Getting started with the Oracle Database@AWS high performance networking

This article provides a guide to Oracle Database@AWS high performance networking, which delivers sub-millisecond latency between EC2 applications and Oracle Exadata databases.

• Automatic EC2 placement groups minimize network hops and reduce latency variability
• Feature available for new ODB networks created after April 1, 2026 in supported regions
• No additional charge; works with existing EC2 APIs and capacity reservations
• Step-by-step setup: create ODB network, retrieve placement group ID, launch EC2 instances
• Placement groups shareable across AWS accounts within same organization via AWS RAM
• Use qperf, iperf3, or sockperf tools to measure and validate network latency
• Best practice: reserve placement groups for latency-sensitive workloads only

ODB@AWS high performance networking simplifies low-latency database connectivity for trading systems and OLTP workloads by automatically optimizing EC2 instance placement near Exadata infrastructure.
