Deze week hebben we onze eerste Detron bloggers borrel gehouden waar we, onder het genot van een hapje en drankje, uitvoerig met elkaar hebben gesproken over de meest uiteenlopende onderwerpen rondom het schrijven, onderhouden en publiceren van blogs plus overige technische artikelen en aanverwante als whitepapers, infographic ‘s, survey ‘s, presentaties en meer.
The Citrix XenApp & XenDesktop FMA Services complete overview – new 7.12 Services included
The release of XenApp/XenDesktop version 7.12 introduced couple of new FMA services (primarily used by LHC) — time for an update. As you might be aware, I have written multiple articles on the FlexCast Management Architecture in the past (including my book) talking about its core services, their responsibilities, capabilities, communication channels/interfaces and so on. Throughout the past two years I also came up with a nice graphical overview (at least I like to think so) representing a Delivery Controller including all main FMA services. This article/post is meant to provide you with a continues update on the FMA and its primary core services, graphical overview included. Each time something changes you’ll read about it here – as soon as NDA has been lifted of course.
Desired State Configuration & the Citrix XenDesktop DSC Tech Preview
Desired State Configuration (DSC)… Ring any bells? No? It should by now. Although it isn’t a technology or concept thought up by Citrix, it is still very much applicable to Citrix components and infrastructures. DCS is a (still relatively) new management platform for Windows PowerShell allowing you to configure, apply and maintain a certain desired state (duh) on a single or multiple machine(s). A desired state can be anything related to software installation and configuration, the management of files and folders, registry entries, local group and account management, adding and removing server roles and the list goes on. Best thing is, as soon as something changes DSC will step in and correct it for you, preserving the desired state. DSC is a PowerShell extension and ships with Windows Server 2012 R2 and Windows 8.1. Let’s have a closer look at what is needed.
12 services that make up the Citrix XenDesktop Flex Management Architecture!
The Flex Management Architecture is a service-orientated architecture, it consists out of ten, or twelve depending on your point of view, primary services in total. Let me explain, when administering a Virtual Desktop Infrastructure (VDI) for example, the Broker Service, a.k.a. the Desktop service, and the PortICA service both live on your desktop OS based VM’s, which are then part of the FMA as well, making it twelve services in total. Here I’ll provide you with a rundown of all services that make up the FMA including their responsibilities and some background information. I’ve included some artwork as well.
Configuring Citrix XenDesktop 7.x Desktop publishing and Limited Visibility!
With the merge of XenApp into XenDesktop’s Flex Management Architecture (FMA) a lot changed, for most XenApp admins it meant they had to rethink their designs and as a result it was back to the drawing board. Take application, or resource, publishing for example, we now have to deal Delivery Groups and Machine Catalogs, nothing new if you’re used to working with XenDesktop, but if it’s ‘just’ XenApp you know, well… Even now where XenApp 7.5 is a product on it’s own, again, it’s still based on the Flex Management Architecture meaning it also still uses the same wizards and configuration options as in XenDesktop 7.x a few months ago, for the most part anyway.
