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.
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.
Sh*t just got real… The Nutanix Platform Expert Program!
Last week Nutanix launched their flagship certification program, the Nutanix Platform Expert. Let me start by pointing out that the NPX program is not ‘just’ another IT certification and that it’s not to be taken lightly by any means. It is set out to become, and I quote, the most rigorous technical qualification in enterprise computing. NPX candidates are expected to have a considerable amount of IT industry (hands-on) experience and to be expert technologists, consultants, and solution architects with portfolios of work reflecting this expertise, with a strong focus on hyper-converged architectures. And no, I’m not trying to scare you. Curious? Learn more about the Nutanix Platform Expert (NPX) program they’ll gladly provide you with everything you want or need to know.
Introducing the -1000 blog series!
Just a short intro to let you all know how I like to approach things, nothing special. Most of my articles tend to be quite extensive. I haven’t done the math, but if I would have to guess I think that most of the articles that I have written consist out of 2500 words an upwards, with a few exceptions here and there. Of course this doesn’t bother me, since I like to write and dig in a bit deeper every now and again. I also haven’t heard any complaints from you guys, so I guess I’m good.
