Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you are planning to deploy a 3rd party tool from Azure Market place.
Please note that SMEs here may have expertise over Azure Products, but that may not be the same case for Azure market place resources.
With that said,
- Are you sure the RG created by this 3rd party service allows you to move or deploy resources other than those that are created/managed by the service itself?
- i.e., is it partially managed or completely managed?
- If the resource allows VNET Peering, I would suggest you consider VNET Peering instead of deploying Azure resources into this partially managed/completely managed VNET
- This makes sense as if you want to remove the 3rd party service, you could simply remove the VNET Peering and keep the Azure resources intact (non-destructive)
- However, if the Azure resources are in the same managed VNET, there may be some restrictions imposed by the 3rd party service
- Please check with the 3rd party's documentations/recommendations on deploying other resources in the same VNET / RG.
Hope this helps.
Cheers,
Kapil
