Why did we build this?

First some history…

With the original ALZ Terraform (caf-enterprise-scale) module we always had the concept of a library, but it was built into the module. In the early days of alzlib, we also embedded the library into the Go module.

This tight coupling made it difficult to update the library without updating the module - it was impossible to seperate module feature updates from library updates. If you wanted the most up to date policies, then you also had to take the latest module feature updates too.

We therefore decoupled the library from the module and created this repository. Because the library is now a seperate entity, it can be updated and version controlled independently of the module. It also has the added benefit of being able to be consumed by other clients, not just Terraform.

• Consumable: The library can be consumed by any client
• Extensible: The library can be extended by anyone
• Quality: The library can be tested and validated independently of the consumer
• Versioning: The library can be versioned independently of the consumer
