7 - Additional Regions

Additional regions are supported. The custom can add up to 10 regions using the out of the box module.

If you need to scale beyond 10 regions, that can be accommodated by adding additional built in replacements here

To add an additional regions, the process is copy -> paste -> update.

The settings are slightly different depending on the chosen networking type:

1. Find, copy, paste and update the following settings by searching for the keys and copying the line or block.

   Setting Type	Parent block(s)	Key	Action	Count	Notes
   line	custom_replacements > names	connectivity_hub_<region>_resource_group_name	Copy, Paste, and Update	1	<region> is the relevant region (e.g. primary)

For example, to add a third region you would copy and paste all the primary configuration. Then replace the <region> primary with tertiary and starter_location_01 with starter_location_03.
