Code structure examples

Terraform code structures
These examples are showing AWS provider but the majority of principles shown in the examples can be applied to other public cloud providers as well as other kinds of providers (DNS, DB, Monitoring, etc)
Type
Description
Readiness
​small​
Few resources, no external dependencies. Single AWS account. Single region. Single environment.
Yes
​medium​
Several AWS accounts and environments, off-the-shelf infrastructure modules using Terraform.
Yes
​large​
Many AWS accounts, many regions, urgent need to reduce copy-paste, custom infrastructure modules, heavy usage of compositions. Using Terraform.
WIP
very-large
Several providers (AWS, GCP, Azure). Multi-cloud deployments. Using Terraform.
