Launching an EC2 instance in AWS - Mini Project: Build & Apply

Launching an EC2 instance

📖 Scenario: You are setting up a simple virtual server in the cloud using Amazon Web Services (AWS). This server will run a basic web application. To do this, you need to launch an EC2 instance, which is like renting a computer in the cloud.

🎯 Goal: Create a configuration to launch an EC2 instance with a specific name, instance type, and Amazon Machine Image (AMI) ID.

📋 What You'll Learn

Create a dictionary called ec2_instance with keys 'Name', 'InstanceType', and 'ImageId'.

Add a variable called instance_count to specify how many instances to launch.

Write a loop that creates a list called instances containing instance_count copies of ec2_instance.

Add a final configuration dictionary called launch_config that includes instances and a Region key.

💡 Why This Matters

🌍 Real World

Launching EC2 instances is a common task when deploying applications or services in the cloud. This project simulates preparing the configuration before actually launching servers.

💼 Career

Cloud engineers and developers often write scripts or use configuration files to automate launching and managing cloud resources like EC2 instances.

1

Create the EC2 instance data

Create a dictionary called ec2_instance with these exact entries: 'Name': 'MyWebServer', 'InstanceType': 't2.micro', and 'ImageId': 'ami-0abcdef1234567890'.

AWS

# Create the EC2 instance dictionary with Name, InstanceType, and ImageId
# Your code here

Need a hint?

Use curly braces to create a dictionary with the exact keys and values.

2

Set the number of instances to launch

Create a variable called instance_count and set it to 3 to specify launching three instances.

AWS

ec2_instance = {
    'Name': 'MyWebServer',
    'InstanceType': 't2.micro',
    'ImageId': 'ami-0abcdef1234567890'
}
# Set instance_count to 3
# Your code here

Need a hint?

Just assign the number 3 to the variable instance_count.

3

Create a list of instances

Use a for loop with variable i and range(instance_count) to create a list called instances containing instance_count copies of ec2_instance.

AWS

ec2_instance = {
    'Name': 'MyWebServer',
    'InstanceType': 't2.micro',
    'ImageId': 'ami-0abcdef1234567890'
}
instance_count = 3
# Create an empty list called instances
instances = []
# Use a for loop to add ec2_instance copies to instances
# Your code here

Need a hint?

Start with an empty list and add the same dictionary multiple times using a loop.

4

Add the final launch configuration

Create a dictionary called launch_config with keys 'Region' set to 'us-east-1' and 'Instances' set to the instances list.

AWS

ec2_instance = {
    'Name': 'MyWebServer',
    'InstanceType': 't2.micro',
    'ImageId': 'ami-0abcdef1234567890'
}
instance_count = 3
instances = []
for i in range(instance_count):
    instances.append(ec2_instance)
# Create launch_config dictionary with Region and Instances keys
# Your code here

Need a hint?

Use a dictionary with the exact keys and values as specified.
