<h3>Map Resource Dependencies</h3>
|
|
<p>
|
|
Understand how a minor change could have potential cascading effects
|
|
across an infrastructure before executing that change. Terraform
|
|
builds a dependency graph from the configurations, and walks this
|
|
graph to generate plans, refresh state, and more.

<h3>Separation of Plan & Apply</h3>
|
|
<p>
|
|
Separating plans and applies reduces mistakes and uncertainty at
|
|
scale. Plans show operators what would happen, applies execute
|
|
changes.

providers. Launch a server from one cloud provider, add a DNS entry

means things happen in the right order.</p>
