Identity EnvironmentThe network contains an Active Directory forest named Litware.com that is linked to an Azure Active Directory (Azure AD) tenant named Litware.com. All users have Azure Active Directory Premium P2 licenses.Litware has a second Azure AD tenant named dev.Litware.com that is used as a development environment.The Litware.com tenant has a conditional acсess policy named capolicy1. Capolicy1 requires that when users manage the Azure subscription for a production environment by using the Azure portal,they must connect from a hybrid Azure AD-joined device.Existing Environment. Azure EnvironmentLitware has 10 Azure subscriptions that are linked to the Litware.com tenant and five Azure subscriptions that are linked to the dev.Litware.com tenant. All the subscriptions are in an Enterprise Agreement (EA).The Litware.com tenant contains a custom Azure role-based access control (Azure RBAC) role named Role1 that grants the DataActions read permission to the blobs and files in Azure Storage.Existing Environment. On-premises EnvironmentThe on-premises network of Litware contains the resources shown in the following table.Existing Environment. Network EnvironmentLitware has ExpressRoute connectivity to Azure.Planned Changes and Requirements. Planned ChangesLitware plans to implement the following changes:Migrate DB1 and DB2 to Azure.Migrate App1 to Azure virtual machines.Deploy the Azure virtual machines that will host App1 to Azure dedicated hosts.Planned Changes and Requirements. Authentication and Authorization RequirementsLitware identifies the following authentication and authorization requirements:Users that manage the production environment by using the Azure portal must connect from a hybrid Azure AD-joined device and authenticate by using Azure Multi-Factor Authentication (MFA).The Network Contributor built-in RBAC role must be used to grant permission to all the virtual networks in all the Azure subscriptions.To access the resources in Azure, App1 must use the managed identity of the virtual machines that will host the app.Role1 must be used to assign permissions to the storage accounts of all the Azure subscriptions.RBAC roles must be applied at the highest level possible.Planned Changes and Requirements. Resiliency RequirementsLitware identifies the following resiliency requirements:Once migrated to Azure, DB1 and DB2 must meet the following requirements: - Maintain availability if two availability zones in the local Azure region fail. - Fail over automatically. - Minimize I/O latency.App1 must meet the following requirements: - Be hosted in an Azure region that supports availability zones. - Be hosted on Azure virtual machines that support automatic scaling. - Maintain availability if two availability zones in the local Azure region fail.Planned Changes and Requirements. Security and Compliance RequirementsLitware identifies the following security and compliance requirements:Once App1 is migrated to Azure, you must ensure that new data can be written to the app, and the modification of new and existing data is prevented for a period of three years.On-premises users and services must be able to access the Azure Storage account that will host the data in App1.Access to the public endpoint of the Azure Storage account that will host the App1 data must be prevented.All Azure SQL databases in the production environment must have Transparent Data Encryption (TDE) enabled.App1 must not share physical hardware with other workloads.Planned Changes and Requirements. Business RequirementsLitware identifies the following business requirements:Minimize administrative effort.Minimize costs.You need to implement the Azure RBAC role assignments for the Network Contributor role.
