ecs.r9i.4xlarge by Alibaba Cloud

A memory-optimized virtual instance featuring dedicated Intel Xeon cores and high memory density for predictable, memory-intensive enterprise workloads.

Alibaba Cloud ecs.r9i.4xlarge is a memory-optimized instance featuring 16 dedicated physical cores powered by an Intel Xeon 6982P-C processor running at 3.2 GHz on the x86_64 architecture. Operating under the KVM hypervisor, this instance provides 128.0 GB of RAM, establishing a high memory-to-core ratio of 8.0 GB per core. It does not include local storage, relying entirely on network-attached storage options, and delivers a baseline network bandwidth of 12 Gbps. With its dedicated CPU allocation and single thread per core configuration, the ecs.r9i.4xlarge offers predictable compute performance. This hardware profile is designed for memory-intensive workloads, including database hosting, in-memory caching, and enterprise application deployments that require substantial memory capacity and stable processing power without GPU acceleration.
