A company manages a multi-account AWS environment using AWS Organizations with consolidated billing enabled.

* Member Account A runs a steady-state workload on Amazon EC2 $c5.large$ instances in the $us-east-1$ Region. This workload is expected to remain unchanged for the next $12$ months.
* Member Account B runs a containerized microservices application on AWS Fargate in the $us-east-1$ Region and utilizes several AWS Lambda functions for data processing. Within the next $3$ months, the company plans to migrate the Fargate application to the $us-west-2$ Region and upgrade the container configurations.

A SysOps administrator must recommend a $1$ -year cost optimization strategy that maximizes savings for these workloads while accommodating the planned migration.

Which two commitment strategies should the administrator recommend? (Select TWO.)

Purchase a $1$ -year Compute Savings Plan to cover the AWS Fargate and AWS Lambda workloads.Answer
Purchase a $1$ -year EC2 Instance Savings Plan for the $c5$ instance family in $us-east-1$ to cover the EC2 instances in Member Account A.Answer
C
Purchase a $1$ -year EC2 Instance Savings Plan for the $c5$ instance family in $us-east-1$ to cover both the EC2 instances and the AWS Fargate tasks.
D
Purchase a $1$ -year Compute Savings Plan for the Fargate tasks and AWS Lambda, and disable Savings Plan sharing at the organization's payer account level.
E
Purchase $1$ -year Convertible Reserved Instances in $us-east-1$ to cover the AWS Fargate tasks to allow for the future region modification.

Answer

The SysOps administrator should recommend purchasing a 1-year Compute Savings Plan to cover the AWS Fargate and AWS Lambda workloads, and a 1-year EC2 Instance Savings Plan for the c5 instance family in us-east-1 to cover the EC2 instances.

The correct strategy combines an EC2 Instance Savings Plan for the stable c5 EC2 instances (maximizing the discount to up to 72% for those specific instances) with a Compute Savings Plan for the Fargate and Lambda workloads (providing the flexibility to apply discounts across regions and serverless configurations as the application migrates).

Step-by-Step Solution

Analyze the workload requirements for Member Account A.

Member Account A has EC2 c5.large instances in us-east-1 running steady-state for 12 months. Since the family and region are fixed, an EC2 Instance Savings Plan provides the highest savings (up to 72%) while allowing size changes within the c5 family.

Choosing the most specific plan type for stable workloads maximizes cost savings.

Analyze the workload requirements for Member Account B.

Member Account B uses AWS Fargate and AWS Lambda, and plans to migrate Fargate from us-east-1 to us-west-2 with configuration changes. Compute Savings Plans are required here because they are the only Savings Plans that apply to Fargate and Lambda, and they automatically apply across regions and instance changes.

Compute Savings Plans provide the necessary flexibility for serverless workloads and regional migrations.

Evaluate the administrative sharing settings.

Ensure Savings Plan sharing remains enabled at the AWS Organizations payer level so that any unutilized commitment can benefit other accounts in the organization.

Disabling sharing is sub-optimal and reduces the flexibility of the organization's total commitment.

Key Concept

Selecting the optimal combination of Compute Savings Plans and EC2 Instance Savings Plans based on workload stability, region flexibility, and service type (EC2 vs. Fargate/Lambda).
