I used ansible for building simple logging appliance (something like Elasticsearch + Dashboards + other tooling) and I found it very difficult to reason with specifically python code snippets within YAML.

Switched to Pyinfra and the difference is day and night. You write python code you can organise your stuff into functions, classes and whatever you like and then instantiate them as you like. Highly reusable configuration.

You have full pwoer such as you can call boto to fetch the list of servers to target, filter base on tags and what not. Only sky is the limit because it is NOT a DSL (or YAML) rather full blow real python.
