CloudFormation is a service provided by AWS that allows you to manage your infrastructure and application resources using __. It enables you to define your resources and their dependencies in a declarative template, which can be version-controlled and easily shared.

With CloudFormation, you can create, update, and delete AWS resources in a consistent and predictable manner. Instead of manually provisioning resources, you can use CloudFormation templates to automate the process, reducing the potential for errors and ensuring infrastructure consistency across environments.

CloudFormation templates are written in __ or ____ and can include various resource types, such as EC2 instances, S3 buckets, databases, security groups, and more. You can specify properties, dependencies, and configuration options for each resource in the template.

CloudFormation provides a wide range of features to manage your infrastructure, including stack management, resource tracking, drift detection, and stack policies. You can also use CloudFormation to implement complex workflows and manage dependencies between resources.

By using CloudFormation, you can treat your infrastructure as code, applying software engineering practices to manage and version your infrastructure resources. This helps improve collaboration, scalability, and maintainability of your AWS deployments.

Python code snippet to demonstrate the concept of CloudFormation:

1import boto3
2
3client = boto3.client('cloudformation')
4
5def create_stack(stack_name, template_body):
6    response = client.create_stack(
7        StackName=stack_name,
8        TemplateBody=template_body
9    )
10    return response
11
12stack_name = 'MyStack'
13template_body = '''
14{
15  "Resources": {
16    "MyBucket": {
17      "Type": "AWS::S3::Bucket",
18      "Properties": {
19        "BucketName": "my-bucket"
20      }
21    }
22  }
23}"
24
25response = create_stack(stack_name, template_body)
26print(response)
