Availability & price by region
Spot is the 7-day average of the cheapest zone's spot price in each region, from the RunsOn finder: an estimate of an hour in your own AWS account, where RunsOn adds no markup. The bar shows how far it runs under on-demand; the badge is AWS's spot-interruption band for the type.

Spot is the cheapest availability zone's spot price at each of the RunsOn finder's fetches (every 90 minutes), averaged over 7 days; on-demand is the Linux list price. Savings compare the two. Prices fetched 14 Oct 2026. The interruption band is AWS Spot Advisor's, fetched 14 Oct 2026; it lists none for us-east-1, us-west-2, eu-west-1 and eu-central-1 (“n/a”). No finder price for eu-west-1: “—”.

About these benchmarks
The open benchmark harness launches r9g.large as a RunsOn runner and runs PassMark PerformanceTest (CPU Single
Threaded and CPU Mark), sysbench on one thread and on every thread, and 7-Zip's built-in benchmark. These numbers come from the
hardware suite, the suite that measured this type in the most runs; each is the value of its one job of the current
workload definition in the last 30 days.
A type takes a place once it has 3 runs. A type within 5% of the type heading its group shares that place (“joint #2”); a lead under 5% is no lead.
Prices come from the RunsOn finder for the four regions shown; savings compare its 7-day average spot price with the on-demand price. RunsOn launches this type the same way for any job: ephemeral EC2 in your account, one CloudFormation stack. More in the methodology.
Run r9g.large in your own account.
The benchmark runs on the same RunsOn anyone can deploy. One CloudFormation stack, your AWS account, ~10 minutes.
