Server Description
An x86_64 memory-optimized instance featuring dedicated Intel processors, high memory density, and optimized network performance for memory-intensive enterprise workloads.
Amazon Web Services r8in.4xlarge is an x86_64 memory-optimized instance featuring 16 dedicated vCPUs and 128.0 GB of RAM. Powered by an Intel processor running at 3.9 GHz, this instance utilizes the AWS Nitro hypervisor to deliver dedicated compute resources with 8 physical cores and 2 threads per core. The instance lacks local storage and GPU accelerators, relying entirely on network-attached storage. It provides a baseline network bandwidth of 25 Gbps, optimized for network and EBS performance. With a high memory-to-vCPU ratio of 8.0 GB per core, the r8in.4xlarge is structured for memory-intensive workloads. It is qualitatively cost-efficient for applications requiring significant memory capacity without the overhead of local physical disks. Suitable workloads include in-memory databases, caching systems, and enterprise applications.
