The "everything as code" approach treats a Git repository as a contract that fully describes a system's desired state, much like a blueprint for a motorcycle.
Git is used as the foundation for collaboration and change management because it provides versioning, peer reviews, and asynchronous approvals for all system changes.
CI/CD tools like Jenkins act as gatekeepers that run automated checks for static analysis, security, and operational readiness on every proposed change before deployment.
Reconciliation agents like ArgoCD continuously compare the desired state in Git with the actual production state and automatically align them, extending to multi-region topology.
The evolution from simple mainframes to complex, multi-cloud Kubernetes environments has made managing systems by hand impossible, necessitating automation and "as code" practices.
A practical demonstration shows how to define a CI pipeline and create monitoring dashboards using simple configuration files committed to a Git repository.
This demo illustrates how to automatically generate technical documentation, diagrams, and even presentation slides from Markdown and other simple text-based formats.
A live example shows how merging a pull request triggers a deployment via ArgoCD and how an incident is quickly resolved by simply reverting the commit in Git.
GitOps provides cheap disaster recovery, embedded security, and a scalable way to manage complexity by adhering to declarative, version-controlled, and continuously reconciled principles.
