ecs.c9i.4xlarge by Alibaba Cloud

A dedicated compute-optimized instance featuring sixteen physical Intel Xeon cores and a balanced memory-to-CPU ratio for predictable processing workloads.

Alibaba Cloud ecs.c9i.4xlarge is a compute-optimized virtual machine instance featuring 16 dedicated physical cores powered by an Intel Xeon 6982P-C processor running at 3.2 GHz. Built on the x86_64 architecture and utilizing the KVM hypervisor, this instance provides a single thread per core to eliminate hyperthreading resource contention. It is equipped with 32.0 GB of system memory, offering a 2.0 GB per core ratio, and features a baseline network bandwidth of 12 Gbps. The instance does not include local storage or GPU hardware, relying on external network-attached storage. This hardware profile is qualitatively cost-efficient for compute-heavy workloads that require predictable CPU performance without massive memory overhead, making it suitable for batch processing, web serving, and computational tasks.
