n4a-highmem-64 by Google Cloud Platform

A memory-optimized x86_64 server configuration featuring sixty-four dedicated virtual cores and five hundred twelve gigabytes of system memory.

Google Cloud Platform n4a-highmem-64 is an x86_64 architecture server instance within the n4a family, configured with 64 dedicated vCPUs and 512.0 GB of RAM. This resource distribution yields a memory-to-core ratio of 8.0 GB per vCPU, positioning the instance for memory-intensive applications. The server does not include local storage or integrated graphics processing units, meaning all storage needs must be handled via network-attached volumes. Additionally, no complimentary public IPv4 addresses are provided with this instance. The high memory density makes this configuration qualitatively cost-efficient for workloads that require substantial memory capacity without the added cost of local NVMe drives or GPU accelerators. It is suitable for hosting in-memory databases, large-scale data analytics, enterprise resource planning systems, and memory-heavy caching layers.
