Multi Tenant architecture with Docker .NET 8

Hi everyone, I'm making an app that already have an identity service using Asp .Net Core Identity, now I have to make tenants to each user so they have dedicated services and a faster response from the back end, making a good UX. I'm wondering what is the best approach to multi tenants, how to build it with .NET and where can I find more information about it to learn. I did two diagrams of possible ways that I want it to be (they look terrible), but I don't know how to implement them or where to find the information to learn it to select one of them based in what the app needs. Any information regarding this subject would be appreciated, I just need resources to learn and a path to go, thank you!
