Using Node, and no framework currently? Try lambda-local.
You can use metrics to aid debugging by adding them to your dashboards that we talked about earlier. It’s also possible to add custom metrics, and there are many libraries and tools (e.g. node, python, etc) which can help you do this.
Using Serverless Framework? Try Serverless Offline.
Want to emulate AWS environments? Try docker-lambda.
