Adopt Pay-as-you-go pricing exclusively for all workloads to leverage maximum flexibility without any upfront financial commitments, ignoring potential cost savings on predictable workloads.

Implement Reserved Instances for the predictable, long-term workloads to capitalize on significant cost reductions, and use Pay-as-you-go for the variable workloads to maintain necessary flexibility.

Opt for Spot Instances across all workloads to achieve the lowest possible costs, without considering the specific nature or requirements of each workload, potentially risking operational stability.

Combine Reserved Instances for the predictable, long-term workloads to secure cost savings and Spot Instances for the fault-tolerant, flexible workloads to further reduce expenses, ensuring a balanced approach to cost management and operational efficiency.

Use Pay-as-you-go for all workloads to ensure maximum flexibility and avoid any upfront commitments, while accepting higher costs for predictable workloads.
