Dedicated General-Purpose ECSs

Overview

Compared with general-purpose ECSs, dedicated general-purpose ECSs provide the combinations of vCPUs and memory with larger specifications. In addition, the ECSs use latest-generation network acceleration engines and Data Plane Development Kit (DPDK) to provide higher network performance.

C6s ECSs use second-generation Intel® Xeon® Scalable processors that feature low latency and high performance, stability, and cost-effectiveness. They are suitable for Internet, gaming, and rendering scenarios, especially those that require high computing and networking performance.

C6 and C6nl ECSs use second-generation Intel® Xeon® Scalable processors to provide powerful and stable computing performance. By using 25GE high-speed intelligent NICs, they offer ultra-high network bandwidth and packets per second (PPS).

C7n ECSs use third-generation Intel Xeon scalable processors with enhanced performance, security, and stability. They can have a maximum number of 96 vCPUs and a memory speed of 3,200 MHz, and provide a secure, trusted cloud environment.
