Declarative Infrastructure Basics for Systems Admins
summary
Defines declarative vs imperative infrastructure and argues that Terraform becomes the practical standard for writing less code to describe end states, not step-by-step scripts. Describes a Git-centric workflow called GitOps where pull requests are the single source of truth and CI/CD pipelines automatically apply changes, speeding recoveries and scaling. Lists alternatives and integrations: Ansible, Salt, cloud pipelines like AWS CodePipeline and Azure, visual tools like CodeStream, and post‑provisioning config via Puppet.
