Server Description
An Arm64 memory-optimized instance featuring sixteen dedicated cores and a high memory-to-vCPU ratio for memory-intensive workloads.
Amazon Web Services r9g.4xlarge is an Arm64 memory-optimized server instance powered by AWS Graviton processors running at 3.3 GHz. It features 16 dedicated physical cores and 16 vCPUs with a single thread per core, supported by 128.0 GB of system memory. This configuration provides a resource density of 8.0 GB of RAM per core. Operating on the AWS Nitro hypervisor, the instance delivers a baseline network bandwidth of 8 Gbps. It does not include local storage or integrated GPUs, requiring network-attached storage for data persistence. The Arm64 architecture offers qualitative cost efficiency through high resource density and power-efficient compute. This instance is designed for memory-intensive workloads, including in-memory databases, caching layers, and data processing applications that require substantial memory capacity relative to CPU resources.
