A cloud engineer is using the Google Cloud Pricing Calculator to estimate the base monthly cost of a Compute Engine virtual machine instance. The pricing calculator specifies an hourly rate of $0.12\$0.12 for the selected machine configuration. Assuming the instance runs continuously for 730730 hours in a 30-day month, what is the total estimated baseline cost in USD before applying any sustained use or committed use discounts?

Cevabı ve açıklamayı göster

Cevap: 87.6

Cevap

The baseline cost for running the instance continuously for 730730 hours is $87.60\$87.60.
Multiplying the base rate of $0.12\$0.12 per hour by 730730 monthly hours gives $87.60\$87.60, which represents the raw cost prior to any discount structures.

Adım Adım Çözüm

1
Determine operational hours and hourly price
Hourly price = $0.12\$0.12, total monthly runtime = 730730 hours
The pricing calculator baseline estimate uses standard monthly operational hours multiplied by the hourly resource rate.
2
Compute total monthly compute charge
$0.12×730=$87.60\$0.12 \times 730 = \$87.60
Multiplying hourly cost by total elapsed running hours gives the total un-discounted monthly cost.

Calculate single instance hourly compute rate for vCPU and RAM
Gross hourly rate = (2×$0.033174)+(8×$0.004446)=$0.066348+$0.035568=$0.101916(2 \times \$0.033174) + (8 \times \$0.004446) = \$0.066348 + \$0.035568 = \$0.101916 per hour.
Custom VM pricing evaluates vCPU and memory allocation independently.

Gross monthly compute cost = 10×730×$0.101916=$743.986810 \times 730 \times \$0.101916 = \$743.9868.
Monthly compute allocation measures total instance hours before applying sustained usage discounts.

Net monthly compute cost = $743.9868×(10.30)=$743.9868×0.70=$520.79076\$743.9868 \times (1 - 0.30) = \$743.9868 \times 0.70 = \$520.79076.
N1 and custom workloads running continuously qualify for a 30% effective discount over a 730-hour month.

Calculate storage capacity and provisioned IOPS costs for Extreme Persistent Disks
Storage capacity cost = 10×200 GB×$0.125=$250.0010 \times 200\text{ GB} \times \$0.125 = \$250.00. Provisioned IOPS cost = 10×2,500 IOPS×$0.025=$625.0010 \times 2,500\text{ IOPS} \times \$0.025 = \$625.00. Total disk cost = $250.00+$625.00=$875.00\$250.00 + \$625.00 = \$875.00.
Extreme Persistent Disk pricing separates raw disk storage capacity from provisioned IOPS performance.

1
Calculate the discounted Compute Engine VM cost
$657.00
Base VM cost is 10 instances * 730 hours * 0.20/hr=0.20/hr = 1,460.00. Applying the 55% Committed Use Discount gives 1,460.00(10.55)=1,460.00 * (1 - 0.55) = 657.00.
2
Calculate the Standard Persistent Disk cost
$80.00
10 instances attached to 200 GB disks equal 2,000 GB total storage. 2,000 GB * 0.04/GB=0.04/GB = 80.00. Persistent disk storage is not eligible for Compute CUDs.
3
Calculate the net Internet egress cost
$58.80
The total egress of 500 GB minus the 10 GB monthly free tier leaves 490 billable GB. 490 GB * 0.12/GB=0.12/GB = 58.80.

Sum all monthly cost components
$795.80
Total cost = 657.00(Compute)+657.00 (Compute) + 80.00 (Storage) + 58.80(NetworkEgress)=58.80 (Network Egress) = 795.80.

Cevap: 436

Cevap

The net total monthly cost for compute and disk storage across all 10 virtual machines combined is $436.
The baseline compute cost per VM for 720 hours is 72.00(72.00 ( 0.10 * 720). A 3-year Committed Use Discount reduces compute costs by 45%, bringing the compute cost per VM down to 39.60(39.60 ( 72.00 * 0.55). Each VM's 100 GB persistent disk costs 4.00permonth(1004.00 per month (100 * 0.04) and is not subject to compute CUD discounts. Combining compute (39.60)andstorage(39.60) and storage ( 4.00) yields 43.60perVMpermonth.For10VMs,thetotalnetcostis43.60 per VM per month. For 10 VMs, the total net cost is 43.60 * 10 = $436.00.

A logistics platform models monthly infrastructure costs in the Google Cloud Pricing Calculator for a fleet tracking service. The workload requires 5 N1 compute instances running continuously for 730 hours per month at a baseline rate of 0.20perhourperinstance.GoogleCloudautomaticallyappliesa300.20 per hour per instance. Google Cloud automatically applies a 30% Sustained Use Discount (SUD) to N1 instance compute charges for 100% monthly utilization. In addition, each instance is attached to 200 GB of Standard Persistent Disk storage priced at 0.05 per GB per month. Note that Persistent Disk pricing is not eligible for Sustained Use Discounts. What is the total estimated monthly cost, in dollars, for this workload?

Cevap

The total estimated monthly cost for the workload is $561.00.
The correct calculation computes the baseline compute cost (730.00),appliesthe30730.00), applies the 30% Sustained Use Discount to arrive at 511.00, and adds the un-discounted Persistent Disk cost of 50.00toyieldatotalmonthlycostof50.00 to yield a total monthly cost of 561.00.

Adım Adım Çözüm

1
Calculate the gross compute cost for all instances.
$730.00
5 instances running for 730 hours each at 0.20/hourequals57300.20/hour equals 5 * 730 * 0.20 = $730.00.
2
Apply the Sustained Use Discount (SUD) to compute charges.
$511.00
Continuous monthly usage on N1 instances qualifies for a 30% discount on compute charges (730.000.70=730.00 * 0.70 = 511.00).
3
Calculate the total Persistent Disk storage cost.
$50.00
5 instances with 200 GB each equals 1,000 GB total at $0.05/GB/month. Persistent Disk is not eligible for SUD.
4
Sum the net compute cost and persistent storage cost.
$561.00
511.00(netcompute)+511.00 (net compute) + 50.00 (storage) = $561.00.

Sustained Use Discounts apply automatically to eligible Compute Engine VM instance hours but do not apply to attached Persistent Disk storage.

A cloud engineer is using the Google Cloud Pricing Calculator to estimate monthly Compute Engine expenses for a single virtual machine instance. The instance has an un-discounted rate of $0.04\$0.04 per hour. If the instance runs continuously for 730730 hours during a month and qualifies for a 20%20\% sustained use discount on its compute costs, what is the net estimated monthly cost of the instance in USD?

Cevap: 23.36

Cevap

The net estimated monthly cost of the instance is $23.36\$23.36.
To estimate the total monthly cost, multiply the hourly rate of $0.04\$0.04 by 730730 hours to determine the gross monthly cost of $29.20\$29.20. Applying the 20%20\% sustained use discount reduces the total cost by $5.84\$5.84 ($29.20×0.20\$29.20 \times 0.20), resulting in a net monthly estimate of $23.36\$23.36.

Adım Adım Çözüm

1
Calculate total gross monthly cost prior to discounts.
$29.20\$29.20
Multiply the hourly rate ($0.04\$0.04) by the number of continuous operational hours (730730).
2
Apply the 20%20\% sustained use discount factor.
$23.36\$23.36
Multiply the gross cost by 0.800.80 to account for a 20%20\% reduction.
