In the cloud-native world, infrastructure is code, often written using declarative languages such as YAML. Instead of building virtual machines and networking by clicking in Web forms, you put together a template that can be accessed by a script to deploy the features it describes: machines, applications, services, networking. You can write a template once, sharing it with colleagues or even managing it in your GitHub repository, pushing out a new infrastructure automatically at the end of each CI/CD (continuous integration/continuous development) build.
