lets administrators leave behind manual processes and avoid the drudgery of entering fields into a web form. Instead, they use configuration files to manage every component of the datacenter, from bare Infrastructure as Code Infrastructure as code grew from the need to scale up quickly in the cloud. Amazon Web Services launched its Elastic Compute Cloud (EC2) in 2006, letting clients scale their infrastructure some customization. To render the YAML output for the dev environ- ment, run: $ kubectl apply -k apps/myapp/overlays/dev The preceding command takes the base YAML and overlays what’s in the dev directory

With your application’s declarations versioned in Git, you have a single source of truth. Your apps can then be easily deployed and rolled back to and from Kubernetes. And even more importantly, when Increased Consistency and Standardization Because GitOps provides one model for making infrastructure, apps and add on changes, you have consistent end to end workflows across your entire organization.
