DB Instance Classes

General-enhanced and general-enhanced II instance classes provide robust and stable performance. They use latest-generation network acceleration engines and Data Plane Development Kit (DPDK) to provide higher network performance, meeting requirements in different scenarios.

General-enhanced DB instances use Intel® Xeon® Scalable processors and feature high and stable computing performance. Working in high-performance networks, general-enhanced DB instances provide higher performance and stability, meeting enterprise-class application requirements.
General-enhanced II DB instances use second-generation Intel® Xeon® Scalable processors with technologies optimized and 25GE high-speed intelligent NICs to offer powerful and stable computing performance, including ultra-high network bandwidth and PPS.
