Server Description
A compute-optimized virtual server featuring dedicated AMD EPYC processors and a balanced two-gigabyte-per-core memory configuration for consistent processing workloads.
Alibaba Cloud ecs.c9a.xlarge is an x86_64 compute-optimized virtual server powered by an AMD EPYC 9T25 processor running at 2.7 GHz. Built on the KVM hypervisor, this instance provides 4 dedicated physical cores with a single thread per core, ensuring consistent CPU performance without hyperthreading overhead. It is configured with 8.0 GB of system memory, establishing a 2.0 GB per core ratio. The instance features a baseline network bandwidth of 4 Gbps and does not include local storage, meaning all storage must be attached externally. With its dedicated CPU resources and compute-focused memory ratio, the ecs.c9a.xlarge is designed for workloads such as web serving, batch processing, and distributed compute tasks that require steady processing power without high memory demands.
