Agenda
Infrastructure
New Components and Features
Core XenApp 5 Upgrade/Migration
XenApp 5 Components
Scenarios

Plan and Design
• Failure to plan is
planning to fail
• Must review business
and technical
requirements as part of
planning process
• Create documented
design and review with
stakeholders

Understand Infrastructure and Limitations
• What do or will these functional
areas look like?
• Hardware, including virtualization
• Network
• Security
• Operating System and Directory Service
• Storage and data

Hardware
Area Example Impact / Consideration
Hardware
refresh plans
Some new physical
hardware to be purchased
for production
Need to revisit old automated server
build
Vendor make
and model
New vendor and model Learn about new vendor’s hardware
maintenance tool
x86 vs. x64 x64 can be used for new
servers only
Ensure that applications function
properly on x64
Virtualization CIO directive to virtualize
for disaster recovery only
Determine process and adherence
to disaster recovery plan
Scalability New servers only will have
additional resources
Adjust Load Evaluator based on
number of users and resource
requirements for each server type

Network
Bandwidth
requirement
New app to be added
that is highly graphical
Need to understand subsequent
bandwidth requirements
Current
bottlenecks
Several international
offices running near
100% utilization
Consider WAN optimization or
WAN upgrade
Planned
upgrades
Two locations tripling in
size and WAN link to
be doubled
Consider whether this will provide
sufficient bandwidth
WAN optimization WANScaler to be
implemented
More bandwidth will be available
Remote user
characteristics
No consistency in
home-based user
network link
Network-related troubleshooting
becomes more complex

Security
Current
security gaps
Secure Gateway only
allows secured external
access for ICA/CGP traffic
Does not allow remote users to
access other data types
New industry
or government
regulations
Use of shadowing requires
user to authorize
If XenApp servers were installed
without requiring user
authorization, need to re-install
Security
Manager
directives
No web servers in the DMZ Need to place Web Interface on
the internal network and
determine secure access
mechanism
Certificate
strategy
Internal certificates to be
used where feasible
To secure Citrix XML traffic, use
internally-generated certificates
for SSL Relay

Operating System and Directory Services
Upgrade vs.
migration
strategy
Existing servers will not be
upgraded; new OS
installation upon refresh
only
If XenApp farm servers will be
refreshed in batches, ensure that
mixed farm considerations are
minimized
Windows
Server 2008
adoption,
including AD
Windows Server 2008 to be
deployed for all new
servers; Active Directory
upgrade at least a year
away
Windows Server 2008 Terminal
Server Client Access Licenses will
be required
Terminal
Services
policies and
profiles
No Terminal Services
profile configured
Instead of defaulting to a local
profile, a Terminal Services profile
should be designated to improve
the user experience

Storage and Data
Citrix
databases
Data Store, EdgeSight,
Configuration Logging,
SmartAuditor
Oracle and SQL Server supported for
most requirements; only SQL Server
2005 supported for all
Backend
data
sources
New ERP application to
be brought online with
database servers and
support at vendor
location
Should rethink where database servers
are located because XenApp servers
and data sources should be at same
physical location to optimize application
responsiveness
Upgrade or
new
SAN/NAS
New SAN to be
implemented
User data, Terminal Services profiles,
and other data to be moved to SAN
DR/failover
data
repositories
No testing process for
data store database
backup
In the event of a data store failure,
server farm cannot be restored

Don’t Forget About . . .

New Features
Feature Description Sample use case
Application
Streaming
Application Streaming now
includes inter-isolation
communication, HTTP/S
streaming, and differential updates
for offline applications.
A remote user needs to have three application
profiles, each containing Microsoft Office,
streamed securely to a remote location. With
inter-isolation communication, Microsoft Office only
needs to be streamed once, and the profile can be
streamed from an SSL-enabled web server.
Web Interface
User interface
and
Authentication
Usability enhancements including
mobile-sized interface, as well as
Kerberos ticketing and generic
RADIUS support available as
authentication options through
Web Interface 5.0.1.
The security manager of your company has
directed that all authentication to corporate
resources must occur by means of a new third-
party RADIUS product.
IPv6
Communica-
tions
By means of Secure Gateway 3.1,
secure external communications
can be configured to occur by
means of IPv6.
Because a government agency must adhere to a
mandate to communicate by means of IPv6
addressing, the agency implements Secure
Gateway 3.1 with IPv6.
ClearType Font
Smoothing
To improve the user display,
ClearType Font ClearType
improves readability on LCD
screens using sub-pixel rendering.
Windows Vista users report that their applications
appear clearer when accessed locally as
compared to XenApp-based applications, so the
administrator enables ClearType Font Smoothing.

New Features for Windows Server 2008 Only
Special Folder
Redirection
Desktop and/or (My) Documents
folder can be redirected without
the use of Active Directory GPOs,
minimizing administrative effort
and eliminating user confusion
when saving files.
Previously, users intermittently saved documents
to the Documents folder on the local drive and the
Documents redirected folder, and many help desk
calls were generated because users perceived that
documents had been lost. By using Special Folder
Redirection, only one Documents folder is
presented to users.
Preferential
Load Balancing
User sessions and/or applications
can receive higher priority and
subsequently be granted more
CPU resources.
A doctor accessing an emergency procedure
database is allocated higher preference as related
to both the load balancing decision and CPU
resources than a hospital administrator processing
insurance claims.
XPS Printing XPS printing can be enabled to
optimize printing and reduce
printer bandwidth requirements.
To address complaints by Windows XP- and Vista-
based users in a remote office that have heavy
printing requirements, an administrator enables
XPS printing.
Installation
Manager
Installation Manager is now based
on Windows Task Scheduler and
Powershell; it supports distribution
of MSI, MSP, MST, and EXE files.
In order to automate the distribution of executable-
based applications to XenApp servers, an
administrator elects to use Installation Manager.

New Features for Platinum Only
Active
Application
Monitoring
Sufficient data can be
gathered and presented
to document SLAs by
means of Application
Performance Monitoring
powered by EdgeSight.
An outsourced IT vendor must document application
availability and performance based on live and synthetic user
sessions during each workday.
Self-Service
Password
Reset Only
Deployment
Single Sign-On powered
by Password Manager
can be configured such
that only self-service
password reset
functionality is enabled
for users.
Company A has no requirement to enable password
management for applications. However, due to a short
password reset requirement, users frequently lock
themselves out of their domain accounts after extended
vacations or leave.
