A cloud finance specialist is configuring an estimate in the Google Cloud Pricing Calculator for a batch data transformation job running on standard N2 Compute Engine virtual machines. The workload operates predictably for 12 hours every day throughout a 30-day month (360 total hours). When reviewing the baseline cost breakdown, how does the Google Cloud Pricing Calculator apply Sustained Use Discounts (SUDs) to this workload configuration?
- Sustained Use Discounts are applied incrementally because the instances run for more than 25% of the billing month (182.5 hours), though at a lower effective discount percentage than if they ran continuously 24/7.Cevap
- BSustained Use Discounts are not applied unless an explicit 1-year or 3-year Committed Use Discount (CUD) agreement is selected in the calculator settings.
- CSustained Use Discounts apply a flat 30% reduction immediately upon provisioning the virtual machines, regardless of the total hours operated within the billing cycle.
- DSustained Use Discounts require converting the Compute Engine VMs to Spot instances in the calculator to unlock running-hour discounts.
Cevap
Sustained Use Discounts are applied incrementally because the instances run for more than 25% of the billing month (182.5 hours), though at a lower effective discount percentage than if they ran continuously 24/7.
In Google Cloud Compute Engine pricing, Sustained Use Discounts (SUDs) automatically apply to supported machine families (such as N1 and N2) when an instance runs for more than 25% of a billing month (182.5 hours out of 730 average hours). Running a VM for 12 hours daily (360 hours/month) exceeds the 25% threshold, so the Pricing Calculator factors in a tiered incremental discount. However, because the instance is not running continuously all month, the blended discount percentage is smaller than the maximum discount applied to 24/7 instances.
