ecs.hfc9i.3xlarge by Alibaba Cloud

A compute-optimized instance featuring dedicated high-frequency Intel Xeon cores and a balanced network interface for CPU-intensive workloads.

Alibaba Cloud ecs.hfc9i.3xlarge is an x86_64 compute-optimized server instance running on the KVM hypervisor. It is powered by an Intel Xeon 6982P-C processor operating at 3.4 GHz, featuring 12 dedicated physical cores and 12 vCPUs with a 1.0 thread-per-core ratio. The system is equipped with 24.0 GB of RAM, providing a 1:2 memory-to-CPU ratio of 2.0 GB per core. It does not include local storage, relying entirely on external storage solutions, and provides a baseline network bandwidth of 10 Gbps. The dedicated core allocation ensures consistent, predictable CPU performance without hyperthreading contention. This configuration is qualitatively cost-efficient for compute-heavy workloads that do not require large memory capacities or local disk space. It is suited for batch processing, compute-intensive application servers, and high-performance computing tasks.
