Reserved instance payment failed remediation

Using Console

To remediate the EC2 Reserved Instances payment failed misconfiguration in AWS, please follow the steps below:

Log in to your AWS Management Console.
Go to the EC2 dashboard.
Click on the “Reserved Instances” link on the left-hand side menu.
Find the Reserved Instance with the payment failed status and select it.
Click on the “Actions” button and select “Modify Reserved Instances”.
In the “Modify Reserved Instances” window, select the new payment option and click “Save Changes”.
If the payment information is correct, the Reserved Instance will be reactivated.

Alternatively, you can also remediate this misconfiguration using the AWS CLI by running the following command:

aws ec2 modify-reserved-instances --reserved-instances-id <reservation-id> --instance-count <new-instance-count> --payment-option <payment-option>

Replace <reservation-id> with the ID of the Reserved Instance that has the payment failed status, <new-instance-count> with the number of instances you want to reserve and <payment-option> with the new payment option you want to use.

Using CLI

Using Python

To remediate the misconfiguration “EC2 Reserved Instances Should Not Have Payment Failed” for AWS using python, you can follow the below steps:Step 1: Import the necessary libraries

import boto3

Step 2: Create an EC2 client object

ec2 = boto3.client('ec2')

Step 3: Get the list of all Reserved Instances

reserved_instances = ec2.describe_reserved_instances()

Step 4: Iterate through the list of Reserved Instances and check if any of them have a payment failure

for reserved_instance in reserved_instances['ReservedInstances']:
    if reserved_instance['State'] == 'payment-failed':
        # Perform the remediation action

Step 5: Perform the remediation action, which is to modify the payment method and update the Reserved Instance

# Modify the payment method
ec2.modify_reserved_instances(
    ReservedInstancesIds=[reserved_instance['ReservedInstancesId']],
    ClientToken='string',
    TargetConfigurations=[
        {
            'AvailabilityZone': 'string',
            'InstanceCount': 123,
            'InstanceType': 'string',
            'Platform': 'string'
        },
    ],
    PaymentOption='AllUpfront'
)

# Update the Reserved Instance
ec2.modify_reserved_instances(
    ReservedInstancesIds=[reserved_instance['ReservedInstancesId']],
    ClientToken='string',
    TargetConfigurations=[
        {
            'AvailabilityZone': 'string',
            'InstanceCount': 123,
            'InstanceType': 'string',
            'Platform': 'string'
        },
    ]
)

Step 6: Once the remediation action is performed, verify if the Reserved Instance is updated successfully

# Verify if the Reserved Instance is updated successfully
reserved_instance = ec2.describe_reserved_instances(
    ReservedInstancesIds=[reserved_instance['ReservedInstancesId']]
)
if reserved_instance['ReservedInstances'][0]['State'] != 'payment-failed':
    print('Reserved Instance updated successfully')
else:
    print('Failed to update Reserved Instance')

By following the above steps, you can remediate the misconfiguration “EC2 Reserved Instances Should Not Have Payment Failed” for AWS using python.
