✑ 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 Requirements

Litware identifies the following resiliency requirements:

✑ Once migrated to Azure, DB1 and DB2 must meet the following requirements:

Planned Changes and Requirements. Security and Compliance Requirements

Litware 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.

Box 1: 3

Scenario: App1 must meet the following requirements:

✑ Be hosted in an Azure region that supports availability zones.

✑ Maintain availability if two availability zones in the local Azure region fail.

A host group is a resource that represents a collection of dedicated hosts. You create a host group in a region and an availability zone, and add hosts to it.

Use Availability Zones for fault isolation

Availability zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. A host group is created in a single availability zone. Once created, all hosts will be placed within that zone. To achieve high availability across zones, you need to create multiple host groups (one per zone) and spread your hosts accordingly.

Box 2: 1

Scenario: App1 must meet the following requirements:

✑ Be hosted on Azure virtual machines that support automatic scaling.

An Azure virtual machine scale set can automatically increase or decrease the number of VM instances that run your application. This automated and elastic behavior reduces the management overhead to monitor and optimize the performance of your application.
