Hey folks!

I bet you love troubleshooting bugs during an emergency production fix. Right?
Well, if you prefer the peace of mind that comes with a well-tested application, this session might be for you!

Abstract:

A bug found in production can be up to 640 times more costly than one identified locally.

This session will delve into the alarming cost differentials associated with bugs found in production, compared to those identified during local development. Using real-world case studies and industry insights, we'll explore the financial and operational implications of not addressing bugs until they appear in live environments.

The session will provide effective strategies that go beyond the traditional unit and integration testing. From leveraging advanced debugging tools to using AI to replay production traffic locally, attendees will gain actionable insights into ensuring 0 production bugs. We will also discuss the role of continuous testing and how developers can shorten the feedback loop with minimal effort.

Join us to learn practical strategies that reduce the financial impact of production bugs and double the speed of feature releases. Arm yourself with the knowledge to identify and address issues before they escalate.

Hello everyone!

The main entry of most of our backend applications nowadays is some sort of HTTP API. As such, they are a critical part of your design.
Join us to learn how to manage them efficiently.

Abstract:

When you publish your first HTTP API, you’re more focused on short-term issues than planning for the future. However, chances are you’ll be successful, and you’ll “hit the wall”. How do you evolve your API without breaking the contract with your existing users?

In this talk, I’ll first show you some tips and tricks to achieve that: moving your endpoints, deprecating them, monitoring who’s using them, and letting users know about the new endpoints. The talk is demo-based, and I’ll use the Apache APISIX project for it.
