ecs.c9ae.xlarge by Alibaba Cloud

A compute-optimized virtual server featuring dedicated AMD EPYC cores and a balanced 1:2 CPU-to-memory ratio for predictable processing workloads.

Alibaba Cloud ecs.c9ae.xlarge is a compute-optimized virtual machine instance featuring 4 dedicated vCPUs and 4 physical cores powered by an AMD EPYC 9T95 processor running at 2.25 GHz. Built on the x86_64 architecture and managed via the KVM hypervisor, this instance provides 8.0 GB of system memory, resulting in a 2.0 GB per core ratio. It does not include local storage or integrated GPUs, relying instead on network-attached storage options. With a baseline network bandwidth of 4 Gbps and dedicated CPU allocation, the instance is designed to deliver consistent, non-shared processing power. This hardware profile is qualitatively cost-efficient for compute-bound tasks that require predictable CPU performance without high memory overhead, making it suitable for batch processing, microservices, and lightweight web serving.
