ecs.c9a.16xlarge by Alibaba Cloud

A compute-optimized instance featuring dedicated AMD EPYC cores and high network bandwidth for CPU-bound workloads.

Alibaba Cloud ecs.c9a.16xlarge is a compute-optimized instance featuring 64 dedicated vCPUs powered by an AMD EPYC 9T25 processor running at 2.7 GHz. Utilizing the KVM hypervisor on the x86_64 architecture, the instance provides 64 physical cores with a 1.0 thread-per-core configuration, ensuring dedicated execution resources without hyperthreading. It is equipped with 128.0 GB of system memory, providing a 2.0 GB per core ratio, and does not include local storage. Network performance is supported by a baseline bandwidth of 32 Gbps. Lacking integrated GPUs and local storage, this instance is designed for cost-efficient, CPU-heavy workloads. It is suited for compute-intensive tasks, batch processing, and distributed web serving applications that rely on network-attached storage.
