App Service plans and pricing tiers in Azure - Mini Project: Build & Apply

App Service plans and pricing tiers

📖 Scenario: You are setting up a web application on Azure. To host your app, you need to create an App Service plan. This plan defines the resources and pricing tier your app will use.Think of an App Service plan like renting an apartment: the size and features you choose affect the cost and what you can do inside.

🎯 Goal: Create an Azure App Service plan with a specific pricing tier. You will first define the basic plan details, then add a pricing tier, and finally complete the configuration to deploy the plan.

📋 What You'll Learn

Create a variable called app_service_plan with the name and location of the plan

Add a variable called pricing_tier with the value Standard_S1

Use the pricing_tier variable to set the SKU of the app_service_plan

Complete the configuration by adding the kind attribute with value app

💡 Why This Matters

🌍 Real World

App Service plans are used in real Azure cloud projects to allocate resources and pricing for web applications.

💼 Career

Understanding how to configure App Service plans is essential for cloud engineers and developers working with Azure.

1

Create the initial App Service plan data

Create a dictionary called app_service_plan with these exact entries: name set to "MyAppServicePlan" and location set to "East US".

Azure

# Create the app_service_plan dictionary with name and location
# Your code here

Hint

Use a Python dictionary with keys name and location.

2

Add the pricing tier variable

Create a variable called pricing_tier and set it to the string "Standard_S1".

Azure

app_service_plan = {
    "name": "MyAppServicePlan",
    "location": "East US"
}
# Create pricing_tier variable with value "Standard_S1"
# Your code here

Hint

Just assign the string "Standard_S1" to pricing_tier.

3

Set the SKU of the App Service plan

Add a key called sku to the app_service_plan dictionary and set its value to the pricing_tier variable.

Azure

app_service_plan = {
    "name": "MyAppServicePlan",
    "location": "East US"
}

pricing_tier = "Standard_S1"
# Add sku key to app_service_plan with value pricing_tier
# Your code here

Hint

Use app_service_plan["sku"] = pricing_tier or add it directly in the dictionary.

4

Complete the App Service plan configuration

Add a key called kind to the app_service_plan dictionary and set its value to the string "app".

Azure

app_service_plan = {
    "name": "MyAppServicePlan",
    "location": "East US",
    "sku": pricing_tier
}

pricing_tier = "Standard_S1"
# Add kind key to app_service_plan with value "app"
# Your code here

Hint

Adding "kind": "app" completes the plan configuration.

Practice

1. What does an Azure App Service plan primarily define for your web app?

easy

A. The amount of computing resources like CPU and memory allocated

B. The programming language your app uses

C. The number of users who can access your app

D. The database type your app connects to

Solution

1. Step 1: Understand the role of an App Service plan

   An App Service plan defines the compute resources such as CPU, memory, and storage that your app will use.

2. Step 2: Differentiate from other app settings

   It does not control programming language, user count, or database type, which are separate configurations.

3. Final Answer:

   The amount of computing resources like CPU and memory allocated -> Option A

4. Quick Check:

   App Service plan = compute resources [OK]

Hint: App Service plan = resources your app runs on [OK]

Common Mistakes:

• Confusing App Service plan with app code or database
• Thinking it controls user access limits
• Assuming it sets programming language

2. Which of the following is the correct way to specify a Standard pricing tier in an Azure App Service plan using Azure CLI?

easy

A. az appservice plan create --name MyPlan --resource-group MyGroup --plan-tier Standard

B. az appservice plan create --name MyPlan --resource-group MyGroup --sku Standard

C. az appservice plan create --name MyPlan --resource-group MyGroup --pricing-tier Standard

D. az appservice plan create --name MyPlan --resource-group MyGroup --tier Standard

Solution

1. Step 1: Recall Azure CLI syntax for App Service plan creation

   The correct parameter to specify pricing tier is '--sku' followed by the tier name like 'Standard'.

2. Step 2: Verify other options

   Options using '--tier', '--pricing-tier', or '--plan-tier' are invalid parameters and will cause errors.

3. Final Answer:

   az appservice plan create --name MyPlan --resource-group MyGroup --sku Standard -> Option B

4. Quick Check:

   Use --sku to set pricing tier [OK]

Hint: Use --sku to set tier in Azure CLI [OK]

Common Mistakes:

• Using incorrect parameter names like --tier or --pricing-tier
• Confusing plan name with tier parameter
• Omitting the resource group

3. Given an App Service plan with pricing tier set to 'Basic', what will happen if you try to enable autoscaling for your app?

medium

A. Autoscaling is enabled by default on Basic tier

B. Autoscaling will work because Basic tier supports it

C. Autoscaling will work only during business hours

D. Autoscaling will fail because Basic tier does not support autoscale

Solution

1. Step 1: Understand autoscaling support by pricing tiers

   Autoscaling is supported starting from the Standard tier and above, not in Basic tier.

2. Step 2: Apply this to the Basic tier scenario

   Since Basic tier lacks autoscale support, attempts to enable it will fail or be blocked.

3. Final Answer:

   Autoscaling will fail because Basic tier does not support autoscale -> Option D

4. Quick Check:

   Basic tier = no autoscale support [OK]

Hint: Autoscale needs Standard or higher tier [OK]

Common Mistakes:

• Assuming Basic tier supports autoscale
• Thinking autoscale is automatic on all tiers
• Confusing Basic with Standard tier features

4. You created an App Service plan with the SKU 'F1' but your app is not accessible publicly. What is the most likely cause?

medium

A. You must assign a custom domain to make it public

B. F1 tier does not support public access by default

C. F1 is a Free tier and may have limited outbound network access

D. F1 tier requires manual SSL configuration before public access

Solution

1. Step 1: Understand the Free (F1) tier limitations

   The Free tier (F1) has restrictions including limited outbound network access and possible cold start delays.

2. Step 2: Relate these limits to app accessibility

   Limited network access can cause the app to be unreachable or slow, but public access is allowed.

3. Final Answer:

   F1 is a Free tier and may have limited outbound network access -> Option C

4. Quick Check:

   F1 tier = limited network, possible access issues [OK]

Hint: Free tier has network limits causing access issues [OK]

Common Mistakes:

• Thinking Free tier blocks public access
• Assuming custom domain is required for public access
• Believing SSL setup is mandatory for access

5. You need to host a production web app with high traffic, custom domains, SSL, autoscaling, and daily backups. Which App Service plan pricing tier should you choose?

hard

A. Standard (S1)

B. Basic (B1)

C. Free (F1)

D. Shared (D1)

Solution

1. Step 1: Identify required features for production app

   High traffic, custom domains, SSL, autoscaling, and backups require a tier with advanced features.

2. Step 2: Match features to pricing tiers

   Standard tier supports autoscaling, custom domains, SSL, and backups. Basic lacks autoscaling and some features. Free and Shared tiers are limited.

3. Final Answer:

   Standard (S1) -> Option A

4. Quick Check:

   Production needs Standard tier features [OK]

Hint: Standard tier supports autoscale and backups [OK]

Common Mistakes:

• Choosing Free or Shared for production needs
• Assuming Basic supports autoscale
• Ignoring backup requirements
