A reusable building block is a modular automation component designed for incorporation into multiple processes. It turns a one-off script into a repeatable asset that supports phased automation and reduces duplicated effort. section 2.0 section 1.2
Design the automation around four questions:
- Goal: what must the automation accomplish? section 1.2
- Trigger: what initiates the actions? section 1.2
- Actions: which steps produce the intended result? section 1.2
- Maintainability: what will it take to maintain the overall automation and each building block? section 1.2
Log cleanup as a reusable component
A web server fills its drives with logs that must remain available for security audits. A phased automation can find logs older than 30 days, compress them, and move them to long-term storage. Turning that cleanup script into a reusable building block makes the capability available to other automations; PowerShell functions can then be stored in a module for reuse. section 2.0 section 1.2
