A cloud engineer is utilizing the Google Cloud Pricing Calculator to model monthly infrastructure costs for a baseline web service running continuous workloads on five `n2-standard-4` Compute Engine virtual machines in the `us-central1` region. The organization plans to run this workload uninterrupted for the next three years. Which configuration approach in the Pricing Calculator will yield the most accurate and cost-effective monthly estimate for these instances?
- Select a 3-Year Committed Use Discount (CUD) for the N2 compute instances, because committed use discounts offer deeper savings than automatic sustained use discounts for long-term continuous workloads.Answer
- BApply automatic Sustained Use Discounts (SUD) while simultaneously selecting a 3-Year Committed Use Discount to combine both discount models for maximum savings.
- CConfigure the virtual machines as Spot VMs combined with a 3-Year Committed Use Discount to achieve the lowest possible hourly instance price.
- DChange the boot disk persistent storage type to Coldline Cloud Storage within the instance configuration to reduce compute billing.
Answer
Selecting a 3-Year Committed Use Discount for the N2 instances in the GCP Pricing Calculator yields the accurate baseline cost estimate because CUDs provide the maximum available discount for predictable 24/7 workloads over long durations.
For continuous 24/7 Compute Engine workloads planned over a three-year horizon, selecting a 3-Year Committed Use Discount in the pricing calculator provides the highest percentage savings. Committed Use Discounts apply to predictable resource demands and supersede Sustained Use Discounts.
