Concurrency and scaling in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is concurrency in cloud computing?

Concurrency means handling many tasks or users at the same time without waiting for one to finish before starting another.

beginner

What does scaling mean in cloud services?

Scaling means changing the amount of resources (like servers or CPUs) to handle more or fewer users or tasks.

What is the difference between vertical and horizontal scaling?

Vertical scaling adds more power (CPU, RAM) to one machine. Horizontal scaling adds more machines to share the work.

How does Google Cloud Run handle concurrency?

Cloud Run lets multiple requests run at the same time in one container instance, improving resource use and speed.

beginner

Why is autoscaling important in cloud environments?

Autoscaling automatically adds or removes resources based on demand, saving money and keeping apps fast.

What does horizontal scaling involve?

A Adding more machines to share the workload

B Adding more CPU and RAM to one machine

C Reducing the number of users

D Stopping some services temporarily

Horizontal scaling means adding more machines to handle more work.

Which Google Cloud service automatically scales container instances based on traffic?

A BigQuery

B Cloud Storage

C Cloud Functions

D Cloud Run

Cloud Run automatically scales containers up or down depending on incoming requests.

What is concurrency best described as?

A Handling multiple tasks at the same time

B Adding more servers

C Stopping tasks to save resources

D Backing up data

Concurrency means doing many tasks simultaneously.

Why is autoscaling useful?

A It requires manual setup for each change

B It adjusts resources automatically to match demand

C It only works during business hours

D It reduces security risks

Autoscaling changes resources automatically to keep performance and save costs.

Vertical scaling means:

A Splitting tasks into smaller parts

B Adding more machines

C Adding more power to one machine

D Reducing the number of users

Vertical scaling means increasing CPU, RAM, or storage on a single machine.

Explain how concurrency and scaling work together in a cloud application.

Think about how many users can use an app at the same time and how the cloud adds resources.

Describe the difference between vertical and horizontal scaling with examples.

Imagine upgrading your computer vs buying more computers.
