ecs.c9ae.4xlarge by Alibaba Cloud

A compute-optimized instance featuring dedicated AMD EPYC cores and a balanced memory-to-CPU ratio for predictable execution.

Alibaba Cloud ecs.c9ae.4xlarge is a compute-optimized virtual machine instance built on the KVM hypervisor. It is equipped with 16 dedicated x86_64 vCPUs powered by an AMD EPYC 9T95 processor operating at 2.25 GHz. Because the instance features a 1.0 thread-per-core configuration, each vCPU corresponds to a dedicated physical core, ensuring consistent execution. The hardware profile includes 32.0 GB of system memory, providing 2.0 GB per core, with no local storage or GPU accelerators bundled. Network performance is anchored by a 10 Gbps baseline bandwidth. This resource configuration is designed for compute-heavy workloads such as batch processing, web serving, and dedicated application servers that require predictable CPU allocation without the overhead of hyperthreading or the need for high memory-to-CPU ratios.
