Pubish Applications on Xendesktop/XenApp 6.7

-  in Xeanppp6.5 and previous versions, Applications were installed on Citrix servers then published to end users.
 Xendesktop 7.6,  If I am not wrong Applications are installed on Desktops and delivered to end users as Desktop with Applications installed on it (User still needs a PC to connect to the Delivered Desktop), just like VMware VDIs.

-   I would like to know if Xenapp7.6 does the same functions as Xendesktop 7.6, or it has different functions ?

-   I also want to know on which of the flavors , (whether Xenapp7.6 or Xendesktop 7.6)  can we install Applications and publish them to end users the same way we used to do in Xenapp6.5 and versions before 6.5.

Thank you

Applications can be installed on a desktop OS machine (VM Hosted Apps) or on server OS machines.

Desktop OS machines are restricted to one user or connection per desktop or application

Server OS machines are limited only by server resources to the number of users or connections that can be made to the desktop or applications.

Both types of applications are handled in the Delivery Group node of Studio.

You can change a Delivery From Desktop or Applications or Desktops and Applications. If select a Server OS machine for Desktops only and then later change it to Desktops and Applications, you will need to let the wizard scan the server for installed applications before the applications can be published.

This is all very easy to do.

Well, when you put the DVD , it will prompt you  to choose to install Xendesktop7.6 or Xenapp7.6
If you install Xendesktop7.6 will you still be able to carry out the same functions that Xenapp6.5 and previous versions did ? or Xendesktop7.6 if for delivering Desktop with/without Applications to users, and Xenapp7.6 for delivering Server OS with Applications installed on them...
So what is different between Xendesktop7.6 and Xenapp7.6 ?

***Though if I understand, you can use Machine catalog and select Server OS and install Applications on it , then create Delivery Group and assign users to have access to the applications you installed in the Machine catalog step.
I wonder if server OS( created through Machine catalog) has to be Xenapp/Xendesktop server or any other windows server ?

If you install Xenapp 7.6 will you be able to work with PVS ?
if XenApp7.6 and Xendesktop 7.6 have the same functions , why are they separate products ?
Carl WebsterCitrix Technology Professional - FellowCommented:
Simply for XenApp bigots like me who want to see the name XenApp. :)

Can you work with PVS? It all depends upon your license. For XenApp you need Platinum licenses. For XenDesktop, you need Enterprise licenses.

According to the Matrix on the link above. VDI works only with Xendesktop. Correct ?
Carl WebsterCitrix Technology Professional - FellowCommented:
Depends on your definition of VDI. A server hosted desktop is also a "virtualized desktop infrastructure".

If you want ONLY server OS hosted desktops and apps, you license XenApp. Just like I explained in my article.

If you want both server and desktop OS hosted desktops and applications, you license XenDesktop. That is why a XenDesktop license costs more than a XenApp license.

** What I meant by VDI is that End User has a computer (Thin or Thick) client that connects to a VM provisioned as 1 to 1, or randomly from the loop

** I believe the way I understand Xenapp/Xendesktop 7.6, since I still have a vision of Xenapp6.5, is that:

on 7.6, you create machine catalog and you select server OS, then you create Delivery Group and install applications on the Server you selected , and also select users that will have access to the applications, This is all through the creation of delivery group

The grey area that I was trying to understand is, when creating machine catalog and select Server OS, would this server going to be Xenapp/Xendesktop server ? seeing that you are going to install applications on it and publish them to users, when you go through the creation of Delivery group wizard ?
Or it can be just plain window server without any citrix xenapp/xendesktop installed on it ?

You still do things almost the same way:

Install the OS
Install Updates
Join to Domain
Install VDA (which install the RDS role)
Update VDA to latest public hotfix level (32 at the time I am answering you)
Install and configure applications
Shutdown server
Take snapshot (this is what MCS uses)
Create Machine Catalog pointing to snapshot
Create Delivery Group for Desktop and Applications (if you intent to publish the server's desktop also)
Select apps the wizard finds on the server
Add users allowed access to the desktop and or apps

Excellent CarlWebster !!

I do not want to make this thread too long , it is already pretty long.
in Xenapp 6.5 and previous versions, published Applications are in Installed on CItrix Xenapp server

However I want to understand the steps you described , are you creating regular Windows server (without citrix xenapp on top of the OS) and installing applications on windows server and publishing (delivering) to end users?
jskfanAuthor Commented:
In other words, I still have the Xenapp6.5 vision where Applications are installed on Xenapp and published to end users

when you install the VDA you are making the server a xenapp server.
