Server Description
A dedicated sixty-four core compute-optimized instance featuring AMD EPYC processors and thirty-two gigabits per second baseline network bandwidth.
Alibaba Cloud ecs.c9a.16xlarge is a compute-optimized virtual machine instance featuring 64 dedicated x86_64 vCPUs powered by AMD EPYC 9T25 processors running at 2.7 GHz. Built on the KVM hypervisor, the instance provides 128.0 GB of system memory, establishing a 2.0 GB RAM-to-vCPU ratio. It does not include local storage or GPU hardware, meaning all storage operations rely on network-attached volumes. Network performance is supported by a baseline bandwidth of 32 Gbps. The dedicated CPU allocation guarantees predictable execution for processing-heavy applications. This configuration offers qualitative cost efficiency for deployments requiring high compute density without the added expense of excess memory or local storage. It is suited for batch processing, web serving, and compute-intensive application workloads.
