General-Purpose DeHs
Overview
General-purpose DeHs can accommodate ECSs with regular workloads and short-term workload surges. They use a CPU-unbound scheduling scheme. vCPUs are randomly allocated to idle CPU hyper threads based on the system loads. If traffic loads are light, the computing performance is high. However, if traffic loads are heavy, vCPUs of different ECSs compete for physical CPU resources, resulting in unstable computing performance.
Currently, only the s3, s6, and s6_pro DeH types equipped with the latest-generation Intel® Xeon® Skylake CPUs, providing better cost-effectiveness, are provided and can be used to deploy S3 and S6 ECSs.
