From 1 to 100k CI/CD Pipeline Jobs in 3 years

From 1 to 100k CI/CD Pipeline Jobs in 3 years

Starting in April 2017 with exactly 1 CI job running inside the on-premise Gitlab-CE installation we raised to more than 50000 pipeline jobs per month at the end of 2019. Why and how did we come to this point? This talk will give you an insight into people and technology and how they both managed it to change the way they work together today and how they are able to deliver services with quality now. Furthermore, I will show you how easy it was to onboard a new young colleague to the team because we already used the GitOps approach. Jump onto a ride through two impressive years and let yourself be inspired about how we did it.
