Planning of desktop virtualization 1 integration of applications (I)

 

Abstract: Since the second half of last year, the desktop virtualization market has become increasingly popular with many customers.

After consulting about the desktop virtualization solution, many people talk about it as "desktop cloud", but applications

Integration determines the success or failure of the desktop virtualization project.

As a result, user applications cannot be used, or the user experience is poor. A good consultant must understand

How to integrate applications.

Overview:

As a good consultant, we must understand the architecture of desktop virtualization and the differences between it and traditional desktop, such:

 

 

For example, a complete desktop contains the following three aspects:

Operating System

Applications

User (including user data and user configuration files)

Desktop virtualization separates these three parts, and all the data is concentrated in the data center, while the traditional desktop three are concentrated together, so the security is not high.

I. Types of applications in desktop virtualization

Applications are classified by technology as follows:

Installation: applications are part of desktop images.

Stream: applications are delivered to virtual desktops over the network without affecting the local registry.

Server hosting: applications are installed on XenApp servers and delivered through the HDX protocol.

 

Ii. Differences between applications

 

Type

Differences

Installed

Streamed

Hosted

Concept

Part of the system

Run on the local machine, but do not need to install

Run the command on the XenApp Server

User Access Mode

The user enters the desktop and uses the application

Only Authenticated Users can accept applications

Only Authenticated Users can accept applications

Update

Update the application in the System Image

Update Application Profile

Update the application on the XenApp server.

Performance

Directly affects the CPU and memory of the virtual desktop

Directly affects the CPU and memory of the virtual desktop

Only Citrix Explorer will apply the CPU and memory of the virtual desktop, and the application itself will not apply

Resource usage

Bind to desktop

Bind to desktop

Bind to XenApp Server

 

The table above shows the differences,

Streamed has the least impact on virtual desktop resources.

Streamed and Installed methods must pass authentication before they can be accessed.

The three update methods are different.
