阅读更多关于 Login to SQL Azure using Windows Authentication

问题 Is it possible to have domain joined SQL Azure servers or Database so that we can use logins from our Active directory using windows Authentication? 回答1: Unfortunatly SQL Azure currently does not support Windows Authentication right now (i.e: integrated security) and it only supports SQL Authentication where user should provide username and password all the time. For more info on SQL Azure security guide lines take a look at the link below: https://azure.microsoft.com/en-us/documentation

问题 I am trying to make sure that all users have been assigned a particular role. Is there any view or SQL query for getting this information? 回答1: The views have changed names but the following should work against SQL Azure select m.name as Member, r.name as Role from sys.database_role_members inner join sys.database_principals m on sys.database_role_members.member_principal_id = m.principal_id inner join sys.database_principals r on sys.database_role_members.role_principal_id = r.principal_id

Multi-tenancy: Individual database per tenant

阅读更多关于 Multi-tenancy: Individual database per tenant

We are developing a multi-tenant application. With respect to architecture, we have designed shared middle tier for business logic and one database per tenant for data persistence. Saying that, business tier will establish set of connections (connection pool) with the database server per tenant. That means application maintain separate connection-pool for each tenant. If we expect around 5000 tenants, then this solution needs high resource utilization (connections between app server and database server per tenant), that leads to performance issue. We have resolved that by keeping common

阅读更多关于 Code First Migrations in SQL Azure - Tables without a clustered index are not supported

I can't seem to get my Code-First Migration to create my SQL Azure database. It keeps complaining about SQL Azure's lack of support for tables without clustered indexes and I cant find a way around to create my database. Note: I'm using CreateDatabaseIfNotExists to create the change tracking tables on the first time database creation because apparently DropCreateDatabaseIfModelChanges doesn't do that for you public partial class IUnityDbContext : DbContext { public IUnityDbContext() : base("Name=IUnityDbContext") { Database.SetInitializer(new CreateDatabaseIfNotExists<IUnityDbContext>()); /

Getting started with Azure storage: Blobs vs Tables vs SQL Azure

阅读更多关于 Getting started with Azure storage: Blobs vs Tables vs SQL Azure

问题 It's quite a topic, blobs vs tables vs SQL , and despite all I read so far I still can't find some proper reasoning on what to use when. We have a multi-tenant SaaS web-application which we are about to move to Azure. We use an SQL Server 2008 database. We store documents and log information that belongs to the documents. Kinda like dropbox does. The forums state that you better use Azure Tables when you are considering "large" objects. We typically store hundreds of documents per user where
