One of the most important features of any computer system is the ability to introduce changes to it seamlessly and in an automatic fashion. When infrastructure is considered, it is especially handy if there is a way to code it. This enables us to replicate it anywhere at any time with a single command. This approach, often abbreviated as Infrastructure-as-Code (IaC), plays a major role in modern applications as it guarantees that all the components are scripted and that no manual work is required to restore them (for example, in the case of disaster recovery).
This section addresses this problem by introducing Azure Resource Manager (ARM) templates, which are JSON files that are used to describe how a service should behave and be configured.
