ecs.r9ae.large by Alibaba Cloud

A memory-optimized virtual instance featuring dedicated AMD EPYC processors and high memory density for memory-bound workloads.

Alibaba Cloud ecs.r9ae.large is a memory-optimized virtual machine instance from the ecs.r9ae family, running on the KVM hypervisor. It features an AMD EPYC 9T95 x86_64 processor operating at 2.25 GHz, delivering 2 dedicated vCPUs across 2 physical cores with a single thread per core. The instance is configured with 16.0 GB of RAM, establishing a high memory-to-vCPU ratio of 8.0 GB per core. It does not include local storage, requiring external network-attached storage solutions, and provides a baseline network bandwidth of 2 Gbps. With its dedicated CPU allocation and high memory density, this instance is designed for memory-sensitive workloads such as small-scale databases, caching layers, and memory-bound enterprise applications that require predictable performance without high compute core counts.
