Server Description
A compute-optimized instance featuring forty-eight dedicated Intel Xeon cores and twenty-five gigabits per second network bandwidth for compute-heavy workloads.
Alibaba Cloud ecs.c8i.12xlarge is a compute-optimized instance built on the x86_64 architecture and managed via the KVM hypervisor. It features 48 dedicated vCPUs powered by Intel Xeon 8475B processors running at 2.7 GHz, paired with 96.0 GB of system memory. This configuration provides a 1:2 vCPU-to-RAM ratio, allocating 2.0 GB of memory per core. The instance does not include local storage or GPU hardware, relying on network-attached storage for data persistence. It delivers a baseline network bandwidth of 25 Gbps. Designed for compute-heavy tasks, the ecs.c8i.12xlarge is structured for workloads such as batch processing, web serving, and compilation pipelines where dedicated CPU performance is prioritized over large memory allocations or local storage.
