Zorluk: KolayOptimizing Resource Costs and Sizing

A company runs production workloads across two AWS accounts that belong to an organization in AWS Organizations. Account A runs microservices hosted on AWS Fargate. Account B runs legacy processing applications on Amazon EC2 instances. The company wants to reduce compute costs by committing to a 1-year Savings Plan. The solution must provide maximum savings coverage across both workloads, maintain high availability, and require minimal administrative effort. Which of the following actions should a Solutions Architect recommend to meet these requirements? (Select TWO.)

  1. Purchase a Compute Savings Plan in the organization's management account.Cevap
  2. Ensure that Savings Plan discount sharing is enabled in the Consolidated Billing settings for the organization.Cevap
  3. C
    Purchase an EC2 Instance Savings Plan in the management account to cover both the EC2 instances and the Fargate tasks.
  4. D
    Use AWS Resource Access Manager (RAM) to share the purchased Savings Plan with the member accounts.
  5. E
    Consolidate all outbound internet traffic from both accounts through a single NAT Gateway in a single Availability Zone to minimize hourly gateway fees.

Cevap

To optimize costs while maintaining flexibility and high availability, purchase a Compute Savings Plan in the organization's management account and verify that Savings Plan discount sharing is enabled in the Consolidated Billing configurations.
Purchasing a Compute Savings Plan in the management account provides maximum flexibility as it covers both Amazon EC2 and AWS Fargate usage. Ensuring that discount sharing is enabled in Consolidated Billing allows these savings to apply automatically to workloads in both member accounts without any manual allocation or administration.

Adım Adım Çözüm

1
Determine the resource types in scope for cost optimization.
The architecture uses both Amazon EC2 instances and AWS Fargate tasks across multiple accounts.
Understanding the compute mix dictates which Savings Plan type will provide coverage.
2
Select the correct Savings Plan type.
Choose a Compute Savings Plan since it applies to both EC2 and AWS Fargate, unlike EC2 Instance Savings Plans which only apply to EC2.
Maximizing discount coverage requires a plan that spans across heterogeneous compute types.
3
Configure organization-wide sharing.
Enable Savings Plan discount sharing in the Consolidated Billing settings of the management account.
This allows the benefits of the Savings Plan purchased in the management account to flow automatically to the workloads in Account A and Account B.

Anahtar Kavram

Compute Savings Plans are the most flexible Savings Plan type as they automatically apply to EC2 and Fargate across any AWS Organization account when discount sharing is enabled.
