The answer is Compute Savings Plans. This is the correct choice because it allows you to commit to a consistent amount of compute usage measured in dollars per hour for a 1 or 3-year term, earning significant discounts of up to 66% without locking you into specific instance families, instance types, or even regions. The key technical distinction from Reserved Instances is this flexibility: Compute Savings Plans automatically apply your discount to any eligible EC2, Fargate, or Lambda usage, making it ideal for dynamic or evolving workloads. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of the core difference between commitment models—specifically that Reserved Instances lock you to an instance family, while Compute Savings Plans offer flexibility across instance families. A common trap is choosing Reserved Instances when the question emphasizes “no lock-in to instance type.” For a memory tip, think “Compute = Change” — if the workload might change families or regions, choose Compute Savings Plans.

Correct answer & explanation
✓
Compute Savings Plans
Compute Savings Plans offer the flexibility to commit to a consistent amount of compute usage (measured in $/hour) for a 1- or 3-year term, providing significant discounts (up to 66%) without requiring you to lock into specific instance types, families, or regions. This model automatically applies the discount to any EC2 instance, Fargate, or Lambda usage within the committed compute commitment, making it the correct answer.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Standard Reserved Instances
Why it's wrong here
Standard RIs are locked to specific instance types and regions, not flexible across instance families.
✗
Spot Instances
Why it's wrong here
Spot Instances do not involve term commitments; they can be interrupted at any time.
✓
Compute Savings Plans
Why this is correct
Compute Savings Plans offer flexible discounts across any EC2 instance in exchange for a consistent $/hour commitment.

✗
Convertible Reserved Instances
Why it's wrong here
Convertible RIs allow attribute changes but are still locked to EC2 and offer less flexibility than Savings Plans.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Compute Savings Plans with Reserved Instances, assuming that any long-term commitment must lock you to a specific instance type, but Compute Savings Plans specifically decouple the commitment from instance type details.
Detailed technical explanation
How to think about this question
Compute Savings Plans are a flexible pricing model that applies to EC2, Fargate, and Lambda usage, automatically discounting any instance type or region as long as the hourly compute commitment (in $/hour) is met. Under the hood, AWS tracks your compute usage across these services and applies the discounted rate to the first $X/hour of usage, with any overage billed at On-Demand rates. A real-world scenario: a company running a mix of EC2 instances (e.g., t3.medium for web servers and c5.large for batch processing) can use a Compute Savings Plan to cover both without needing separate reservations for each instance type.

Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Variation 1. A company runs a containerized application on Amazon ECS using a mix of Amazon EC2 On-Demand instances from different instance families (e.g., M5, C5, R5). The workload is consistent, and the company is willing to commit to a 1-year term to reduce costs. However, the team expects to change instance families within the next 12 months due to new hardware requirements and wants the flexibility to switch instance families without incurring a financial penalty. Which pricing option best meets these requirements?
medium
✓ A.Compute Savings Plans
B.EC2 Instance Savings Plans
C.Convertible Reserved Instances
D.Standard Reserved Instances
Why A: Compute Savings Plans provide the most flexibility by applying a discounted hourly commitment (e.g., $10/hour) across any EC2 instance family, region, OS, or tenancy, and also cover Fargate and Lambda usage. Since the company expects to change instance families within the 1-year term, Compute Savings Plans allow switching without penalty, unlike instance-specific plans.
Variation 2. A company runs a set of steady-state workloads on Amazon EC2 instances and Amazon ECS Fargate tasks. The company expects consistent usage for the next 3 years and wants to reduce compute costs. The company prefers flexibility to move workloads between different instance families and across different AWS compute services (EC2, ECS, and Lambda) without committing to a specific instance type or family. Which AWS pricing model meets these requirements?
C.Standard Reserved Instances (1-year, all upfront)
D.Convertible Reserved Instances (3-year, all upfront)
Why A: Compute Savings Plans (3-year, partial upfront) is correct because it provides the highest flexibility, allowing workloads to move between EC2 instances, ECS Fargate, and Lambda without committing to a specific instance family or compute service. The 3-year term with partial upfront offers the maximum discount (up to 66%) for steady-state workloads while still enabling the required flexibility across compute services. This pricing model automatically applies the lowest price across any region and compute option, making it ideal for the described steady-state but flexible workload.
