A company will migrate workloads from EC2 to AWS Fargate and expects to stop using EC2 in 6 months. They have estimated their future Fargate spend and want to maximize discounts without ending up with unused reservations. Which purchase option best meets these constraints?

Compute Savings Plans offer the most flexibility, applying to Fargate, EC2, and Lambda usage, which is ideal for a migration scenario. A 1-year term aligns with the company's 6-month remaining EC2 usage and future Fargate plans, ensuring they don't commit to a longer term than necessary. Partial Upfront payment provides a better discount than No Upfront without the full commitment of All Upfront, balancing cost savings with financial flexibility. EC2 Instance Savings Plans and EC2 Reserved Instances are less suitable because they are specific to EC2 and would not apply to the future Fargate usage, leading to unused reservations after the migration.
