Programmable infrastructures allow you to manage on-premises and cloud resources through code instead of with the management platforms and manual methods traditionally used by IT teams. An infrastructure captured in code is simpler to manage, can be replicated or altered with greater accuracy, and benefits from all sorts of automation. It can also have changes to it implemented and tracked with the version control methods customarily used in software development. Programmable infrastructures become particularly interesting when you provision workloads on a hybrid cloud environment that consists of on-premises and public cloud resources. Two services— AWS CloudFormation and Terraform by HashiCorp —allow you to express your infrastructure resources as code and manage them programmatically.
