What is the key advantage of Spot Instances?

Guaranteed cost for a fixed period
Lower bidding prices for unused resources
Permanent access to resources
Reservation without payment

The correct answer is: Lower bidding prices for unused resources

The key advantage of Spot Instances is that they allow users to bid on unused EC2 capacity, often at significantly lower prices compared to On-Demand Instances. This is particularly beneficial for workloads that are flexible and can tolerate interruptions since Spot Instances can be reclaimed by AWS with little notice when demand for resources increases. By utilizing Spot Instances, organizations can reduce their compute costs substantially, taking advantage of the price fluctuations in the AWS market for spare capacity. This makes them a cost-effective option for tasks such as batch processing, data analysis, and other applications that do not require permanent access to instances.
