You pay only for the compute time you consume - there is no charge when your code is not running. How AWS Lambda Works? The block triggered. Step 3: AWS Lambda which has the upload code and the event details on which the trigger has occurred. For example, event from Amazon S3, Amazon API Gateway, Dynamo dB, Amazon SNS, Amazon
