Each office contains at least one domain controller from the corp.fabrikam.com domain. The main office contains all the domain controllers for the rd.fabrikam.com forest.

All the offices have a high-speed connection to the Internet.

An existing application named WebApp1 is hosted in the data center of the London office. WebApp1 is used by customers to place and track orders. WebApp1 has a web tier that uses Microsoft Internet Information Services (IIS) and a database tier that runs Microsoft SQL Server 2016. The web tier and the database tier are deployed to virtual machines that run on Hyper-V.

The IT department currently uses a separate Hyper-V environment to test updates to WebApp1.

Fabrikam purchases all Microsoft licenses through a Microsoft Enterprise Agreement that includes Software Assurance.

10. Topic 2, Contoso, Ltd Case Study B

Overview

Contoso,Ltd is a US-base finance service company that has a main office New York and an office in San Francisco.

Payment Processing Query System

Contoso hosts a business critical payment processing system in its New York data center. The system has three tiers a front-end web app a middle -tier API and a back end data store implemented as a Microsoft SQL Server 2014 database All servers run Windows Server 2012 R2.

The front -end and middle net components are hosted by using Microsoft Internet Inform-non Services (IK) The application rode is written in C# and middle- tier API uses the Entity framework to communicate the SQL Server database. Maintenance of the database e performed by using SQL Server Ago-

The database is currently J IB and is not expected to grow beyond 3 TB.

The payment processing system has the following compliance related requirement

• Encrypt data in transit and at test. Only the front-end and middle-tier components must be able to access the encryption keys that protect the date store.

• Keep backups of the two separate physical locations that are at last 200 miles apart and can be restored for op to seven years.

• Support blocking inbound and outbound traffic based on the source IP address, the description IP address, and the port number

• Collect Windows security logs from all the middle-tier servers and retain the log for a period of seven years,

• Inspect inbound and outbound traffic from the from-end tier by using highly available network appliances.

• Only allow all access to all the tiers from the internal network of Contoso.

Tape backups ate configured by using an on-premises deployment or Microsoft System Center Data protection Manager (DPMX and then shaped ofsite for long term storage

Historical Transaction Query System

Contoso recently migrate a business-Critical workload to Azure. The workload contains a NET web server for querying the historical transaction data residing in azure Table Storage. The NET service is accessible from a client app that was developed in-house and on the client computer in the New Your office. The data in the storage is 50 GB and is not except to increase.

Information Security Requirement

The IT security team wants to ensure that identity management n performed by using Active Directory.

Password hashes must be stored on premises only.

Infrastructure services must remain available if a region or a data center fails. Failover must occur without any administrative intervention

• Whenever possible. Azure managed serves must be used to management overhead

• Whenever possible, costs must be minimized.

Contoso identifies the following requirements for the payment processing system:

• If a data center fails, ensure that the payment processing system remains available without any administrative intervention. The middle-tier and the web front end must continue to operate without any additional configurations-

• If that the number of compute nodes of the from -end and the middle tiers of the payment processing system can increase or decrease automatically based on CPU utilization.

• Ensure that each tier of the payment processing system is subject to a Service level Agreement (SLA) of 9959 percent availability

• Minimize the effort required to modify the middle tier API and the back-end tier of the payment processing system.

• Generate alerts when unauthorized login attempts occur on the middle-tier virtual machines.

• Insure that the payment processing system preserves its current compliance status.

• Host the middle tier of the payment processing system on a virtual machine.

Contoso identifies the following requirements for the historical transaction query system:

• Minimize the use of on-premises infrastructure service.

• Minimize the effort required to modify the .NET web service querying Azure Cosmos DB.
