Background
VanArsdel, Ltd. builds skyscrapers, subways, and bridges. VanArsdel is a leader in using technology to do
construction better.
Overview
VanArsdel employees are able to use their own mobile devices for work activities because the company
recognizes that this usage enables employee productivity. Employees also access Software as a Service
(SaaS) applications, including DocuSign, Dropbox, and Citrix. The company continues to evaluate and adopt
more SaaS applications for its business. VanArsdel uses Azure Active Directory (AD) to authenticate its
employees, as well as Multi-Factor Authentication (MFA). Management enjoys the ease with which MFA can be
enabled and disabled for employees who use cloud-based services. VanArsdel’s on-premises directory
contains a single forest.
Helpdesk:
VanArsdel creates a helpdesk group to assist its employees. The company sends email messages to all its
employees about the helpdesk group and how to contact it. Configuring employee access for SaaS applications
is often a time-consuming task. It is not always obvious to the helpdesk group which users should be given
access to which SaaS applications. The helpdesk group must respond to many phone calls and email
messages to solve this problem, which takes up valuable time. The helpdesk group is unable to meet the needs
of VanArsdel’s employees.
However, many employees do not work with the helpdesk group to solve their access problems. Instead, these
employees contact their co-workers or managers to find someone who can help them. Also, new employees
are not always told to contact the helpdesk group for access problems. Some employees report that they
cannot see all the applications in the Access Panel that they have access to. Some employees report that they
must re-enter their passwords when they access cloud applications, even though they have already
authenticated.
Bring your own device (BYOD):
VanArsdel wants to continue to support users and their mobile and personal devices, but the company is
concerned about how to protect corporate assets that are stored on these devices. The company does not have
a strategy to ensure that its data is removed from the devices when employees leave the company.
Customer Support
VanArsdel wants a mobile app for customer profile registration and feedback. The company would like to keep
track of all its previous, current, and future customers worldwide. A profile system using third-party
authentication is required as well as feedback and support sections for the mobile app.
Migration:
VanArsdel plans to migrate several virtual machine (VM) workloads into Azure. They also plan to extend their
on-premises Active Directory into Azure for mobile app authentication.
Business Requirements
Hybrid Solution:
A single account and credentials for both on-premises and cloud applications
Certain applications that are hosted both in Azure and on-site must be accessible to both VanArsdel
employees and partners
The service level agreement (SLA) for the solution requires an uptime of 99.9%
The partners all use Hotmail.com email addresses
Mobile App:
VanArsdel requires a mobile app for project managers on construction job sites. The mobile app has the
following requirements:
The app must display partner information.
The app must alert project managers when changes to the partner information occur.
The app must display project information including an image gallery to view pictures of construction projects.
Project managers must be able to access the information remotely and securely.Security:
VanArsdel must control access to its resources to ensure sensitive services and information are accessible
only by authorized users and/or managed devices.
Employees must be able to securely share data, based on corporate policies, with other VanArsdel
employees and with partners who are located on construction job sites.
VanArsdel management does NOT want to create and manage user accounts for partners.
Technical Requirements
Architecture:
VanArsdel requires a non-centralized stateless architecture fonts data and services where application, data,
and computing power are at the logical extremes of the network.
VanArsdel requires separation of CPU storage and SQL services
Data Storage:
VanArsdel needs a solution to reduce the number of operations on the contractor information table. Currently,
data transfer rates are excessive, and queue length for read/write operations affects performance.
A mobile service that is used to access contractor information must have automatically scalable, structured
storage
Images must be stored in an automatically scalable, unstructured form.
Mobile Apps:
VanArsdel mobile app must authenticate employees to the company’s Active Directory.
Event-triggered alerts must be pushed to mobile apps by using a custom Node.js script.
The customer support app should use an identity provider that is configured by using the Access Control
Service for current profile registration and authentication.
The customer support team will adopt future identity providers that are configured through Access Control
Service.
Security:
Active Directory Federated Server (AD FS) will be used to extend AD into Azure.
Helpdesk administrators must have access to only the groups of Azure resources they are responsible for.
Azure administration will be performed by a separate group.
IT administrative overhead must be minimized.
Permissions must be assigned by using Role Based Access Control (RBAC).
Line of business applications must be accessed securely.

You need to assign permissions for the Virtual Machine workloads that you migrate to Azure.
The solution must use the principal of least privileges.
