It’s not even “infrastructure as code”.
It’s not any single tool.
It’s not about provisioning.
It’s not about deployment.
It’s not about a job description or position.
It’s also not about the cloud, except for the part where deployment and provisioning of infrastructure gets easier to understand for groups of people who historically wouldn’t have touched that part of the business.
It *is* about the collaborative and communicative culture and the tools and process that arise from that culture. Nothing more.
