Although cloud storage fabrics are very cool, a lot of multi-tenant applications will be build against a database. Based on some work we did on our super famous sample application LitwareHR :) , we just released a blueprint providing guidance on writing a SQL Server based, single instance, multi-tenant data access layer. (thanks Michael for the blueprint framework)
Here is a short video introducing the MTDA blueprint. Interviewer: Michael, interviewee: Eugenio
