Is Lighthouse usable between 4 tennants and 1 21vianet tennant

@Michael Paul Thibodeaux Thank you for your query.

Resurfacing the information shared as comment , so it helps the broader community users.

If the scenario is that you have subscriptions from 4 different tenants and want to access them from 1 21vianet tenant ? Yes you could utilize Azure Lighthouse here.

Hope this information helps. Please let us know if you have any further queries

hi,
To follow up.
I have a customer in Azure China, hosted by 21vianet.
Can the customer in their China subscription use Lighthouse to give access to my Azure service provider tenant?
I thought Azure China was physically separate to Azure?

@bharathn-msft is your statement still true in 2022

We have our main tenant in germany from which we manage a tenant in Switzerland and would also want to manage the 21Vianet tenant in China.

Do you know about any constaints / limitations as 21Vianet (Gallatin) does not have feature parity with AZ global.
Is there a KB that would guide us on seting up lighthouse with 21Vianet ?

thx a lot

i really think @bharathn-msft is right. Lighthouse used the Azure backbone. There is no direct connectivity between Azure (global) and Azure China.
