That is not the only way to think of MSAs, though. In this second installment of my implementing a multi-tenant cloud architecture series, I go step by step through the application layers and tiers, exploring the options for implementing multi-tenancy on each.

The example below is designed based on N-tire architecture and has the following layers: 1. Model is helping to load data for a request while the view is for display purpose. So for example, you have an application that has three clients. As I mentioned before ContextFactory is key component of whole architecture.It construct Entity Framework context (in current example DeviceApiContext) with specific to tenant database A guest user can also read properties of groups they belong to, including group membership, regardless of the Guest users permissions are limited setting.
