Zorluk: ZorEstimating GCP Costs with the Pricing Calculator

A lead cloud architect is using the Google Cloud Pricing Calculator to model monthly infrastructure costs for an enterprise telemetry platform. The design incorporates continuous 24/7 Compute Engine virtual machines for core data ingestion and transient Compute Engine Spot VMs for batch analytics processing. The engineering team requires an accurate cost estimate that properly accounts for Google Cloud billing discount mechanics. Which statement correctly describes how the Google Cloud Pricing Calculator applies discounts when estimating costs for these Compute Engine workloads?

  1. The calculator automatically applies Sustained Use Discounts (SUDs) to eligible continuously running standard Compute Engine instances based on monthly runtime, whereas Spot VMs receive separate deeply discounted fixed pricing and do not qualify for SUDs.Cevap
  2. B
    The calculator automatically applies 1-year Committed Use Discounts (CUDs) to standard Compute Engine instances whenever their estimated monthly runtime reaches 730 hours without requiring an explicit commitment contract.
  3. C
    The calculator allows Sustained Use Discounts (SUDs) to be stacked on top of Spot VM rates whenever Spot instances remain active for more than 25% of the billing cycle.
  4. D
    The calculator applies serverless request-based pricing models to Compute Engine instances if the instances are configured using container-optimized operating system images.

Cevap

The Google Cloud Pricing Calculator automatically includes Sustained Use Discounts (SUDs) for eligible standard Compute Engine instances running continuously, while Spot VMs receive separate fixed discount pricing and are ineligible for SUDs.
The option stating that the calculator automatically applies Sustained Use Discounts to eligible continuous standard Compute Engine instances based on monthly runtime, while Spot VMs receive separate fixed discount pricing and do not qualify for SUDs, is correct. In Google Cloud, SUDs automatically kick in when standard VM instances run for more than 25% of a billing month. Spot VMs offer fixed upfront discounts for preemptible workloads and are explicitly excluded from receiving SUDs.

Adım Adım Çözüm

1
Analyze Compute Engine discount types in Google Cloud billing.
Sustained Use Discounts (SUDs) automatically reduce the hourly rate for vCPU and memory on standard VM instances running more than 25% of a billing month.
SUDs require no prior commitment and are calculated automatically based on continuous monthly usage.
2
Evaluate Spot VM pricing mechanisms in the Google Cloud Pricing Calculator.
Spot VMs are priced at a fixed, deeply discounted rate (typically 60-90% off standard pricing) due to preemptibility.
Because Spot VMs already receive maximal discounting, they do not qualify for additional Sustained Use Discounts or Committed Use Discounts.
3
Distinguish Committed Use Discounts (CUDs) from Sustained Use Discounts (SUDs).
CUDs offer high savings but require selecting a explicit 1-year or 3-year commitment term in the calculator, whereas SUDs occur automatically.
Running a standard VM for 730 hours defaults to SUD application unless a formal CUD option is explicitly selected.
