ecs.r9ae.8xlarge by Alibaba Cloud

A dedicated AMD EPYC instance featuring a high memory-to-CPU ratio for demanding in-memory databases and data processing workloads.

Alibaba Cloud ecs.r9ae.8xlarge is a memory-optimized instance featuring 32 dedicated vCPUs and 256 GB of RAM, establishing a 1:8 resource ratio. Powered by an AMD EPYC 9T95 processor operating at 2.25 GHz on the x86_64 architecture, the instance allocates one thread per physical core across 32 physical cores under the KVM hypervisor. It does not include local storage, relying instead on network-attached storage, and provides a baseline network bandwidth of 16 Gbps. The dedicated CPU allocation ensures predictable performance without hyperthreading overhead. This configuration is qualitatively cost-effective for memory-intensive applications that demand stable, dedicated compute resources. It is highly suited for workloads such as in-memory databases, caching layers, and large-scale data processing.
