Step 7 - Adding and changing the infrastructure - Local Development

Whats great with Terraform is if you need to add new resources in Azure to support your solution you can edit the Terraform files and just run the steps discussed in Step 1 and it will update the infrastructure based on the combination of the information in your Terraform files and the Terraform state file.

A delta of the changes will be applied so you wont need to rebuild everything (unless you want to) and you could for example add another Function App and update.
