Spot Instances for cost savings in AWS - Mini Project: Build & Apply

Spot Instances for cost savings

📖 Scenario: You are managing a cloud infrastructure for a small company. You want to save money by using AWS Spot Instances, which are cheaper but can be interrupted. You will create a simple configuration to launch a Spot Instance with a specific instance type and maximum price.

🎯 Goal: Build an AWS EC2 Spot Instance request configuration using JSON that specifies the instance type, maximum price, and launch specifications.

📋 What You'll Learn

Create a JSON object named spot_request with the key InstanceCount set to 1

Add a key SpotPrice with the value "0.05" (maximum price in USD)

Include a nested object LaunchSpecification with the key InstanceType set to "t3.micro"

Add the key ImageId inside LaunchSpecification with the value "ami-0abcdef1234567890" (example AMI ID)

💡 Why This Matters

🌍 Real World

Companies use Spot Instances to reduce cloud costs by bidding on spare capacity. This project shows how to configure such requests.

💼 Career

Cloud engineers and DevOps professionals often create and manage Spot Instance requests to optimize infrastructure spending.

1

Create the initial Spot Instance request structure

Create a JSON object called spot_request with the key InstanceCount set to 1.

AWS

# Your code here

Need a hint?

Use curly braces to create a dictionary and set InstanceCount to 1.

2

Add the maximum Spot price

Add a key SpotPrice with the value "0.05" to the spot_request dictionary.

AWS

spot_request = {
    "InstanceCount": 1,
    # Add SpotPrice key here
}

Need a hint?

Add the SpotPrice key with the string value "0.05" inside the dictionary.

3

Add launch specifications with instance type

Add a nested dictionary LaunchSpecification inside spot_request with the key InstanceType set to "t3.micro".

AWS

spot_request = {
    "InstanceCount": 1,
    "SpotPrice": "0.05",
    # Add LaunchSpecification dictionary here
}

Need a hint?

Create a nested dictionary for LaunchSpecification with the key InstanceType set to "t3.micro".

4

Add the AMI ID to launch specifications

Inside the LaunchSpecification dictionary, add the key ImageId with the value "ami-0abcdef1234567890".

AWS

spot_request = {
    "InstanceCount": 1,
    "SpotPrice": "0.05",
    "LaunchSpecification": {
        "InstanceType": "t3.micro",
        # Add ImageId here
    }
}

Need a hint?

Add the ImageId key with the example AMI ID inside the LaunchSpecification dictionary.
