For the moment the general topic

Answer 1

I have a blog post describing my proposal of how to go about making a multi tenant SAAS web application using Django. Multi-tenancy here means that when user registers, they have their sub-domain. To recap:

• All tenants share one database, but each has their own schemas. Imagine you have website abc.com and someone registered a xyz tenant so that they access their page through xyz.abc.com, then for a tenant xyz you have a separate schema containing all the tables thus encapsulating data related only to xyz tenant. There are other ways, like having one database and one schema for all, or having even separate databases. But schemas approach is the best trade-off. The django-tenants library's documentation contains more detailed info if you are interested
• Use django-tenants library to abstract away work with tenants. When someone accesses xyz.abc.com, you need to know that xyz is the tenant and that you should use xyz schema. django-tenants library does this for you so on each request you can obtain the tenant object by simply doing current_tenant = request.tenant
• You need to differentiate between shared tables and tenant-specific tables. For example, having table with list of orders is tenant-specific. Every tenant might have their own database containing all their orders. This table should be inside xyz schema. At the same time, you will have some core Django tables, like user. The data can be shared, for example, to disallow two users registering with the same email.
• You need to configure your DNS to catch a wildcard expression *.abc.com, for which you can add an A record inside your CPanel with *.abc.com linking to the IP of your server
