Why cloud computing enables scale in Intro to Computing - Challenge Your Understanding

Challenge - 5 Problems

🧠 Conceptual

intermediate

How does cloud computing allow businesses to handle more users?

Imagine a small bakery that suddenly gets many more customers. How does cloud computing help a business like this handle more users easily?

A By quickly adding more servers and resources as needed without buying new hardware.

B By limiting the number of users to avoid overload.

C By requiring users to wait in a queue before accessing the service.

D By storing all data on a single computer to keep things simple.

💡 Hint

Think about how cloud services can grow or shrink resources based on demand.

Cloud computing allows businesses to add or remove computing resources quickly, like adding more ovens in a bakery when more customers arrive, without needing to buy physical machines.

Trace resource allocation in cloud scaling

Look at this simple flowchart of a cloud service scaling up when user demand increases. What is the correct order of steps?

A 1,3,2,4

B 2,1,3,4

C 1,2,3,4

D 3,2,1,4

💡 Hint

Think about what happens first: monitoring, detecting, then acting.

The system first monitors demand, detects if it is too high, adds servers automatically, and then users get smooth service.

❓ Comparison

Compare traditional servers vs cloud for scaling

Which statement best explains why cloud computing is better for scaling than traditional servers?

A Traditional servers automatically adjust resources based on demand, cloud does not.

B Traditional servers require buying and installing hardware, while cloud can add resources instantly.

C Cloud computing limits the number of users to prevent overload, unlike traditional servers.

D Traditional servers are cheaper and faster to scale than cloud.

💡 Hint

Think about how quickly resources can be added in each case.

Traditional servers need physical hardware purchases and setup, which takes time. Cloud computing can add resources instantly through software control.

❓ identification

advanced

Identify the key feature enabling cloud scalability

Which feature of cloud computing is most responsible for enabling easy scaling?

A Limiting user access to reduce load.

B Using only one large physical server for all tasks.

C Manual installation of software on each server.

D Virtualization that allows multiple virtual machines on one physical server.

💡 Hint

Think about how cloud providers run many virtual servers on fewer physical machines.

Virtualization lets cloud providers create many virtual servers on physical hardware, making it easy to add or remove resources quickly.

🚀 Application

Predict the effect of removing auto-scaling in cloud

If a cloud service disables automatic scaling, what is the most likely result when user demand suddenly spikes?

A The service may slow down or crash because it cannot add resources quickly.

B The service will handle the spike smoothly without any issues.

C The service will automatically reduce user numbers to match resources.

D The service will add resources manually without delay.

💡 Hint

Think about what happens if resources cannot increase automatically.

Without auto-scaling, the cloud service cannot quickly add resources, so it may become slow or crash under high demand.
