AWS Certified Solutions Architect Professional SAP-C02 Practice Question

A large enterprise runs a diverse set of workloads on AWS across multiple accounts within an AWS Organization. Their aggregate compute usage, primarily from EC2 instances of various families and some AWS Fargate tasks, is consistently around $50 per hour. While the overall usage is stable, the specific instance families and services used within individual accounts fluctuate as development teams modernize their applications. The company previously used a mix of Standard and Convertible Reserved Instances but found the management overhead of exchanges and capacity reservations cumbersome. They are seeking a solution that maximizes cost savings with a 1-year commitment, provides flexibility across instance families and compute services, and minimizes administrative effort.

Which AWS pricing model strategy would be the most cost-effective and flexible for this scenario?

  • Purchase a 1-year, All Upfront Compute Savings Plan that covers their baseline usage of $50/hour. This provides a high discount and automatically applies to their EC2 and Fargate usage across the organization, regardless of instance family or region changes.

  • Purchase 1-year EC2 Instance Savings Plans for each specific instance family and region where they have stable usage. This would offer a slightly higher discount for those specific families but would not cover Fargate or adapt to changes in instance family choices.

  • Transition the baseline workloads to run on EC2 Spot Instances, using a Spot Fleet to bid on capacity across various instance types to achieve the lowest possible cost.

  • Continue to use and purchase 1-year Convertible Reserved Instances for the most common instance families. Periodically perform exchanges to adapt to the changing application needs.
