How Spot Instances Work - Overview of Amazon EC2 Spot Instances
You can optionally specify a maximum price for your Spot Instance. If you don't specify a maximum price, the maximum price defaults to the On-Demand price. Note that you never pay more than the Spot price that is in effect when your Spot Instance is running. We recommend that you do not specify a maximum price, but rather let the maximum price default to the On-Demand price.

Spot price per unit hour example - Amazon EC2 Auto Scaling
You can determine the price per unit hour by dividing your price for an instance type by the number of units that it represents. For On-Demand Instances, the price per unit hour is the same when deploying one instance type as it is when deploying a different size of the same instance type. In contrast, however, the Spot price per unit hour varies by Spot pool.

r/aws on Reddit: Using EC2 instances at Spot pricing, but setting maximum price to the On-Demand price?
August 1, 2020 -
Hey guys, I'm currently taking Cloud Guru's SAA course and just had a lecture on EC2 Spot Pricing.
I was just curious - let's say you want to provision some EC2 instances for a critical, uninterruptible workload, but don't want to reserve capacity but still want to save money. Could you not just deploy EC2 Spot instances, but just set the maximum price to the On-Demand price? I imagine the Spot price never jumps above the On-Demand price so the instances would never automatically terminate, and if you wanted to be super safe you could just add a Spot Block. This would result in what is effectively an On-Demand instance with a constant but variable discount, right? Are there any cons to doing this?

Aside from spot price jumping above the on demand price, which is possible, spot instances are also able to be terminated by AWS for capacity reasons.

There is no such thing as uniterruptable task, there are just tasks that are more PITA if they fail. AWS gives you 95% chances that your spot instance will survive a month while it's 99.99% for on-demand. So it's up to you whether the risk it worth it. Nonetheless you always have to plan against someone pulling a plug on your server.

Hi all I am working on some ML stuff, and was asked to use spot instances for all my work. I am not a cloud expert, so can’t optimise. But I found that I paid 3k for a day when I was working on some data analysis part.
