A system architect is using the Google Cloud Pricing Calculator to project monthly infrastructure expenses for a data pipeline operating in the `us-central1` region for a $30$ -day month ( $720$ total hours).

The architecture consists of the following components:
- $8$ identical Compute Engine instances with a baseline on-demand cost of $\$0.30$ per hour per instance.
- A $1$ -year Committed Use Discount (CUD) covering $6$ of these instances, providing a $37\%$ discount off their on-demand rate.
- The remaining $2$ instances run continuously on-demand and qualify for a Sustained Use Discount (SUD) of $20\%$ applied to their hourly rate.
- $500\text{ GB}$ of Standard Cloud Storage at $\$0.02$ per $\text{GB/month}$ .
- $100\text{ GB}$ of internet data egress at $\$0.08$ per $\text{GB}$ .

What is the total estimated monthly cost, in USD, for this infrastructure setup?

Answer: 1180.08 USD

Answer

The total estimated monthly cost is $1,180.08.

The total estimate of

1,180.08 accurately accounts for 6 CUD instances discounted at 37% (

816.48), 2 SUD instances discounted at 20% (

345.60), 500 GB of Standard Cloud Storage (

10.00), and 100 GB of network egress ($8.00).

Step-by-Step Solution

Calculate the monthly cost for the Committed Use Discount (CUD) Compute Engine instances.

6 instances × (

0.30 × 0.63) × 720 hours =

816.48

Applying the 37% CUD discount reduces the hourly rate to $0.189 per instance.

Calculate the monthly cost for the Sustained Use Discount (SUD) Compute Engine instances.

2 instances × (

0.30 × 0.80) × 720 hours =

345.60

Applying the 20% SUD discount for 100% continuous monthly runtime reduces the hourly rate to $0.24 per instance.

Calculate the monthly Cloud Storage and Data Egress expenses.

Storage: 500 GB ×

0.02 =

10.00; Egress: 100 GB ×

0.08 =

8.00. Total auxiliary = $18.00

Storage and network egress rates apply per GB ingested and transferred out of the region.

Sum all compute, storage, and networking sub-totals.

816.48 +

345.60 +

10.00 +

8.00 = $1,180.08

Combines all resource components into the total monthly GCP bill estimate.
