XenApp 7.6 first look – part one: upgrading from 7.5

Citrix released the new version of XenApp and XenDesktop 7.6 on September 30th. It’s very much a point release, introducing some features that got removed from the architecture change from IMA in 6.5 to FMA in 7/7.5.

The full list of what’s new can be found on eDocs.

My top three feature picks

First look: XenApp and XenDesktop 7.5 – part seven (HA & load balancing changes)

This is part seven of a series looking at XenApp 7.5 & 7.6.

Part one – What’s new, and installation
Part two – Configuring the first site
Part three – Preparing my XenApp template image
Part Four – Creating the machine catalog to give me a hosting platform
Part five – Creating the delivery group to publish apps and desktops to user
Part six – new policy filtering options available

For those familiar with the way Load Balancing works in XenApp 6.5, the changes in 7.5 are quite radical.

Gone are the load balancing policies one is used to. Also gone are the worker groups that we used to silo servers, for both application and server grouping, and to perform server fail-over between sites. Gone is the ability to have single global farms, and use zones to segregate our servers into data-centre sized groups with the ability to fail over one region to another.

Some of the topics raised in this post form part of a talk I’m giving at GeekSpeak Tonight at Synergy LA. If you’re a follower of the blog or follow me on twitter do stop and say hi!

Everything has changed. And not all in a good way. Let’s dig deeper

Part three – Preparing my XenApp template image
Part Four – Creating the machine catalog to give me a hosting platform
Part five – Creating the delivery group to publish apps and desktops to user
This part – new policy filtering options available
In Part seven I examine some of the load balancing and fail-over changes

If you are familiar with XenApp 6.x policy framework, you’ll probably be applying (or filtering as Citrix calls it) computer policies to either individual servers, worker groups, or Active Directory OUs. XenApp 7.5 has done away with the concept of worker groups, but there are several new ways of applying/filtering XenApp policies that provide even more granularity over worker groups.

I’m helping Build Croydon at London Technology Week

I’m pleased to support the Lives not Knives charity in their Build Croydon event on June 16th, part of London Technology Week.

I’ll be repeating a talk I gave recently to Old Palace Whiftgift school careers fair on working in the IT field, about the kind of work I do as a Cloud Infrastructure Architect, my journey through education and university, and some of the pro and cons of working as an IT consultant.

Exact timings have yet to be announced, but you can register for the event here.
