Web Application Goals
• Lower Total Cost of Ownership
• Centralization of Application Logic and User Interface
• Simple browser based application access
• Simple Cross Platform User Interface (HTML, XML, etc.)
• Faster application development and deployment
• Reduced desktop/workstation maintenance costs
User Interface Application Logic Business Data
Citrix Confidential
Compromises with Web Applications
• Simplistic Thin User Interface vs. Robust Interface
• Web application does not necessarily equal thin application
– Bandwidth requirements – data transfer to client
• Consistency across client devices
– Different browsers have differing functionality
• Web browser requirements
– Platform availability
– Platform functionality
• Web browser component management
– ActiveX, JVM, Java Components & Plugins
Citrix Confidential
Trends with Web Applications
• Attempts to improve user interface – more robust
– Active X, Java, Client Side Scripting
– Improvements move new components to the desktop
– Additional client side resources are needed
• New components must be managed on the client
– Browser plugins and components
• Application security concerns
– Browser & plugin security
– Management of browser updates and security patches
• The web browser is an application – must be managed

Business Data
• Centralize management of browser and components
• Standardize on the required web browser
• Ensure browser is secure and up to date
• Deliver consistent application performance
– Across the enterprise, regardless of connection type

3 Key Factors
• Average Bandwidth Consumed
– ICA is approx. 51% less than raw HTTP
• Network Traffic Bursts
– Highest ICA peak: 29.33Kbps
– Highest HTTP peak: 56.57Kbps
• Serviced Users

SpeedScreen Browser Acceleration
• Introduces major performance improvements for
users connecting to applications that:
– Embed JPEG and GIF images within MSHTML pages
• Supported Applications are:
– Internet Explorer (IE 5.5 and higher)
– Microsoft Outlook

Performance
SpeedScreen Browser Acceleration
• Less bandwidth and allows users to interact with the browser:
– Graphically rich pages are downloaded – Large images are downloaded
• The users browser experienced is improved by:
– Background Image Delivery – Progressive Drawing
– Responsive Scrolling
