ecs.r9ae.xlarge by Alibaba Cloud

A memory-optimized virtual server featuring dedicated AMD EPYC cores and a high memory-to-vCPU ratio for memory-intensive workloads.

Alibaba Cloud ecs.r9ae.xlarge is a memory-optimized instance featuring 4 vCPUs and 32.0 GB of system memory, establishing a 1:8 vCPU-to-RAM ratio. Powered by an AMD EPYC 9T95 processor running at 2.25 GHz on the x86_64 architecture, the instance provides 4 dedicated physical cores with a single thread per core under the KVM hypervisor. It lacks local storage and GPU accelerators, relying on external storage solutions and offering a baseline network bandwidth of 4 Gbps. The absence of hyperthreading ensures dedicated execution resources per vCPU. This configuration is designed for memory-intensive workloads such as caching systems, in-memory databases, and data processing applications that require a high memory-to-core ratio without the need for local NVMe storage or hardware acceleration.
