A “Spot Instance” is a cost-saving opportunity that allows you to secure unused computing capacity at lower prices due to its bidding-based pricing system. However, it may experience temporary work interruptions when demand is highest.
In contrast, On-Demand Instances offer a stable and uninterrupted service at a higher fixed rate.
Spot Instances are best suited for cost-sensitive and flexible tasks that can handle potential interruptions, while On-Demand Instances are more appropriate for tasks that require reliable and uninterrupted performance. Users should choose the option that best fits their budget constraints and tolerance for potential interruptions.
The cost of a Spot Instance is USD 0.25 per core hour, and the cost of an On-Demand Instance is USD 0.50 per core hour.
