Case Study: 4
Litware Inc
Overview
Litware, Inc. is a pharmaceutical company.
Litware has an office in Montreal. Litware has a marketing department and a research department.
Existing Environment
Network Infrastructure
The network contains a single Active Directory domain named litwareinc.com. The domain contains
1,000 physical servers that run Windows Server 2008 R2.
All of the servers are located in a leased data center that has a high-bandwidth, low-latency network.
The data center contains third-party iSCSI SAN storage devices that support an SMI-S provider.
Application Infrastructure
Users in the research department use multiple instances of a three-tier application named Appl.
App1 consists of the components shown in the following table.
The Web Server (IIS) server role, WMI providers, Windows services, Windows drivers, and web
applications will be installed on the servers that host Tier 2.
Problem Statements
Litware identifies the following issues:
• The cost of leasing data center space is increasing steadily.
• The research department users report that it takes too long to provision new instances of
Appl.
Requirements
Planned Changes
Litware plans to deploy 400 additional servers that will run Windows Server 2008 R2. The servers will
be configured as shown in the following table.
Litware also plans to deploy the following System Center 2012 components:
• Orchestrator
• App Controller
• Service Manager
• Operations Manager
• Data Protection Manager (DPM)
• Virtualization Machine Manager (VMM)
Litware plans to provide the research department users with the ability to deploy instances of Appl.
Private Cloud Infrastructure Requirements
Litware identifies the following requirements for the planned private cloud infrastructure:
• VMM must be available if a server or a service fails.
• Virtual machines must be provisioning by using SAN copy cloning.
• The implementation of App Controller must support single sign-on.
• The implementation of Service Manager must support French and English.
• The implementation of VMM must support the provisioning of virtual machines by using SAN
copy.
• Virtual machines hosted on Hyper-V failover clusters must remain available during the
installation of Windows updates.
• Physical servers that have workloads that are suitable for a virtualized environment must be
virtualized. Performance data must be taken into account when identifying which servers must be
virtualized.
Private Cloud Integration Requirements
Litware identifies the following requirements for integrating the System Center 2012 components:
• Incidents in Service Manager must be resolved automatically, whenever possible.
• Alerts generated by Operations Manager must trigger incidents in Service Manager.
• Operations Manager alerts triggered by VMM events must be remediated automatically,
whenever possible.
• All of the Orchestrator components responsible for executing the activities of Service
Manager workflows must be highly available.
Private Cloud Services Requirements
Litware identifies the following requirements for managing services in the private cloud:
• App1 must be deployed by using a VMM service template.
• The Tier 2 of App1 must be deployed as a highly available virtual machine.
• The research department users must use App Controller to deploy virtual machines and
services.
• The virtual machines deployed by the research department users must be hosted on servers
in the research department.
• The virtual machines in Tier 1 of App1 must be configured as cluster nodes by using the
Network Load Balancing (NLB) feature.
• A web application named WA1 in Tier 2 of App1 must use a connection string that points to
a Microsoft SQL Server database in Tier 3 of Appl.
• The software components included in Tier 2 of App1 must be deployed as Microsoft Server
Application Visualization (Server App-V) packages, whenever possible.
###EndCaseStudy###
You need to identify which component or components of Tier 2 of App1 can be deployed by using
Server App-V. Which component or components should you identify? (Each correct answer presents
part of the solution. Choose all that apply.)
A.
The Web Server (IIS) server role
B.
Web applications
C.
Windows services
D.
WMI providers
E.
Drivers
Explanation:
* From scenario:
The Web Server (IIS) server role, WMI providers, Windows services, Windows drivers, and web
applications will be installed on the servers that host Tier 2.
* Not all applications are supported for use with Server App-V. Applications such as antivirus
software that require device or kernel driver support are not supported. ServerApp-V is primarily designed for use with business applications or the business tiers of multi- tiered
applications. Consequently some large server applications such as Microsoft Exchange Server,
Microsoft SQL Server, and Microsoft SharePoint are not supported.
* While there is no list of supported applications for use with Server App-V, Server App-V has been
optimized to create virtual application packages for applications with the following attributes:
/ State persisted to local disk
/ (C) Microsoft Windows Services
/ (A) Internet Information Services (IIS)
/Registry
/ COM+ / DCOM
/Text-based Configuration Files
/WMI Providers
/Microsoft SQL Server Reporting Services
/Local Users and Groups
/Scheduled Tasks
/Microsoft SQL Server Databases
