Scheduled scaling in AWS - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is scheduled scaling in cloud infrastructure?

Scheduled scaling is a way to automatically adjust the number of resources, like servers, at specific times. It helps prepare for expected changes in demand, like more users during the day and fewer at night.

beginner

Why use scheduled scaling instead of manual scaling?

Scheduled scaling saves time and reduces errors by automatically changing resource levels at set times. This ensures resources are ready when needed without waiting for someone to act.

beginner

In AWS, which service commonly uses scheduled scaling?

AWS Auto Scaling groups use scheduled scaling to increase or decrease the number of EC2 instances based on a schedule you set.

beginner

What is a real-life example of scheduled scaling?

Imagine a coffee shop that knows more customers come in the morning. They schedule more staff to work then and fewer in the afternoon. Scheduled scaling does the same for cloud resources.

beginner

What is a key benefit of scheduled scaling for cost management?

Scheduled scaling helps reduce costs by lowering resources when demand is low, so you don’t pay for unused capacity.

What does scheduled scaling do in cloud services?

A Backs up data regularly

B Automatically adjusts resources at set times

C Monitors security threats

D Manually adds resources when requested

Scheduled scaling automatically changes resource levels based on a schedule.

Which AWS service uses scheduled scaling to manage server numbers?

A AWS Lambda

B Amazon S3

C Auto Scaling groups

D Amazon RDS

Auto Scaling groups adjust EC2 instance counts using scheduled scaling.

What is a main advantage of scheduled scaling?

A Prepares resources before demand spikes

B Increases manual work

C Deletes unused data

D Encrypts all data

Scheduled scaling prepares resources ahead of expected demand increases.

Scheduled scaling helps reduce costs by:

A Lowering resources when demand is low

B Increasing resources randomly

C Running all resources 24/7

D Backing up data frequently

It lowers resources during low demand to avoid paying for unused capacity.

Which scenario best fits scheduled scaling?

A Scaling resources only when a problem occurs

B Scaling resources randomly

C Never changing resource levels

D Scaling resources based on a fixed daily schedule

Scheduled scaling adjusts resources based on a planned schedule.
