Which one should you pick?
Since AWS r5.xlarge and Azure Standard_E4s_v5 are priced identically at this spec tier, price should not be the deciding factor. Pick AWS r5.xlarge if you're already building on AWS — existing networking, IAM, and tooling outweigh a tie on list price.
Pick Azure Standard_E4s_v5 if Azure is your existing ecosystem instead, or if you value a specific managed service, region footprint, or support plan that AWS doesn't offer.
Either way, this is a single-instance, on-demand comparison. Reserved/committed-use discounts (up to ~72% on both platforms) and your actual utilization pattern will move the real numbers — model your full workload with the calculator before deciding.
