Benefits of ARM

There may be situations where you would like to rapidly deploy infrastructure in a consistent and automated manner. ARM is a great tool for enabling this capability as well as several other benefits, as listed here, which are sure to pique your interest:

• Consistency: ARM templates ensure that deployments are consistent and repeatable across different environments (development, testing, and production) and subscriptions, reducing the chances of configuration drift. Your deployments are standardized because they are predefined in a template file, and as a result, risk is reduced too.
• Declarative: With ARM templates, you define the desired end state of your infrastructure using JSON. This declarative approach focuses on what resources you require, rather than specifying the sequence in which they need to be created or deployed.
• Idempotence: ARM templates are idempotent, meaning you can run them multiple times, and the result will be the same desired state...
