Explanation
Spot Instances are the most cost-effective option for this use case because:
-
Cost Savings: Spot Instances offer up to 90% discount compared to On-Demand Instances
-
Interruptible Workloads: The test workloads can be interrupted, which aligns perfectly with Spot Instances' nature (AWS can reclaim them with a 2-minute warning)
-
Flexible Timing: The workloads don't require specific start times, making them ideal for Spot Instances which are available when AWS has excess capacity
Why other options are less suitable:
-
On-Demand Instances: Most expensive option, best for workloads that need guaranteed availability
-
Reserved Instances: Require long-term commitment and are better for predictable, steady-state workloads
-
Dedicated Hosts: Most expensive option, designed for regulatory compliance or software licensing requirements
Spot Instances provide the optimal balance of cost-effectiveness and suitability for interruptible test workloads.
