Spot Instance pricing history - Amazon Elastic Compute Cloud

Spot Instance pricing history

Spot Instance prices are set by Amazon EC2 and adjust gradually based on long-term trends in supply and demand for Spot Instance capacity.

When you request Spot Instances, we recommend that you use the default maximum price (the On-Demand price). When your request is fulfilled, your Spot Instances launch at the current Spot price, not exceeding the On-Demand price. If you want to specify a maximum price, we recommend that you first review the Spot price history. You can view the Spot price history for the last 90 days, filtering by instance type, operating system, and Availability Zone.

To view the current Spot prices

For the current Spot Instance prices, see Amazon EC2 Spot Instances Pricing.
