Cloud deployment models (public, private, hybrid) in AWS - Mini Project: Build & Apply

Understanding Cloud Deployment Models with AWS

📖 Scenario: You are working as a cloud architect for a company that wants to understand different cloud deployment models. They want to see examples of how to set up resources in public, private, and hybrid cloud environments using AWS.

🎯 Goal: Build simple AWS infrastructure configurations that represent public, private, and hybrid cloud deployment models. You will create data structures and configurations that define these models step-by-step.

📋 What You'll Learn

Create a dictionary named deployment_models with keys for 'public', 'private', and 'hybrid'.

Add a configuration variable aws_region set to 'us-east-1'.

Define the core logic by adding example AWS resource types for each deployment model inside deployment_models.

Complete the setup by adding a deployment_summary dictionary that summarizes the number of resource types per model.

💡 Why This Matters

🌍 Real World

Cloud architects often need to explain and plan different deployment models using cloud services like AWS.

💼 Career

Understanding deployment models helps in designing cloud infrastructure that meets business needs for security, cost, and scalability.

1

Create the initial deployment models dictionary

Create a dictionary called deployment_models with keys 'public', 'private', and 'hybrid'. Each key should have an empty list as its value.

AWS

# Create the deployment_models dictionary with empty lists for each model
# Your code here

Hint

Think of deployment_models as a container that holds lists of resources for each cloud model.

2

Add AWS region configuration

Add a variable called aws_region and set it to the string 'us-east-1'.

AWS

deployment_models = {
    'public': [],
    'private': [],
    'hybrid': []
}
# Set the AWS region
# Your code here

Hint

The AWS region tells where your cloud resources will be located.

3

Add example AWS resources to each deployment model

Add these AWS resource types as strings to the lists inside deployment_models: For 'public', add 'EC2' and 'S3'. For 'private', add 'VPC' and 'RDS'. For 'hybrid', add 'DirectConnect' and 'Lambda'.

AWS

deployment_models = {
    'public': [],
    'private': [],
    'hybrid': []
}
aws_region = 'us-east-1'
# Add AWS resource types to each deployment model
# Your code here

Hint

Think of these as examples of services used in each cloud model.

4

Create a summary of resource counts per deployment model

Create a dictionary called deployment_summary where each key is a deployment model from deployment_models and each value is the count of AWS resource types in that model's list.

AWS

deployment_models = {
    'public': ['EC2', 'S3'],
    'private': ['VPC', 'RDS'],
    'hybrid': ['DirectConnect', 'Lambda']
}
aws_region = 'us-east-1'
# Create deployment_summary with counts of resources per model
# Your code here

Hint

Use the len() function to count items in each list.

Practice

1. Which cloud deployment model provides resources shared among many users and is managed by providers like AWS?

easy

A. Community cloud

B. Private cloud

C. Hybrid cloud

D. Public cloud

Solution

1. Step 1: Understand public cloud characteristics

   Public cloud offers shared resources managed by third-party providers like AWS.

2. Step 2: Compare with other models

   Private cloud is dedicated, hybrid combines both, community cloud is shared by organizations with common concerns.

3. Final Answer:

   Public cloud -> Option D

4. Quick Check:

   Shared resources managed by providers = Public cloud [OK]

Hint: Public cloud means shared and managed by providers like AWS [OK]

Common Mistakes:

• Confusing private cloud with public cloud
• Thinking hybrid cloud is fully public
• Mixing community cloud with public cloud

2. Which of the following is the correct description of a private cloud?

easy

A. Cloud resources dedicated to a single organization

B. Cloud resources shared publicly with many users

C. Cloud resources managed by multiple providers

D. Cloud resources only for government use

Solution

1. Step 1: Define private cloud

   Private cloud means resources are dedicated to one organization for better security and control.

2. Step 2: Eliminate incorrect options

   Public sharing is not private, multiple providers relate to hybrid or public, government-only is not a standard model.

3. Final Answer:

   Cloud resources dedicated to a single organization -> Option A

4. Quick Check:

   Dedicated resources = Private cloud [OK]

Hint: Private cloud means dedicated to one organization only [OK]

Common Mistakes:

• Choosing public cloud for private cloud question
• Confusing government-only cloud with private cloud
• Thinking private cloud is shared

3. A company uses a cloud setup where sensitive data is stored on their own servers, but they use AWS public cloud for running web applications. What type of cloud deployment model is this?

medium

A. Hybrid cloud

B. Private cloud

C. Community cloud

D. Public cloud

Solution

1. Step 1: Identify private and public parts

   Sensitive data on own servers means private cloud; web apps on AWS means public cloud.

2. Step 2: Recognize combined model

   Using both private and public clouds together is called hybrid cloud.

3. Final Answer:

   Hybrid cloud -> Option A

4. Quick Check:

   Combination of private and public = Hybrid cloud [OK]

Hint: Mix of private and public cloud is hybrid cloud [OK]

Common Mistakes:

• Choosing only public or private cloud
• Confusing community cloud with hybrid
• Ignoring the mixed usage

4. A company wants to fix an error in their cloud deployment where their private cloud resources are accidentally exposed to the public internet. What is the best immediate action?

medium

A. Switch to a public cloud provider

B. Move all data to a hybrid cloud

C. Review and update firewall and access controls

D. Delete all cloud resources

Solution

1. Step 1: Identify the security issue

   Private cloud resources exposed means access controls or firewall rules are misconfigured.

2. Step 2: Apply correct fix

   Updating firewall and access controls will restrict unwanted public access immediately.

3. Final Answer:

   Review and update firewall and access controls -> Option C

4. Quick Check:

   Fix exposure by access control update [OK]

Hint: Fix exposure by updating firewall and access controls [OK]

Common Mistakes:

• Switching cloud models without fixing security
• Deleting resources unnecessarily
• Moving data without fixing access rules

5. A startup wants to minimize costs but keep sensitive customer data secure. They plan to use AWS public cloud for most services but keep the database on their own servers. Which cloud deployment model fits best and why?

hard

A. Private cloud, because all data stays on own servers

B. Hybrid cloud, because it balances cost and security

C. Public cloud, because it is cheapest and easiest

D. Community cloud, because it shares resources with similar startups

Solution

1. Step 1: Analyze cost and security needs

   Startup wants low cost (public cloud) and secure data (private servers).

2. Step 2: Match deployment model

   Hybrid cloud combines public cloud cost benefits with private cloud security for sensitive data.

3. Final Answer:

   Hybrid cloud, because it balances cost and security -> Option B

4. Quick Check:

   Cost + security balance = Hybrid cloud [OK]

Hint: Hybrid cloud balances cost and security needs [OK]

Common Mistakes:

• Choosing only public cloud ignoring security
• Choosing private cloud ignoring cost
• Confusing community cloud with hybrid
