ecs.c9h.4xlarge by Alibaba Cloud

A dedicated x86_64 compute instance with a one-to-one core-to-thread ratio, designed for predictable, non-vectorized processing workloads.

Alibaba Cloud ecs.c9h.4xlarge is a compute-optimized instance featuring 16 dedicated vCPUs and 16 physical cores powered by an x86_64 Hygon 7447v processor running at 2.6 GHz. With a single thread per core configuration, it provides predictable compute performance. The instance is equipped with 32.0 GB of RAM, establishing a 1:2 vCPU-to-RAM ratio. It features a baseline network bandwidth of 7 Gbps and does not include local storage, requiring network-attached storage for data persistence. Notably, the processor configuration lacks advanced instruction sets such as AVX, AVX512, AMX, and hardware-accelerated cryptographic flags like AES. This instance is designed for sustained, compute-bound workloads such as web serving, application hosting, and distributed batch processing where specialized vector instructions and local storage are not required.
