What's your favorite way to handle config management for cloud stuff

hey ppl, curious about ur experiences managing configs across multiple cloud envs (aws, gcp, azure, etc). are u mainly using tools like terraform or cloudformation, or do u have a diff approach? im particularly interested in strategies for keeping configs consistent and auditable, esp as teams grow and services multiply. what have u found to be the most effective way to avoid drift and ensure deploystuff is repeatable
