To get started, visit the Spot Bid Advisor and select an AWS region, Operating System (OS), and bid price (choose 25%, 50%, or 100% of the current On-Demand price). The Spot Bid Advisor will analyze the Spot price history for matching instance types over the past week and month, and show you how often your selected bid price did not clear the Spot price. A higher frequency indicates a higher likelihood you would have been outbid during that time. Therefore, the lower your frequency of being outbid, the longer your Spot instances are likely to run without interruption.
