Application Server Computing / SBC

There are six major challenges that must be addressed when deciding

how end-users will access their critical business applications:

Application installation and configuration

Prerequisites and requirements of client devices

Bandwidth requirements

Application compatibility Application access from outside the firewall

Security

Application Server Computing Solves all these issues and excels inefficient delivery of applications to the end-user

Citrix IMA Sub Components

Data Store: Central configuration database

LHC:Local Host Cache. Persistent data

cache that exists on each server.

Data Collector: Manages dynamic data and

client enumeration/resolution (replaces ICA

Master Browser).

Zone: Deliberate grouping of PS servers,each with its own Data Collector.



IMA

IMA provides the framework for server to servercommunication & is the backbone of a PS Farm

Delivers core subsystems that collectively providefunctionality to current and future Citrix products

Centralizes all admin tasks into one single GUICMC,Delivery centre

IMA runs on all XenApp servers as a service

Citrix Farm Architecture



ICA is optimized for connections as low as 14.4

kbps. Only mouse clicks, keystrokes, and

screen updates travel the network to generate

exceptional performance.

With over two million ports in

use worldwide, Citrix ICA is a

mature, reliable technology

and is a de facto industry

standard for server-based

computing.

Server based computing usingICA provides an ideal solution

for bandwidth-constrained

environments. It offers users

LAN-like application

performance over virtually any

type of connection.

ICA facilitates the old 16 bit &

the latest 32 bit applications to

run on legacy & multi-platform

clients (with great

performance) that normally

would not be able to run them.

Citrix Features

Performance

Persistent Object Caching improves application

performance and reduces network traffic. Graphics are sent

to the client once and stored locally between application

sessions. This allows application splash screens to be

transmitted once, rather than downloaded to the client each

time

Bandwidth is optimized for network connections as low as14.4 Kbps, and delivers bandwidth-independent

performance over LANs, analog or ISDN modems, WANs,

wireless LANs and even the Internet

Security

Eyes-only data transmission; encrypted by default; SSL

relay

Administrators can lockdown specific files, directories,

and system areas as well as the entire system, improving

the security on LAN/WAN, Intranet or Internet.

Anonymous & registered users can access the Citrix Server

from a Web browser

Application Streaming

Centrally manage all Windows-based desktop applications

Streams applications into an isolated environment onthe desktop

Use them anywhere, anytime even when disconnected Automatically updates and repairs applications

Eliminates application conflicts and regression testing

Ideal for applications that need local CPU resourcesor peripherals

Presentation Server dynamically selects the best deliverymethodvirtualization or streaming

Application Streaming for Desktops add-on licenses available

Instant Application Delivery to desktops



Isolation 2.0

Improves system and application compatibility

Isolates and protects applications from conflicts

Provides ability to configure degree of isolation

Eliminates regression testing

Next-generation isolation technology

Increases performance of isolated applications

Extends compatibility to more Windows applications Provides core technology for Application Streaming

and Application Isolation Environments

Broader application compatibility



Application Hub

Provides central repository for application profiles

Rapidly provision applications to Presentation Serveror directly to end users devices

Uses the same profile to virtualize or stream

Simplifies application inventory management



Application Performance Monitoring

Ensures the best end user experience

Proactively identifies poorly performing applications

Helps IT pinpoint root-cause of bottlenecks

Monitors and records historical application performance Assists in improving capacity planning

Reduces support costs

Collects run-time application crash data

Measures impacts of changes to production environment

Assists in tuning custom-built applications

Powered by Citrix EdgeSight



Single Sign-on

Improves application security

Centralizes and securely stores credentials

Automatically changes passwords

Generates strong passwords for policy enforcement

Reduces help desk calls

Simplifies application access with automated logons Provides self-service password reset

Powered by Citrix Password Manager



Web Interface

Printer Management


25/39


Installed on the client machine before a session is

established with the server.

Client printer drivers are to be installed on the

server so the server can map the printer torepresent the same to the client.

Universal print drivers are to be enabled in casean administrator prefers not to install drivers for

each and every client.

Resource Management

Resource Manager enables you to collect, display, store, andanalyze data about system performance, application or process

use, and user activity.

Use Resource Manager to:

Real-time monitoring.

Analyze and report using records of system activity.

Create billing reports.
