Ever wonder why some teams intentionally break their own systems? Welcome to the world of chaos engineering — a practice that's not just for Netflix-scale infrastructure, but for any team that wants to build resilient, reliable applications. In this session, we'll demystify chaos engineering and explain why intentionally breaking things is actually the smart move. You'll learn what chaos engineering really is (in plain English, no buzzwords), why waiting for production failures is a terrible strategy, how to start experimenting with controlled failure locally, before it happens in the wild, real-world examples of chaos experiments that catch bugs you'd never find in traditional testing, and tools and techniques to get started without blowing up your infrastructure. Through practical demos using LocalStack's cloud emulation and chaos engineering tools, we'll simulate failures like network latency, service outages, and resource exhaustion right from your laptop. If you've ever said "it worked on my machine" only to watch it crash in production, this talk is for you—let's break things intentionally so they don't break unexpectedly.

LocalStack Applications in Developer Hub provides sample templates to help LocalStack users adopt real-world scenarios to rapidly and conveniently create, configure, and deploy applications locally.
Getting started with Step-up-authentication demo
In this demo, we will setup a step-up authentication workflow for a higher level of security, deployed using Cloud Development Kit on LocalStack

Running your Spring Boot app on AWS for production is common, but testing there can be slow and costly. In this video, we’ll show you how to speed up development using LocalStack. By provisioning your infrastructure with Terraform, you can easily switch to local testing in just three steps: configure your dev environment variables, start LocalStack in Docker, and run your IaC files. Get faster feedback and reduce costs by testing locally with LocalStack!

In this live session, WireMock CTO Tom Akehurst will introduce hybrid API simulation (local + cloud) with WireMock Runner. Tom will explain why we built Runner, how developers are using it today, and how it fits into modern dev and test workflows - such as simulating APIs during testing, prototyping, and AI-native development.
