December 4, 2023 - If you log into the console and look into the live Spot prices you can see that the lowest price for that instance is the same [minus some rounding] of the current price . On the other hand, the AWS Pricing calculator is using the "historical average discount for inf1.xlarge" and it is listed as 89% of OD. The price that it is quoted in the AWS Pricing Calculator is the OD price [ 0.274/Hour] over which it later applies the discount when calculating the monthly ...

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.
How can I reduce my cost here? Do I work locally?

r/aws on Reddit: Using EC2 instances at Spot pricing, but setting maximum price to the On-Demand price?
July 28, 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.

Spot Instance Pricing: How To Maximize Cost Savings - Cast AI
April 25, 2025 - When GCP launched the c3 instance types earlier this year, Cast AI automatically started provisioning these highly performant, low-cost Spot Instances. Users didn’t have to enroll for these new instance types; they became available to them by default. One customer saved an additional 12.5% month-over-month from February to March purely because CAST AI used the c3 instance type where applicable. Regarding Spot Instances, choosing the right generation of compute VMs is not a one-time decision. A closer look at the price evolution of m5a, m6a, and m7a instances shows how quickly things can change.
