# The automation paradox
The point of automation is to reduce the manual workload.<br/>
It's goals are also to maintain consistency and reliability of infrastructure and processes.
The issue:
- For every automation one puts in place, a _system_ is created.<br/>
Such system is the automation itself of the set of tools used to create it.
- A system needs configuration and maintenance.
- One relies on systems to maintain other systems.
- Complex systems trend toward _brittle_ and _expensive_.<br/>
Especially true when one uses imperative runbooks.<br/>
Google [_Software crisis_][software crisis] for more info.
- The need to manage such complexity gave birth to a whole cottage industry.<br/>
This includes tools and specific job titles (i.e. _DevOps_, _SRE_).
- The tools one choses to implement one's system need to be consistent and reliable.<br/>
Should they not be, their issues defeat the whole purpose of what one is trying to automate.
Possible solutions:
- Move from imperative to declarative (desired state) where one can.<br/>
Check out [the _GitOps_ approach][gitops].
- Apply the KISS approach where possible.<br/>
Make it so that is simple to maintain, not necessarily simple for the sake of simplicity.
- Focus on the tools that most allow one to simplify the automation.<br/>
Dependent on the final goals.
- Limit abstractions.<br/>
