary evolution to maintain competitive advantage and customer satisfaction.
This upgrade significantly improves the performance and reliability of critical database infrastructure, directly impacting business continuity and data-intensive applications leveraging AWS.
Database replication within AWS Multi-AZ deployments is now faster and more stable, reducing failover times and data latency for users relying on Amazon RDS.
- · AWS customers dependent on RDS for high availability
- · Cloud infrastructure providers prioritizing network optimization
- · Businesses with high-transaction database workloads
Improved performance and reduced latency for Multi-AZ RDS databases.
Increased confidence in AWS's ability to maintain high availability for critical workloads, potentially encouraging broader adoption of RDS.
This could set a new benchmark for cross-AZ replication performance, potentially pushing other cloud providers to accelerate their own network optimization efforts.
