Zorluk: KolayReserved Instances and Savings Plans Optimization

A SysOps team is tasked with reducing compute costs for a new serverless application. The application's architecture includes a mix of Amazon EC2 instances, AWS Fargate containers, and AWS Lambda functions across several AWS Regions. Which commitment-based pricing model should the SysOps team select to optimize costs with the greatest flexibility?

  1. A
    Convertible Reserved Instances
  2. B
    EC2 Instance Savings Plans
  3. Compute Savings PlansCevap
  4. D
    Standard Reserved Instances

Cevap

Compute Savings Plans are the most appropriate choice because they automatically apply to compute usage across Amazon EC2, AWS Fargate, and AWS Lambda, providing the maximum flexibility for the multi-service architecture.
Compute Savings Plans offer the greatest flexibility and automatically apply to compute usage across Amazon EC2, AWS Fargate, and AWS Lambda, regardless of region, instance family, size, operating system, or tenancy.

Adım Adım Çözüm

1
Identify the compute resources in scope for cost optimization.
The architecture consists of EC2 instances, AWS Fargate containers, and AWS Lambda functions.
Understanding the resource types is necessary to select a pricing model that covers all of them.
2
Evaluate the coverage of available savings models.
Compute Savings Plans apply to EC2, Fargate, and Lambda. EC2 Instance Savings Plans and Reserved Instances (Convertible or Standard) apply only to EC2 instances.
Comparing coverage boundaries helps identify which models can apply to all the targeted resources.
3
Determine the pricing model that offers the greatest flexibility for this multi-service deployment.
Compute Savings Plans are selected.
They automatically apply to all three compute services across different regions and configurations without manual modification.

Anahtar Kavram

Compute Savings Plans automatically apply to EC2, Fargate, and Lambda usage across any AWS Region and configuration, making them the most flexible commitment option.
