In our previous blog<\/strong>, we discussed serverless architecture<\/a> and AWS lambda functions along with their benefits. <\/p>\n\n\n\n

Here in this blog, we will discuss how we can create a basic lambda function in AWS.<\/p>\n\n\n\n

Our Usecase<\/h2>\n\n\n\n

The lambda function that we are going to use is just a simple Lambda function that will show all the EC2 instances<\/a> in your AWS account whether they are running or not.<\/p>\n\n\n\n

We are not using any kind of filters here but if you want to use filters then you can add commands to your code accordingly.<\/p>\n\n\n\n

This function will only list down all the ec2 instances irrespective of in which AWS region they are.<\/p>\n\n\n\n

Here is the code – <\/strong><\/p>\n\n\n\n

import json\nimport boto3\n\nec2 = boto3.resource('ec2')\n\n\ndef lambda_handler(event, context):\n    \n    instances = ec2.instances.filter()\n    \n    for instance in instances:\n        print(instance.id)\n        \n    return {\n        \"statusCode\": 200,\n        \"body\": True\n        }<\/pre>\n\n\n\n
Runtime – <\/strong>Python 3.7<\/p>\n\n\n\n
And here are the EC2 instances that we are going to list using the Lambda Function – <\/em><\/strong><\/p>\n\n\n\n

Supported Languages<\/h2>\n\n\n\n
We are using Python in our code. But, if you wish then you can create a lambda function using any of the following Supported Languages – <\/p>\n\n\n\n
