The traditional deploy-and-test cycles for Java applications running in public clouds can become slow and tedious, where developers are often facing several minutes of idle time between deployment, testing and debugging.

In this session, I’ll show you in a live coding session how to bring AWS to your laptop with Localstack. Localstack allows you to run AWS services locally, reducing the develop and test cycle from minutes to seconds. It also allows you to validate your Infrastructure as Code changes instantly, and combined with TestContainers allows you to run integration tests seamlessly inside your CI/CD pipelines. No more waiting on slow deployments or paying for test environments just to find out something doesn’t work.

You’ll walk away with practical patterns for local-first testing, strategies for embedding LocalStack in your pipelines, and the confidence to ship infrastructure changes faster.
