You wrote your code. You even tested it. And now, you are eager to git push it. But how can you verify that it really works? In Taboola, we test our code in production! In this article, you will see how every software engineer, even on the first day in the company, can test in production – all thanks to a dedicated Jenkins pipeline job and lots of metrics.

For our release engineers, it was also an unmanageable headache – a “thundering herd” of developers eager to test their features in production. […]

Client facing services are impacted. New information keeps flowing in from different channels and the status of the outage and servers keep changing. How to get the list of the server affected? How to put it all in one place? How to assign responsibility for each? What is the status of each server? How can the internal clients receive ongoing status updates?
