To minimize costs while moving from EC2 instances to AWS Fargate, Compute Savings Plans are the most flexible and cost-effective option. Compute Savings Plans apply to a variety of compute services including AWS Fargate, Amazon EC2, and AWS Lambda, allowing for greater flexibility in managing costs as the company transitions to using only Fargate.

Compute Savings Plans:

Savings Plans provide significant savings over On-Demand pricing, up to 66% savings.

Compute Savings Plans offer the flexibility to move across instance types, AWS Regions, and operating systems.

Payment Options:

The No Upfront payment option provides the most flexibility and avoids large upfront capital expenditures.

The Partial Upfront payment option offers more savings but requires an initial payment.

1-Year Term:

A 1-year term is suitable for the company's 6-month transition period, allowing for cost savings without a long-term commitment.
