1. Log in to the AWS Management Console.
2. Go to the EC2 dashboard.
3. Click on the “Instances” link in the left-hand navigation pane.
4. Select the instance(s) that have scheduled events.
5. Click on the “Actions” button and select “Instance Settings” from the dropdown menu.
6. Click on “Modify Scheduled Events”.
7. In the “Modify Scheduled Events” dialog box, select the scheduled event(s) that you want to modify or delete.
8. To modify the event, update the details as desired and click “Save”. To delete the event, click “Delete”.
9. Repeat steps 4-8 for any additional instances that have scheduled events.

​

1. Open the AWS CLI on your local machine or EC2 instance.
2. Run the following command to list all the scheduled events for your EC2 instances:
   Copy

   Ask AI

   aws ec2 describe-instance-status --include-all-instances --query 'InstanceStatuses[*].Events[*]'
   

3. Identify the scheduled events that are not required or are outdated.
4. To cancel a scheduled event, run the following command:
   Copy

   Ask AI

   aws ec2 cancel-scheduled-instance-termination --instance-id <instance-id> --dry-run
   

   Replace <instance-id> with the ID of the instance for which you want to cancel the scheduled event. Note: The --dry-run option will simulate the command but will not make any changes. Remove this option to execute the command.
5. To modify the scheduled event, run the following command:
   Copy

   Ask AI

   aws ec2 modify-instance-event-attribute --instance-id <instance-id> --instance-event-id <event-id> --not-before <new-time> --dry-run
   

   Replace <instance-id> with the ID of the instance for which you want to modify the scheduled event, <event-id> with the ID of the event, and <new-time> with the new time for the event. Note: The --dry-run option will simulate the command but will not make any changes. Remove this option to execute the command.
6. Repeat steps 4 and 5 for all the scheduled events that need to be remediated.
7. Verify that all the scheduled events have been remediated by running the command in step 2 again.
8. Close the AWS CLI.

1. Import the necessary AWS SDK for Python (Boto3) modules:

import boto3
from botocore.exceptions import ClientError

2. Initialize the EC2 client:

ec2 = boto3.client('ec2')

3. Retrieve the list of EC2 instances using the describe_instances() method:

instances = ec2.describe_instances()

4. Loop through each instance and check if it has any scheduled events using the describe_instance_status() method:

for instance in instances['Reservations']:
    instance_id = instance['Instances'][0]['InstanceId']
    try:
        response = ec2.describe_instance_status(InstanceIds=[instance_id])
        if 'ScheduledEvents' in response['InstanceStatuses'][0]:
            # There are scheduled events for this instance
            print(f"Scheduled events found for instance {instance_id}")
            # Remediate the scheduled events by stopping the instance
            ec2.stop_instances(InstanceIds=[instance_id])
            print(f"Instance {instance_id} stopped successfully")
    except ClientError as e:
        print(f"Error retrieving instance status for {instance_id}: {e}")

5. If the instance has any scheduled events, stop the instance using the stop_instances() method.
6. Verify that the instance has been stopped successfully.
