Disclaimer
The opinions expressed in this presentation and on the following slides are solely those of
the presenter and not necessarily those of Scania as a whole.
We at infra need to be an enabler for developers. Enable automatic deployments
and roll-backs.
Creating tools/dashboards with relevant KPI’s so that the developer can fast and
easily see the consequences of a deployment.
