Server Description
A memory-optimized instance combining dedicated local NVMe SSD storage with a high memory-to-vCPU ratio for budget-conscious, memory-bound workloads.
Amazon Web Services r5ad.large is a memory-optimized instance featuring an AMD EPYC 7571 processor with 2 vCPUs, 1 physical core, and 16.0 GB of DDR4 memory. Operating at 2.2 GHz, this x86_64 instance includes 75 GB of local NVMe SSD storage and a baseline network bandwidth of 1 Gbps under the Nitro hypervisor. Benchmark data indicates modest processing capabilities, with CPU and memory bandwidth tests generally ranking in the bottom 10% of performance, though encryption and memory scores reach the bottom 25%. With 8 GB of RAM per vCPU and dedicated local storage, the r5ad.large provides qualitative cost efficiency for memory-heavy workloads that do not demand high compute performance. It is suitable for small-scale databases, caching layers, and memory-intensive applications requiring local scratch space.
