First of all, the default time AWS will let Lambda functions run is 3 seconds, so we need to extend that. This is untrue. AWS Lambda tries to reuse the execution context again if the Lambda function is invoked taking lesser time. If you recall in addition to a callback, Lambda takes two parameters: event and context. Instead of using api gateway you can just use aws sdk to call invoke() which will invoke your lambda function. Therefore, make sure to configure the Task timeout to be equal to the Lambda's timeout. You only have to manage the actual code you want to run and the rest is taken care of by the cloud provider. invocations (count). AWS Lambda : AWS Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you. An example of a Lambda function use case might be that you want AWS to run a simple script for you. With the typical lambda configured to timeout well before 30 seconds, the AWS-SDK default options translate to “succeed, or just wait out the life of the lambda”. If you're not familiar with Lambda, it's a new AWS compute service that manages the AWS resources for us. Firstly, our lambda function will invoke AWS CloudWatch event or from API Gateway. Issue: I have an AWS Lambda function that is expected to run for a few minutes and it has a timeout of 4 minutes. This is the simplest but more strict option via the Invoke Function action - you tell us which function you want us to invoke and we'll provide the data to invoke it.
