Automation is key!
There's a saying that IT professionals tend to be lazier than others - any maybe there's some truth to it. But is it really a bad character trait? Not necessarily.
Lazy developers and admins automate. They don't repeat the same set of tasks over and over again, but instead come up with an idea to make their lifes easier and more convenient ;-)
As even ZERO GmbH is not safe from lazy developers, we have automated some processes in our IT - including the setup of various software components for our #AMPS nodes and the associated IT infrastructure, such as #VPN and #DNS setup.
This saves us a huge amount of time. A quarter of an hour of manual labour can become a few seconds of waiting time and we have time for more interesting tasks :-)
We mainly use the Ansible configuration tool, which we like because it works without an additional daemon on the target and via a simple SSH interface.
