r/aws on Reddit: Do people actually use Amazon EC2 Spot?
June 24, 2023 -
I'm curious on how much our team should be leveraging this for cost savings. If you don't use Spot, why aren't you using it? For us, it's because we don't really know how to use it but curious to know others' thoughts.

What are spot instances in AWS?
May 7, 2024 - Spot Instances provide users with access to spare compute capacity in the cloud at greatly reduced prices compared to standard on-demand instances. Users bid on this unused capacity, specifying the maximum price they are willing to pay per hour.

Actually there are three allocation types:
on demand - kind of "default" mode. You request an instance, if there is free capacity, you will get the instance. No long term commitment, but once you get an instance, it's yours. It may happen that you will get a message that there is no free capacity for the specific instance type and AZ (so far it happened to me only once with AWS).
reserved - AWS reserves the capacity for you. You have guarantee that you will get the instance type in the selected region or AZ.
spot instance - it's kind of auction / bidding of unused capacity. You ask for an instance, you provide your maximum price and if there is free capacity and your price is at the current price or higher, you will get an instance. The difference is - if the free capacity is exhausted, or the current price is higher than your maximum bid price, your spot instance is terminated . You can get a termination warning event upfront.

The resources for both are the same, spot instances utilise the spare compute capacity within the AWS availability zone (those that are not reserved or launched on-demand).
Depending on the demand for that instance class in the availability zone the spot price will increase or decrease (even surpassing the on-demand price).
When you use a spot instance you are taking a risk that if demand increases you will lose access to the spot instance (you are given a 2 minute warning before termination). For his reason it is common to use a mixture of on-demand/reserved instances and spot instances so that you can withstand instance terminations.
Commonly in EC2 applications you would use an autoscaling group with a configured proportion between on-demand/reserved nodes and spot instances.
For more information take a look at the Requesting Spot Instances for fault-tolerant and flexible applications documentation.

What are AWS spot instances?
December 13, 2022 - AWS spot instances represent AWS’s excess capacity. As a cloud provider, they must have spare capacity available for any surge in customer demand. To offset the loss of idle infrastructure, AWS offers this excess capacity at a massive discount to drive usage.

Spot Instances Explained: How They Can Lower Cloud Costs
July 9, 2024 - You can utilize this capacity at a steeply discounted rate. Amazon will enable them to help EC2 users cut cloud computing costs by using idle EC2 capacity instead of relying only on costlier On-Demand Instances. What you pay in return is known as a Spot Price, and it’s charged hourly for each Spot Instance.
