When to choose it
Pick AWS r5.4xlarge when you are already invested in the AWS ecosystem — existing VPC/networking, IAM, managed services, and team expertise usually outweigh the $123.74/mo gap to the cheapest equivalent (GCP n2-highmem-16). Cross-provider migration rarely pays for itself on single-instance compute pricing alone.
This is an on-demand, single-instance list price. Reserved and committed-use discounts (up to ~72%) and your real utilization pattern will move the numbers — model your whole stack with the cloud cost calculator before committing.
