EC2 Spot Instances

EC2 Spot Instances are a way to rent computing power from Amazon at significantly lower prices by bidding on unused capacity in their data centers. They are ideal for flexible, non-urgent tasks, as they can be interrupted when the capacity is needed elsewhere or if the market price exceeds your bid. This approach allows for cost-effective scaling of workloads, especially for tasks like batch processing, data analysis, or testing, where occasional interruptions won't impact overall results. Essentially, Spot Instances offer affordable compute resources with the understanding that they may not always be guaranteed to run continuously.
