Which solution will meet these requirements?
Launch the Spot Instances up to the maximum capacity of the Auto Scaling group.
Launch the Spot Instances by using the diversified strategy.
Launch the Spot Instances by using the capacity optimized strategy.
Use the Spot Instance advisor to help determine the best Spot allocation strategy.
Explanations:
Launching Spot Instances up to the maximum capacity of the Auto Scaling group does not consider instance availability. It may lead to interruptions due to insufficient availability in the chosen instance pools.
The diversified strategy distributes Spot Instances across different instance types and Availability Zones, but it does not specifically optimize for instance availability, which is the primary goal in this scenario.
The capacity optimized strategy selects Spot Instance pools that have the most available capacity for the requested instances, making it the ideal choice for ensuring maximum availability and fewer interruptions.
The Spot Instance advisor provides guidance on instance pricing and availability, but it does not automatically help in selecting a strategy. The capacity optimized strategy is the better option for provisioning a fleet with high availability.
I gauge that the answer is:
Launch the Spot Instances by using the capacity optimized strategy.
In my opinion, the answer is:
Launch the Spot Instances by using the capacity optimized strategy.
