In the future we’ll extend the duration limit of Lambda functions beyond 60 seconds, allowing you to do long-running jobs when your intent really is to keep things running. It refers to the fact that when a container is created, AWS needs extra time to load the code and set up the environment versus just reusing an existing container.. they use a version of the AWS SDK .

Unfortunately, Lambda does not have native support for PHP and it has not been that easy to run PHP applications here. In nodejs, a Lambda function can complete in one of three ways: There’s also effectively a fourth way to exit – by crashing or calling process.exit().
