ecs.r9i.large by Alibaba Cloud

A memory-optimized virtual server featuring dedicated Intel Xeon processors and high memory density for memory-bound enterprise workloads.

Alibaba Cloud ecs.r9i.large is a memory-optimized virtual machine instance designed for workloads requiring a high memory-to-CPU ratio. Built on the KVM hypervisor and the x86_64 architecture, it features 2 dedicated vCPUs mapped to 2 physical cores of an Intel Xeon 6982P-C processor running at 3.2 GHz. The instance provides 16.0 GB of RAM, resulting in 8.0 GB of memory per core, but lacks local storage and GPU resources. Network performance is defined by a baseline bandwidth of 2 Gbps. Because it offers dedicated CPU allocation and a high memory density without the overhead of local disks, this instance is qualitatively cost-effective for memory-bound applications. It is suited for workloads such as small-scale databases, caching layers, and enterprise applications that require consistent compute performance and a larger memory footprint relative to the virtual core count.
