Gurs-7768, Thanks for the update. Adding to TakahitoIwasa suggestions to share additional info.
As posted by ElliottHamai-6773 (from App Service product team) on this discussion thread.
“We recently pushed out a change to the WordPress on App Service creation experience which simplifies the configuration for WordPress. In the old experience you needed to specify database information, but in the new experience that is no longer required. Instead, we now choose a configuration that we know will work well for you to run WordPress with the least amount of issues.”
The reasoning for this change was to enable production scenarios and make the experience simpler to get started. I completely understand about the cost effects here, that said, you may try the following options post creation of your resources:
• The App Service plan can be scaled down to a different SKU | post creation.
• The WebApp can be moved to a different App Service Plan | post creation.
• You may generate an ARM template from your WordPress deployment and further tweak it to fit your needs.
Please be assured that we have also relayed your feedback to our product engineering internally.
Thanks for your cooperation and patience!
