Building a resilient input handling with Parser

Author: Ran Isenberg

When building applications with AWS Lambda it is critical to verify the data structure and validate the input due to the multiple different sources that can trigger them. In this session Ran Isenberg (CyberArk) will present one of the interesting features of AWS Lambda Powertools for python: the parser.

In this session you will learn how to increase code quality, extensibility and testability, boost you productivity and ship rock solid apps to production.

Author: Ran Isenberg

A deep dive in the Feature Flags feature along with tips and tricks.

Level Up Your CI/CD With Smart AWS Feature Flags

Author: Ran Isenberg

Feature flags can improve your CI/CD process by enabling capabilities otherwise not possible, thus making them an enabler of DevOps and a crucial part of continuous integration. Partial rollouts, A/B testing, and the ability to quickly change a configuration without redeploying code are advantages you gain by using features flags.

In this talk, you will learn the added value of using feature flags as part of your CI/CD process and how AWS Lambda Powertools can help with that.


Introduction to Lambda Powertools

Author: Michael Walmsley

This repo contains documentation for a live coding workshop for the AWS Programming and Tools Meetup in Melbourne. The workshop will start with the SAM Cli "Hello World" example API project.

Throughout the labs we will introduce each of the AWS Lambda Powertools Core utilities to showcase how simple they are to use and adopt for all your projects, and how powerful they are at bringing you closer to the Well Architected Serverless Lens.

Complete Lambda Handler Cookbook

Author: Ran Isenberg

This repository provides a working, deployable, open source based, AWS Lambda handler and AWS CDK Python code.

This handler embodies Serverless best practices and has all the bells and whistles for a proper production ready handler. It uses many of the AWS Lambda Powertools utilities for Python.

Serverless Transactional Message App

Author: Santiago Garcia Arango

This repository contains a well documented example of a Transactional Messages App that illustrates how to use Lambda PowerTools to process SQS messages in batches (with IaC on top of CDK).

It uses LambdaPowerTools Logger, Tracing, DataClasses and includes unit tests.
