AWS EventBridge Service - process AWS events 

go thru the other videos also and perform hands on of the same.

Thanks Sahab. I have keep the lambda code simple to reduce the complexity. The lambda code as of now is deleting any instance that got created. We can modify this code to ignore certain instance types. Let me know if you are looking for a modified lambda. I can provide you the same.

I'm waiting for your response for above queries.

@@sahabsinghlathwal5956 - this is the code that you can try (not tested, please test it out) import boto3 def lambda_handler(event, context): # Initialize the EC2 client for the N. Virginia region (us-east-1) ec2_client = boto3.client('ec2', region_name='us-east-1') # Get a list of all EC2 instances in the N. Virginia region instances = ec2_client.describe_instances() # Define a list of instance types that are eligible for the AWS Free Tier in us-east-1 free_tier_instance_types = ["t2.micro", "t3.micro", "t3.nano"] for reservation in instances['Reservations']: for instance in reservation['Instances']: # Check if the instance is in a running state if instance['State']['Name'] == 'running': instance_type = instance['InstanceType'] instance_id = instance['InstanceId'] # Check if the instance type is not in the free tier list if instance_type not in free_tier_instance_types: print(f"Terminating instance: {instance_id} (Instance Type: {instance_type})") ec2_client.terminate_instances(InstanceIds=[instance_id]) else: print(f"Skipping instance in Free Tier: {instance_id} (Instance Type: {instance_type})")

Can you plz fix this code and help for another which I asked you for tagging and security group?

yes, but insetad of using events, you will need to create a eventbridge scheduler. This scheduler can trigger a lambda function as per your schedule. That lambda will fetch all the ec2 instances in your account and stop or restart them as per your requirement.

In the comments, i am not able to paste screenshot for the scheduler.

I really need that scheduler... I want to terminate the instance at 1am and then start it at 6am.. I want to do it repeatedly... Hope you can help me with that

@@tompatrickhankz2244 how comfortable r u with AWS ?? And with writing a AWS lambda ??

@@AWSTrainingByGauravAgrawal Am not that comfortable but i can try.. With help of a video

yeah, here is the aws doc - aws.amazon.com/lambda/ - Also i will be creating an entire course, so please feel free to subscribe to the channel.
