DESKTOP

STREAMING

BY: NEHA SHARMA

INTRODUCTION“It creates a virtualized desktop that can be

managed centrally, yet offers the speed of local execution.”

Best alternative to phone based technical support.

it’s a WEB BASED remote assistance application i.e.,

u can remotely view and control users computer.

Complete ASP support application.

No software to install and Application Independent.

How it works???

Additional applications and operating system components are fetched as needed.Portions of applications reside in local cache

memory.Thus, applications are maintained at central

server but run on end user’s local machine.Environment where application can be made

available on Devices is very managed and controlled way.

Centralized management made upgrades easier and faster.

Soft Grid:-includes ‘Sequencer’, that encapsulates all of the system changes that installation routine makes and places them in a semi- virtualized environment.

Most mature approachSuncor:- gave “Zero Touch Workstation”.

Applications are streamed and Virtualized, users can log on to any machine and receive there own applications.

Suncor uses “METAFRAME” to provide thin Client access to application that point to its back end databases.

Arthur Hitomi:- Chief Technology officer specifies which DLLs or other components can be virtualized , and which need to talk to one another.

VARIOUS VENDORS

STREAMING DESKTOPAim is to centralize applications at the data center to

make them easier to manage and provision.Servers run the application and give users remote

access.Earlier versions used “Blade servers” that simply

moved the processing of a PC to the datacenter and left the input and display at user’s desk.

Now, “DUBBED” desktop streaming retains benefits of central management without throwing away Desktop power.

Thus IT can manage a large number of clients from Datacenter, rather then at each User’s desk.

Reduces the time and hardware cost by letting one server provision multiple desktop clients.

VARIOUS TECHNOLOGIESCitrix, Clear cube and Wyse technology support the

use of VMware and Microsoft Virtual machines on Blades and server, which makes server hosted virtual machines accessible to users through RDP .

Next release of VMware is ESX technology, which will support load balancing across server, easier to maintain.

Ardence, Propero, Stream Theory and Wyse offered streaming software that provisions entire desktop Env. From Server to desktop PC.

Altiris, AppStream and Microsoft pushed concept to next Level By streaming applications rather then Desktop, allowing greater flexibility.

SIMPLIFYING MANAGEMENT

Ardence, Propero, Stream theory and wyse centralize Application & Data.Let users store data locally as well.Altiris, AppStream and Microsoft’s application tools let you set up applications in there

own Virtual Layer or Session.They separate application- specific support files

such as DLLs and libraries from the underlying operating system

By separating into its own virtual layer, products prevent software conflicts.

Manage communication among layers.

ADVANTAGESScreen Sharing- Support rep remotely share

control of a user’s screen, mouse and Keyboard.

Web Based ASP solution- entirely web based, no need to install any software.

Quick implementation- Get up and running with Desktop Streaming is easy.

Flexibility- Many tools like real-time chat, file transfer and screen sharing tools are provided

Application Independent- Desktop streamings’s Versatile technology is browser which is application independent.

Online management and Report Retrieval- Administrators can review entire chat and session logs or access daily reports through secure online administration center.

User Interaction- allow user and the support rep to work together in real time, encourages user participation.

VARIOUS TOOLS

Smart Box- User can leave Question in SmartBox located on Support Providers Website which is routed to all online support rep.

Help Alert- Support rep receives user question and then responds thus establishing a connection between user and support rep on communication server.

Chat Link- a chat sessions begin enabling both parties to exchange messages. User and support rep can address problem which will be solved by support rep.

Viewer- Help Alert opens the viewer to display user’s desktop. Support rep can manipulate any screen element or applications on users computer with mouse and keyboard controls.

File Transfer- also support rep and user can send files to each other, relies on firewall friendly technology that powers screen sharing. These both can take place simultaneously.

ARCHITECTURE

•Designed for maximum performance, reliability and scalability. •Driven by high capacity servers and network equipment.•Clustered servers and backup system for seamless flow.•Robust architecture that protects data and scales easily.

WEB SERVER -

maintained by cluster of high capacity UNIX web server. Switches monitor the network flow. Distributes server request among all servers. Initiate connection between user and support rep.

COMMUNICATION SERVER- facilitates three important Processes.

Screen sharing- enables screen sharing. Session recording- records chat dialogue. firewall access- facilitates firewall- friendly connection.

1. Network Reliability- constantly monitors network through custom

monitoring and altering tools. Performance data is collected regularly.

2. Firewall Configuration- streaming works with leading firewall protocols. May require ports and IP adjustments.

3. Security- Uses latest technology to ensure data

exchanged between users and support rep is completely secure.

Uses password verification technology.

CONCLUSIONCan use web based assistance tools to

efficiently identify and resolve issues.Provide scalable and reliable

environment.Ease of use and flexibilityEasy and low cost methods.
