ecs.r9ae.4xlarge by Alibaba Cloud

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

Alibaba Cloud ecs.r9ae.4xlarge is a memory-optimized instance built on the KVM hypervisor and powered by an x86_64 AMD EPYC 9T95 processor running at 2.25 GHz. It features 16 dedicated physical cores with one thread per core, delivering 16 vCPUs and 128.0 GB of system memory. This configuration provides a high memory-to-vCPU ratio of 8.0 GB per core. The instance does not include local storage or complimentary public IPv4 addresses, but it provides a baseline network bandwidth of 10 Gbps. Designed without hyperthreading, the dedicated core allocation ensures consistent compute performance. This hardware profile is qualitatively cost-efficient for memory-bound applications that require predictable CPU execution. It is suitable for workloads such as in-memory databases, caching systems, and enterprise applications requiring significant memory capacity.
