Minimum, maximum, and desired capacity in AWS - Mini Project: Build & Apply

Minimum, maximum, and desired capacity

📖 Scenario: You are managing a cloud application that needs to automatically adjust the number of servers running based on demand. To do this, you will set up an Auto Scaling Group with specific minimum, maximum, and desired capacity values.

🎯 Goal: Create an AWS Auto Scaling Group configuration that defines the minimum number of instances as 2, the maximum number of instances as 5, and the desired capacity as 3.

📋 What You'll Learn

Create a dictionary called asg_config to hold the Auto Scaling Group settings.

Add keys MinSize, MaxSize, and DesiredCapacity with the exact values 2, 5, and 3 respectively.

Use the exact key names and values as specified.

Ensure the configuration is valid for AWS Auto Scaling Group settings.

💡 Why This Matters

🌍 Real World

Auto Scaling Groups automatically adjust the number of servers to handle changes in traffic, saving costs and improving performance.

💼 Career

Understanding how to configure minimum, maximum, and desired capacity is essential for cloud engineers managing scalable applications.

1

Create the initial Auto Scaling Group configuration dictionary

Create a dictionary called asg_config with the keys MinSize, MaxSize, and DesiredCapacity set to 0 initially.

AWS

# Create the asg_config dictionary with MinSize, MaxSize, and DesiredCapacity set to 0
# Your code here

Need a hint?

Use curly braces to create a dictionary and set each key to 0.

2

Add the minimum capacity value

Update the asg_config dictionary to set the MinSize key to the integer value 2.

AWS

asg_config = {
    'MinSize': 0,
    'MaxSize': 0,
    'DesiredCapacity': 0
}
# Set MinSize to 2 below
# Your code here

Need a hint?

Change the value for the key 'MinSize' to 2.

3

Add the maximum capacity value

Update the asg_config dictionary to set the MaxSize key to the integer value 5.

AWS

asg_config = {
    'MinSize': 2,
    'MaxSize': 0,
    'DesiredCapacity': 0
}
# Set MaxSize to 5 below
# Your code here

Need a hint?

Change the value for the key 'MaxSize' to 5.

4

Add the desired capacity value

Update the asg_config dictionary to set the DesiredCapacity key to the integer value 3.

AWS

asg_config = {
    'MinSize': 2,
    'MaxSize': 5,
    'DesiredCapacity': 0
}
# Set DesiredCapacity to 3 below
# Your code here

Need a hint?

Change the value for the key 'DesiredCapacity' to 3.
