Server Description
A memory-optimized, network-enhanced virtual server featuring high-frequency Intel processors and substantial RAM capacity for demanding enterprise database workloads.
Amazon Web Services r8in.12xlarge is a memory-optimized instance designed for high-throughput, memory-intensive workloads. Powered by the AWS Nitro hypervisor, it features an Intel x86_64 processor running at 3.9 GHz with 48 dedicated vCPUs and 24 physical cores. The instance is equipped with 384.0 GB of RAM, establishing an 8 GB per vCPU ratio. It lacks local storage, relying entirely on network-attached storage, but compensates with a high baseline network bandwidth of 75 Gbps. This network and EBS optimization makes it highly suitable for large-scale databases, in-memory caching, and enterprise applications. The hardware configuration offers a balanced tradeoff between high memory capacity and robust network performance, delivering qualitative cost efficiency for enterprise workloads that do not require local physical disks.
