Database as a Service Reference Architecture Guide: SQL Server 2014
This guide to building the infrastructure for hosting Microsoft® SQL Server® Database as a Service (DBaaS) is not limited to a particular type of hardware. By using the features of SQL Server 2014 and Hyper-V® virtual machines with Microsoft System Center 2012, a hosting service provider can start with very small tenant databases and scale out or scale up to meet the needs of the largest and busiest SQL Server applications. This reference architecture includes hardware, software, system design, and component configuration.
