How to build and configure AWS Step Functions to orchestrate AWS Lambda functions and handle decision logic.

AWS Step functions allow developers to offload application orchestration into a fully managed AWS service. In this tutorial, I show you how to use AWS Step Functions to pass input into your lambda, and use your lambda's output to decide next steps in your Step Function's decision logic. I start out by creating the step function and attaching the required IAM role. From there I integrate with Lambda and fire some test events to verify everything is connected.

On “Need to run a aws lambda function which takes more than 15 minutes to complete?”

…is used when your task is singular but has a long-running execution time and/or you have heavy hardware requirements. The idea is that you would create a script that executes your long process and put it into a docker container that's hosted in Fargate. Meaning no limits to execution time and access to powerful hardware (How to create a Fat Lambda link to this video) Step Function strategy A Step Function strategy is used to break down your entire process into smaller steps. Usually, a step function strategy would work for you if your process could have lots of miniature stages linked together instead of a big colossal job attempting to do everything simultaneously. Bear in mind that a "Fat Lambd…
