Difficulty: MediumEstimating GCP Costs with the Pricing Calculator

A company is planning to run a continuous 24/7 video rendering service on Compute Engine virtual machines with predictable, steady resource utilization over the next three years. A cloud engineer needs to model the projected monthly infrastructure expenses in the Google Cloud Pricing Calculator. Which configuration option in the Google Cloud Pricing Calculator should the engineer select to produce the most accurate and cost-effective estimate for this continuous baseline workload?

  1. Apply a 3-Year Committed Use Discount (CUD) model to the Compute Engine instance specifications in the calculator.Answer
  2. B
    Rely on automatic Sustained Use Discounts (SUDs) without selecting any usage commitment model in the calculator.
  3. C
    Select the Spot VM option for all Compute Engine instances to simulate maximum cost reduction.
  4. D
    Configure attached persistent storage disks using the Cloud Storage Archive tier in the pricing calculator line item.

Answer

Apply a 3-Year Committed Use Discount (CUD) model to the Compute Engine instance specifications in the calculator.
For continuous, predictable workloads spanning multiple years, Google Cloud provides Committed Use Discounts (CUDs) for 1-year or 3-year terms. Applying a 3-Year Committed Use Discount in the Google Cloud Pricing Calculator yields the most accurate estimate and maximum cost efficiency for long-term baseline Compute Engine capacity.

Step-by-Step Solution

1
Analyze the workload characteristics provided in the scenario.
The workload runs continuous 24/7 processing with predictable baseline resource utilization over a 3-year horizon.
Identifying workload predictability and duration dictates which pricing model applies.
2
Evaluate pricing models supported by the Google Cloud Pricing Calculator for steady Compute Engine workloads.
Committed Use Discounts (CUDs) require a commitment of 1 or 3 years in exchange for deeply discounted hourly rates on vCPUs and RAM.
A 3-year commitment offers the highest cost savings for predictable, continuous compute capacity.
3
Select the option in the pricing calculator that models 3-Year CUDs.
Configuring a 3-Year Committed Use Discount line item yields the most accurate baseline cost projection.
This accurately reflects the planned architectural strategy and financial commitment.
