AZ104 – PT2 – 1-5 – Case Study

WebMagic is an online training provider.

Existing Environment

The existing environment for WebMagic currently consists of the following resources in their On-premise data center. These resources are used for the daily operations for the various business units:

• File servers – Windows Server 2016
• Domain controllers – Windows Server 2012 R2
• Microsoft SQL Server servers – Windows Server 2016

The domain controllers support an Active Directory forest named WebMagic.com.

WebMagic also supports a web-based application called WebMagic-app. Users across the world use this application. The application consists of the following tiers:

• A SQL database
• A web front end
• A processing middle tier

Following are the planned changes for WebMagic

• Migrate all WebMagic-app tiers to Azure.
• Each tier would consist of 5 virtual machines.
• Users would access the web application tier using HTTPS only.
• Move the existing documents to Azure Blob storage using the internet.

Following are the technical requirements for WebMagic

• All Virtual machines hosted in Azure should be backed-up.
• The documents in Azure BLOB storage should be stored in an archive storage tier.
• Azure AD should be used along with the on-premise Active Directory.
• Users should be synched between Azure AD and the on-premise Active Directory.
• User passwords or hashes should not be stored in Azure.
• When users joined their own devices to Azure AD, they need to use a phone verification method to verify their identity.
• Administrative effort should be minimized whenever possible, a mobile phone to verify their identity.
• There should be a pilot group so that the testing of devices joining Azure AD can be carried out.
• A new user called WebMagic-admin would be set as a service administrator of the Azure subscription.
