About two and a half years ago I published the ultimate Citrix XenDesktop 7.x internals cheat sheet, version 1.0 and it turned out to be a big hit. In the meantime, it has been viewed over 80.000 times already. All the more reason to start working on version 2.0. Since I have been writing about Citrix technologies for the last couple of years I have built up a broad archive, which I can now partly (re) use and re-write to come up with an even more detailed edition, version 2.0 of the Citrix XenDesktop 7.x internals cheat sheet. I would strongly advice you to download a .PDF copy – If you like the blogpost, you’ll love the .PDF, trust me! It includes a full Table of Contents making it easier to navigate.
Inside Citrix: Web Interface & StoreFront — XML-based user authentication
Initially, with the introduction of StoreFront it relied solely on its authentication service for user authentication purposes. This, as you might be aware is different from Web Interface, which will directly contact one of the configured Delivery Controllers where the Broker/XML service will take over. Since Web Interface is still widely deployed and used in (large) production environments (and StoreFront now also supports XML based user authentication) I would like to talk, in a bit more detail about both authentication methods available today.
Demystifying the Citrix XenApp logon, enumeration and launch steps — new details included
This continues to be a topic of interest. Not only is it interesting and fun (right?) to know what is going on underneath the hood once you fill in your user credentials, it can also be very helpful when it comes to troubleshooting certain issues. While I have written about the login, enumeration and launch processes before, again I managed to include a couple of subtle changes/details.
How to: Upgrading and configuring StoreFront 3.0 – The Unified Experience!
During the last couple of weeks I have been testing several StoreFront / Receiver features. Relatively simple things like single sign-on for Receiver, working with multiple stores, hiding applications and/or desktops from StoreFront (Store) using PowerShell etc. things like that. At first I started out with the Tech Previews of the X1 Receiver and StoreFront 3.0, which worked ok, but I couldn’t do everything I wanted. When I reverted back to the (back then) latest Receiver build things were again fine and I could continue testing.
Citrix IMA vs. FMA… XenDesktop components and terminology cheat sheet
This post is meant to provide you with a quick comparison, a cheat sheet if you will, between the two architectures. As you all (should) know by now, with the introduction of XenDesktop 7.x XenApp became part of the Flexcast Management Architecture, or FMA in short, and with this came certain terminology and conceptual changes. Here I would like to show you how each former 6.5 (IMA) XenApp component has its equivalent in the FMA world. Although technically there are some differences, on the functional side of things there is not much between them. To be clear, I’m not focusing on features that are in IMA and (still) not in FMA.
Citrix Synergy 2015, here’s what to expect. Or not.
Next week I will be in Orlando attending my first ever Citrix Synergy and as you can imagine there’s a lot to be excited about and look forward to. To name a few… there will be dozens of technical deep dive and Geek Speak sessions, meeting up with community friends, getting to know new people, the Keynote, new and (hopefully) surprising product announcements, dinner parties, other parties :) the welcome reception, TechEdge, the closing appreciation party in the Universal Studio’s etc. And besides all that I also have my very own Match.Geek sessions to look forward to (exiting stuff). Yes, I think it’s safe to say that we will all have a great time in Orlando, once again. Like many others, I have my expectations and hopes on what will be announced at Synergy this year, so without further ado I’ll list them here.
The glass is half full… 50+ reasons why I think it might be time to move to XenApp 7.6!
In this post I’ll list a whole bunch of reasons why I think it might be time to move your current XenApp IMA setup onto the new and enhanced FMA, which, depending on your license, could be either XenApp and/or XenDesktop. I’m sure you’ll find some of my arguments a bit to far-fetched or perhaps plain stupid even, and that’s fine. Feel free to comment. As the title implies I’m trying to take a positive approach here, so I won’t focus on any of the features (still) left out. Eventually we will all migrate, it’s only a question of when. Note that the below comments are in a random order.
Citrix XenApp & Microsoft (online) Lync… Things to be aware of. My findings!
Just recently I was in the process of researching to use Lync online (Office 365) in a XenApp HSD environment for one of our customers. To be honest I expected this to be a relatively straightforward process, install the software, configure, perhaps adjust my sizing numbers somewhat, test and take it from there. But what I found was that using Lync online combined with XenApp has its limitations. Of course some of these limitations can be dealt with, others however, we just have to except or take another route completely.
The ultimate Citrix XenDesktop 7.x internals cheat sheet!
Ever wondered what happens after a user fills in his or her username and password? What the difference is between internal and external user authentication, resource enumeration and the accompanying launch process? Or what about Web-Interface and StoreFront, do they both have the same authentication mechanism? What are the differences between the server and desktop VDA’s? What about the VDA and XenDesktop internals, what happens inside a VDA when a resource is launched? How does a connection get brokered? Read about this and more during the next 8 (mini) chapters.
