"I can't reproduce it," "we'll need to add logs," "we can't test that in staging," "it seems to have been broken for a while," "it works locally," ...
If you hear these phrases regularly, this talk is for you.
If you often feel like you're a step behind on bugs, this talk is also for you.

During this talk, I introduce the concept of observability and how it can help developers always stay ahead, increase application quality, and thus have more time to add value!
I then present the concrete methods and tools we have implemented at WP Media to maintain and monitor our products, which are used on over 4 million websites, and our services, with daily production deployments and several thousand requests per second; all managed by only a dozen developers.

I briefly revisit the basics, but enhanced:
- Standardized logs that anyone can add,
- On-demand test environments

And I discuss more advanced methods and tools to simplify their implementation:
- Error & Performance tracking, Tracing, and technical alerts with Sentry
- Functional alerts and data observability with Metabase
- Canary releases
- Shadow releases
- Health Probes

If these techniques are unfamiliar to you, if you have difficulty implementing them, or if you simply want a refresher, this talk is a great opportunity to hear about practical experiences and tips on observability!

Target audience:
This talk is designed mostly for developers, product owners, scrum masters, team leaders, and engineering managers with a first experience in running and maintaining a backend service, especially in small/mid-size companies.
