In this episode of the Azure Government video series, Steve Michelotti talks with Rafat Sarosh, Program Manager on the Cosmos DB team, about Cosmos DB on Azure Government. This article explains how to combine access control with partitioned collections, so that a user can only access their own documents in a Xamarin.Forms application. Azure Cosmos DB provides built-in Azure role-based access control (Azure RBAC) for common management scenarios in Azure Cosmos DB. You need to install the latest version of Azure CLI on your Windows VM. Therefore, the document query contains a Where clause that applies a filtering predicate to the query against the document collection. A permission resource provides access to a security token that the user requires when attempting to access a resource such as a document. The resource token is sent with each request to directly access a resource, and indicates that read/write access to the authenticated users' partitioned collection is granted. Retrieving documents that only belong to the authenticated user can be achieved by creating a document query that includes the user's id as a partition key, and is demonstrated in the following code example: The query asynchronously retrieves all the documents belonging to the authenticated user, from the specified collection, and places them in a List collection for display. This section shows how to call Azure Resource Manager using an access token for the Windows VM system-assigned managed identity. Create Cosmos DB in Azure. Azure Cosmos DB is a fully managed service that enables you to offload the administrative burdens of operating and scaling distributed databases to Azure, so you don’t have to worry about managing VMs, hardware provisioning, setup and configuration, capacity, … The multiple Cosmos DB Users are created dynamically by the broker, the first time an Azure AD B2C User requests a set of Resource Tokens. Tag: Cosmos DB. 5. Azure Cosmos DB itself is a multi-tenant PaaS offering on Microsoft Azure. However, you can use a system-assigned managed identity to retrieve a Cosmos DB access key from Resource Manager, and use the key to access Cosmos DB. Create a Cosmos DB account that will use access control. If you need to create a virtual machine for this tutorial, you can follow the article titled. For more information about Cosmos DB partitioning, see How to partition and scale in Azure Cosmos DB. In the Azure portal, navigate to Virtual Machines, go to your Windows virtual machine, then from the Overview page click Connect at the top. You usually won't want to use the primary credentials of the database, but instead to set up a specialised identity. So, the connection string format is: Data model. Next, add a data collection in the Cosmos DB account that you can query in later steps. The resourcetoken API uses the access token to request the user's identity from Facebook, which in turn is used to request a resource token from Cosmos DB. Every request to the Cosmos DB has different needs for resources. The process for configuring the Xamarin.Forms sample application is as follows: The sample application initiates the login process by redirecting a browser to an identity provider URL, as demonstrated in the following example code: This causes an OAuth authentication flow to be initiated between Azure App Service and Facebook, which displays the Facebook login page: The login can be cancelled by pressing the Cancel button on iOS or by pressing the Back button on Android, in which case the user remains unauthenticated and the identity provider user interface is removed from the screen. Assign the DocumentDB Account Contributor role if you want to get read/write keys for the account, or assign the Cosmos DB Account Reader Role role if you want to get read-only keys for the account. After the authentication flow completes, the Xamarin.Forms application receives an access token. Specifying the user's identity as a partition key ensures that a partitioned collection can only store documents for that user. This can be accomplished by selecting the Facebook identity provider, and entering the App ID and App Secret values from the Facebook app settings on the Facebook Developer Center. For more information, see, Create a Cosmos DB account. Met Azure Cosmos DB worden uw gegevens transparant gerepliceerd in alle regio's die aan uw Azure Cosmos DB-account zijn gekoppeld.
