Resource Group Deployments (RG)

RG logical collection
Resources can only exists in one RG
RG can not change name, renamed
RG can have many different resources
RG can have resources from different regions

Creating RG

Should share same lifecycle, (Deploy, update, delete together), if one resource, a database needs a different cycle, then use a different RG
A resource can only be in one RG
Add/remove to RG at any time
Can move a resource from one RG to another
A RG can contain resources from many regions
A RG can be used to scope access for admin
A resource can connect/call/talk to resources in a another RG, ie app->db connection

RM Locks

RM locks, is used to prevent a delete or removal
Can lock subscription, RG or resource
Locks use inheritance
Two types, Read only (no changes) and Delete
Only owner and user access admin role can create/delete locks

Moving Resources

Move resources to a new sub or resource to a new rg in the same sub.

When moving = source/target is locked, write/delete are blocked on the rg, no add, update or del in those rg’s. The resources are still functioning as normal.

Read this before move:
