Cloud Functions pricing in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are the main factors that affect the cost of Google Cloud Functions?

The main factors are the number of function invocations, the compute time (how long your function runs), and the amount of memory allocated to the function.

beginner

How does Google Cloud Functions charge for compute time?

Compute time is charged based on the time your function runs, measured in 100-millisecond increments, multiplied by the memory size allocated to the function.

beginner

What is a free tier in Cloud Functions pricing?

The free tier offers a monthly allowance of free invocations, compute time, and networking, so you can run small workloads without cost.

Why is memory allocation important in Cloud Functions pricing?

Because cost depends on memory size and execution time, choosing the right memory size helps balance performance and cost.

How does network egress affect Cloud Functions pricing?

Network egress (data sent out from the function) is charged separately based on the volume of data leaving Google Cloud, which can add to the total cost.

Which of the following does NOT directly affect Cloud Functions pricing?

A Number of function invocations

B Function execution time

C Memory allocated to the function

D Number of users accessing the function's website

Pricing depends on invocations, execution time, and memory, not on the number of users accessing a website.

How is compute time measured for billing in Cloud Functions?

A Per 100 milliseconds

B Per second

C Per minute

D Per hour

Compute time is billed in 100-millisecond increments.

What does the free tier for Cloud Functions include?

A Unlimited invocations

B Free invocations, compute time, and networking up to a limit

C Free storage space

D Free database queries

The free tier includes a monthly limit of free invocations, compute time, and networking.

Why should you choose the right memory size for your Cloud Function?

A To improve security

B To reduce latency only

C To balance performance and cost

D Memory size does not affect cost

Memory size affects both performance and cost, so choosing the right size is important.

What is network egress in Cloud Functions pricing?

A Data sent out from the function

B Data sent into the function

C Internal data processing

D Function invocation count

Network egress is the data sent out from the function and is charged separately.

Explain how Google Cloud Functions pricing works including the main cost factors and the role of the free tier.

Think about what you pay for when your function runs and how Google offers some free usage.

Describe why memory size and execution time are important when estimating Cloud Functions cost.

Consider how longer running or bigger memory functions cost more.
