      ],
    });

    // Create a security group and attach the cost allocation tags
    const securityGroup = new ec2.SecurityGroup(this, 'MySecurityGroup', {
      vpc: vpc,
      description: 'My Security Group',
    });

    securityGroup.addTags({
      Name: 'MySecurityGroup',
      Env: 'Production',
    });
  }
}

This code will create an EC2 VPC, an EC2 instance, and an EC2 security group. It will also attach cost allocation tags to each of these resources.

Here is a breakdown of the code:

1. The import statements import the necessary modules. The cdk module is the core AWS CDK module, and the ec2 module provides constructs for working with EC2 resources.
2. The MyStack class is a custom CDK stack class that defines the resources to be created.
3. The constructor method initializes the stack and creates the VPC.
4. The vpcTags object creates a CloudFormation resource of type CfnTags. This resource is used to attach cost allocation tags to the VPC.
5. The instance object creates an EC2 instance and attaches the cost allocation tags to the instance.
6. The securityGroup object creates an EC2 security group and attaches the cost allocation tags to the security group.
