Difficulty: EasyEstimating GCP Costs with the Pricing Calculator

An architect is configuring an estimate in the Google Cloud Pricing Calculator for a fault-tolerant, stateless processing workload on Compute Engine that can handle unexpected instance termination. Which VM provisioning model should be selected in the calculator to achieve the maximum cost savings?

  1. Spot VMsAnswer
  2. B
    Standard VMs relying on automatic Sustained Use Discounts
  3. C
    Standard GKE Autopilot cluster node provisioning
  4. D
    Cloud Run instances configured with minimum instances set to active

Answer

Spot VMs should be selected in the Pricing Calculator to achieve maximum cost savings for fault-tolerant workloads.
Selecting Spot VMs in the Google Cloud Pricing Calculator is correct because Google Cloud offers massive discounts (up to 60-91%) on unused compute capacity for fault-tolerant, stateless workloads that can survive unexpected instance terminations.

Step-by-Step Solution

1
Identify the workload characteristics described in the scenario
The workload is stateless, fault-tolerant, and capable of handling sudden instance termination.
Fault-tolerant workloads can safely run on preemptible capacity without causing application failure.
2
Evaluate Compute Engine pricing models in the Google Cloud Pricing Calculator
Spot VMs offer discount rates between 60% and 91% compared to standard hourly on-demand rates.
Google Cloud offers excess compute capacity at deep discounts via Spot VMs for workloads that tolerate preemption.

Key Concept

Selecting Spot VMs for fault-tolerant workloads in the GCP Pricing Calculator to minimize compute costs.
