Cloud service models (IaaS, PaaS, SaaS) in AWS - Mini Project: Build & Apply

Understanding Cloud Service Models: IaaS, PaaS, SaaS

📖 Scenario: You are learning about cloud computing. You want to organize examples of cloud service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). This will help you understand how cloud providers offer different levels of services.

🎯 Goal: Create a simple AWS-themed dictionary that lists examples of IaaS, PaaS, and SaaS services. Then, add a configuration variable to select one model. Next, write code to get the list of services for the selected model. Finally, add a print statement to show the selected services.

📋 What You'll Learn

Create a dictionary named cloud_services with keys 'IaaS', 'PaaS', and 'SaaS' and their AWS service examples as lists

Create a variable named selected_model and set it to 'PaaS'

Write code to get the list of services for selected_model from cloud_services and store it in services_list

Add a print statement to display services_list

💡 Why This Matters

🌍 Real World

Cloud architects and developers often categorize cloud services to choose the right model for their applications.

💼 Career

Understanding IaaS, PaaS, and SaaS helps in designing cloud solutions and communicating with teams and clients.

1

Create the cloud services dictionary

Create a dictionary called cloud_services with these exact keys and values: 'IaaS' with ['EC2', 'EBS', 'VPC'], 'PaaS' with ['Elastic Beanstalk', 'Lambda', 'RDS'], and 'SaaS' with ['WorkMail', 'Chime', 'QuickSight'].

# Create the cloud_services dictionary with AWS service examples
# Your code here

Need a hint?

Use curly braces to create a dictionary. Keys are strings and values are lists of strings.

2

Set the selected cloud service model

Create a variable called selected_model and set it to the string 'PaaS'.

AWS

cloud_services = {
    'IaaS': ['EC2', 'EBS', 'VPC'],
    'PaaS': ['Elastic Beanstalk', 'Lambda', 'RDS'],
    'SaaS': ['WorkMail', 'Chime', 'QuickSight']
}
# Set selected_model to 'PaaS'
# Your code here

Need a hint?

Assign the string 'PaaS' to the variable selected_model.

3

Get services list for the selected model

Write code to get the list of services for the cloud service model stored in selected_model from the cloud_services dictionary. Store this list in a variable called services_list.

AWS

cloud_services = {
    'IaaS': ['EC2', 'EBS', 'VPC'],
    'PaaS': ['Elastic Beanstalk', 'Lambda', 'RDS'],
    'SaaS': ['WorkMail', 'Chime', 'QuickSight']
}
selected_model = 'PaaS'
# Get the services list for selected_model
# Your code here

Need a hint?

Use the variable selected_model as the key to get the value from cloud_services.

4

Display the selected services

Add a print statement to display the contents of the variable services_list.

AWS

cloud_services = {
    'IaaS': ['EC2', 'EBS', 'VPC'],
    'PaaS': ['Elastic Beanstalk', 'Lambda', 'RDS'],
    'SaaS': ['WorkMail', 'Chime', 'QuickSight']
}
selected_model = 'PaaS'
services_list = cloud_services[selected_model]
# Print the services_list
# Your code here

Need a hint?

Use the print() function to show the list of services.
