Observability for Application Deployments

Presented
React Universe Meetup
Speaker
Pepijn Senders
Principal Engineer
@
HelloFresh

When your users complain that your app is slow, how do you pinpoint exactly what’s wrong, and how to fix it?

In this talk , Pepijn Sanders demystifies observability for application deployments. You'll explore how to precisely measure performance from end-to-end, tracing slowdowns from the user's device to backend services, and discover why latency can vary dramatically across regions, even at the speed of light.

Pepijn shares HelloFresh’s real-world experiences, explaining how they used advanced observability to reduce global latency, slash load times by 50%, and cut API timeouts by 47%. Expect deep technical insights, practical examples, and actionable strategies for implementing effective observability to diagnose, debug, and optimize your own application deployments.
