Question
A company wants to run a batch processing application that can handle interruptions. The application can run on 500 Amazon EC2 instances during peak processing times. The application can use various instance types, but the instances must meet minimum memory requirements. The application must remain highly available. Which solution will meet these requirements MOST cost-effectively?
Options
- ALaunch an EC2 Fleet of Spot Instances that includes multiple instance types across multiple
- BLaunch 250 EC2 On-Demand Instances and 250 Reserved Instances across multiple Availability
- CLaunch an EC2 Fleet of Spot Instances that includes one instance type in a single Availability
- DLaunch 500 EC2 On-Demand Instances. Purchase a 1-year Savings Plan. Implement Auto

Explanation
Using Spot Instances is the most cost-effective choice for interruption-tolerant batch workloads. An EC2 Fleet that spans multiple instance types and multiple Availability Zones can satisfy the minimum memory requirement while improving availability and lowering the risk of capacity shortfalls. The capacity-optimized allocation strategy further reduces interruption risk by selecting Spot capacity with the most available headroom, helping the fleet maintain the required scale.
