Compute Savings Plan offers the flexibility to use compute services across different instance families, regions, and even between EC2 and Fargate. It provides cost savings based on your commitment to a consistent amount of usage (measured in $/hour) over a 1- or 3-year term. However, it doesn't offer the upfront payment option that the company is looking for. Convertible Reserved Instances, on the other hand, allow the company to make upfront payments and still offer flexibility to change instance types, operating systems, or tenancies during the term, which aligns with the company's future plans to migrate to a serverless architecture. Both options provide cost savings, but the upfront payment feature and flexibility of Convertible Reserved Instances make them a better fit for this particular scenario.

The best option for optimizing the company's costs is Convertible Reserved Instances. This allows the company to pay for resources up front and provides the flexibility to change instance types, which is beneficial for a partial migration to a serverless architecture in the future.

Compute Savings Plans provide the most flexibility and prices that are up to 66 percent off of On-Demand rates. These plans automatically apply to your EC2 instance usage, regardless of instance family (for example, m5, c5, etc.), instance sizes (for example, c5.large, c5.xlarge, etc.), Region (for example, us-east-1, us-east-2, etc.), operating system (for example, Windows, Linux, etc.), or tenancy (for example, Dedicated, default, Dedicated Host) https://docs.aws.amazon.com/savingsplans/latest/userguide/what-is-savings-plans.html#plan-types

Compute Savings Plans provide the most flexibility and help to reduce your costs by up to 66%. These plans automatically apply to EC2 instance usage regardless of instance family, size, AZ, Region, OS or tenancy, and also apply to Fargate or Lambda usage. For example, with Compute Savings Plans, you can change from C4 to M5 instances, shift a workload from EU (Ireland) to EU (London), or move a workload from EC2 to Fargate or Lambda at any time and automatically continue to pay the Savings Plans price. https://aws.amazon.com/savingsplans/compute-pricing/

Compute Savings Plans for Amazon EC2 - No UpFront

Compute Savings Plans are designed to provide cost savings for Amazon EC2 instances, regardless of the instance family, size, region, or operating system. They offer flexibility and coverage for a one- or three-year commitment, allowing you to reserve compute capacity in exchange for a lower hourly rate.

Compute Savings plan is correct answer because it lets you switch between EC2 and serverless services like Fargate and Lambda.

For the company's scenario, where they currently have applications running on Amazon EC2 instances but plan to partially migrate to a serverless architecture in the future, the optimal AWS purchasing option to optimize costs is EC2 Instance Savings Plans. EC2 Instance Savings Plans allow the company to pay upfront for specific instance types and regions for either a one- or three-year term. By committing to these savings plans, the company can benefit from discounted hourly rates for their EC2 instances, resulting in cost savings compared to On-Demand pricing.

The AWS purchasing option that will optimize the company’s costs is EC2 Instance Savings Plans. EC2 Instance Savings Plans provide the most flexibility and help reduce costs by up to 72% compared to On-Demand pricing1. Savings Plans are a flexible pricing model that offer low prices on EC2 instances usage in exchange for a commitment to a consistent amount of usage (measured in dollars per hour) for a term of 1 or 3 years1.

Compute Savings Plans, you can move a workload from EC2 to Fargate or Lambda at any time and automatically continue to pay the Savings Plans price.
