Instance types and families in AWS - Mini Project: Build & Apply

Instance types and families

📖 Scenario: You are setting up a cloud environment and need to organize information about different AWS EC2 instance types and their families. This will help you choose the right instance for your applications.

🎯 Goal: Create a dictionary that holds AWS EC2 instance types grouped by their families. Then, add a configuration variable to select a family, filter the instance types by that family, and finally output the filtered list.

📋 What You'll Learn

Create a dictionary called instance_families with exact keys and values

Add a variable called selected_family with a specific family name

Use a list comprehension called filtered_instances to select instances from the chosen family

Add a final line that assigns result to filtered_instances

💡 Why This Matters

🌍 Real World

Organizing instance types by family helps cloud architects quickly select the right compute resources for different workloads.

💼 Career

Understanding instance types and families is essential for roles like cloud engineer, solutions architect, and DevOps specialist.

1

Create the instance families dictionary

Create a dictionary called instance_families with these exact entries: 'general_purpose': ['t2.micro', 't3.medium', 't3.large'], 'compute_optimized': ['c4.large', 'c5.xlarge', 'c5.2xlarge'], and 'memory_optimized': ['r4.large', 'r5.xlarge', 'r5.2xlarge'].

AWS

# Create the instance_families dictionary with specified keys and values
# Your code here

Need a hint?

Use curly braces to create a dictionary. Each key is a string and each value is a list of strings.

2

Add a selected family variable

Add a variable called selected_family and set it to the string 'compute_optimized'.

AWS

instance_families = {
    'general_purpose': ['t2.micro', 't3.medium', 't3.large'],
    'compute_optimized': ['c4.large', 'c5.xlarge', 'c5.2xlarge'],
    'memory_optimized': ['r4.large', 'r5.xlarge', 'r5.2xlarge']
}
# Set selected_family to 'compute_optimized'
# Your code here

Need a hint?

Assign the string 'compute_optimized' to the variable selected_family.

3

Filter instances by selected family

Create a list called filtered_instances using a list comprehension that selects all instance types from instance_families[selected_family].

AWS

instance_families = {
    'general_purpose': ['t2.micro', 't3.medium', 't3.large'],
    'compute_optimized': ['c4.large', 'c5.xlarge', 'c5.2xlarge'],
    'memory_optimized': ['r4.large', 'r5.xlarge', 'r5.2xlarge']
}
selected_family = 'compute_optimized'
# Use a list comprehension to create filtered_instances from instance_families[selected_family]
# Your code here

Need a hint?

Use a list comprehension to copy all instances from the selected family list.

4

Assign the final result

Add a line that assigns the variable result to the value of filtered_instances.

AWS

instance_families = {
    'general_purpose': ['t2.micro', 't3.medium', 't3.large'],
    'compute_optimized': ['c4.large', 'c5.xlarge', 'c5.2xlarge'],
    'memory_optimized': ['r4.large', 'r5.xlarge', 'r5.2xlarge']
}
selected_family = 'compute_optimized'
filtered_instances = [instance for instance in instance_families[selected_family]]
# Assign result to filtered_instances
# Your code here

Need a hint?

Simply assign the list filtered_instances to the variable result.
