Server Description
A compute-optimized virtual instance featuring dedicated high-frequency Intel processors and high-speed networking for intensive processing workloads.
Amazon Web Services c8ib.12xlarge is a compute-optimized instance designed for high-performance workloads. Powered by an Intel x86_64 processor running at 3.9 GHz, it delivers 48 vCPUs across 24 dedicated physical cores, paired with 96.0 GB of system memory. Built on the AWS Nitro hypervisor, the instance ensures minimal virtualization overhead. It features a baseline network bandwidth of 50 Gbps but does not include local storage or GPU accelerators, requiring external network-attached storage for data persistence. This hardware profile offers a qualitative cost-efficiency advantage for compute-heavy tasks that do not demand large memory capacities or local disk I/O. The c8ib.12xlarge is suited for batch processing, high-performance computing, distributed analytics, and compute-intensive web serving.
