Lenzker’s #VMware #Horizon Guide (Lab Implementation): Access Layer – Load Balanced Connection Server

In the following article I am going to tell you how easy it is to set up a load balanced Horizon View environment. But remember: Just because something is easy to install it is not necessarily easy to design. There are multiple design affecting factors I am going to discuss in my #design guide. There are many Installation Guidelines out there, so I will keep it quick and simple and try to give you some hints what to do or not to do.

What do I want to achieve or show to you in this blog post?

  • Creation Redundant Connection Server to access virtual Desktops
  • A redundant Load Balancer in front of it (#NSX ftw)
  • Internal Access only – I spent a lot of time with the Unified Access Gateway and show you in the second blog post about how to enable access over the Internet into your Horizon Homelab

Connection Server

The Connection Server is a core component within our Horizon View environment. It gives us the opportunity to create Desktop Pools out of Windows / Linux machines or Application Pools (based on Microsoft RDSH-Hosts) and entitle them to any Active Directory User in our environment. It offers us the following key functionality

  • Brokering between Endpoints (that have the Horizon Client installed) and a virtual Desktop / Remote Desktop Session Host (Application)
  • Authentication Handler (AD only or 2nd factor)
  • View Administration via web-based (Flash :-/ ) user interface
  • HTML5-Client to access the Desktops/Applications without the need of a client
  • Connection to the vCenter Server to create new VMs / Desktops

Lenzker’s #VMware #Horizon Guide (Design): Management & Virtualization Layer

This section within my VDI series is not just relevant for VDI environments. In the following I will cover many things that are relevant for regular vSphere (cloud-a-like) environments.

The Management & Virtualization Layer plays quite an important role within a VDI environment. Within EUC solutions we typically should focus on the User and the User experience. But before we can deliver a performant, reliable and available working environment we need to make sure the layer on the bottom is rock solid as well.

What is the purpose of this layer?

  • Hosting Instances of Virtual Desktops
  • Hosting Instances of Remote Desktop Session Hosts (RDSH)
  • Hosting Management components
    • Components for brokering between Endpoints (Desktop User) and the Virtual Desktops  Horizon View)
    • Components for Integrating with Virtualization Management (Horizon View & vCenter Server)
    • Delivering Applications into the Virtual Desktops (App Volumes)
    • Monitoring of the Environment (e.g. Icinga)
    • Operations Management (vRealize Operations Manager and Log Insight)
    • Management of the Virtual Machines (aka Desktops / RDSH Hosts) and the Hypervisor (vCenter Server)
    • Component for managing Security relevant components (NSX-Manager)

In my design guide I will write about general design decisions regarding the management & virtualization layer. In my implementation guide I will give you hints about the setup of the environment.

The goal of this post is to describe / discuss design implications, design decisions and characteristics for the following relevant Products within the core Layer in their most current release:

  • vSphere Layer
  • vCenter Server
  • NSX Manager
  • Horizon View Connection Server

Implementation Details can be found in the corresponding Implementation post I have created.

Lenzker’s #VMware #Horizon Guide (Lab Implementation): Management & Virtualization Layer

Before we can start with the implementation guide I want to give a brief description what key functionalities must exist.

The following components has been installed and configured:

  • vSphere ESXi host (physical or nested)*
  • vCenter Server (Appliance)*
  • HA/DRS Cluster
  • vSAN Cluster
  • Active Directory Domain Controller (including DNS)*
  • Microsoft Certificate Authority Role*
  • NSX Manager*
  • FTP Service (for backing up NSX Manager)
  • CIFS-Share for UEM User Profile Archive and Config files

*Required.

This will be the first post in my Horizon Guide implementation section. Since my focus is on Horizon I will not go through each of the steps that are involved in setting up the foundation. If you want to get a feeling of the purpose of my blog series: Check it out here.

In my design guide I will write a little bit about general design decisions regarding the management & virtualization topic. In my implementation guide I will quickly go through the setup I have chosen.  As a side note I want to remember you to always use English Language and Keyboard Layout :-). Going into native US-Mode for all kind of setup will keep a lot of pain away from you.

Lenzker’s #VMware #Horizon Guide: Overview

Before being selected as an EUC champion I was already planning a bigger guide on how to design and implement a feature rich and enterprise ready VMware Horizon environment (Check out my opinion about the evolvement of VDI solutions over the years).

In 2017 VMware is putting more and more effort into transforming the enterprises into digital workspaces with their Workspace One solution / initiative. Within Workspace One VMware combines Horizon with Airwatch technology (for device management and application delivery).

Since my homelab has been a little bit underutilized over the last months I decided to built up an Horizon environment , including most of the Software pieces of Horizon Enterprise. Lucky me: VMware has just announced Horizon 7.2 which finally includes a new help desk tool to deliver faster 1/2nd level support to our (beloved) users.

My goal of this series is not just to have a simple implementation guide. I want to give a guideline about important things from an architectural point of view as well.

Horizon View: Java.lang.IllegalArgumentException: Invalid paramaters during Cluster selection

I observed this in my homelab while multiple nested ESXi were not available. If you create a Desktop Pool in Horizon 7 (and I guess earlier as well) the following meaningful error might show up during the select of a host or cluster resource:

java.lang.IllegalArgumentException: Invalid paramaters during Cluster selection

Going through the Connection Server log files I figured out the java exception is called when the vCenter is crawled for all available Hosts and Clusters.

The routine is crashing when it hits an disconnected or not-responding ESXi host within the inventory.

Make sure every ESXi host is in a connected state.

ESXi hosts within some maintenance can really steal the show right here.

Make sure to get rid of this ESXi host by fixing the host or removing the host from the inventory. Please be aware of that a remove will also affect the your distributed switch.

VMware User Environment Manager #UEM: Predefined settings – Dynamic Placeholder

I created several blog posts about the Predefined settings so far that hopefully gave you some understanding about the basic and advanced concepts.

In the following I want to show you a little bit about a feature not all of us know:

The opportunity to create dynamic predefined settings with the help of Environment variables and placeholders.

Placeholders within UEM’s predefined settings.

Within the predefined settings you are able to define variables that will be dynamically set during the runtime.

How can we do that you ask? Just use the the following placeholder within your default/predefined settings (Case sensitive):

[Flex#%environment variables%]

The following example should show you how we can use this functionality to deliver a flexibel dynamic and context-based environment for the user (that almost sounds like marketing once again).

VMware User Environment Manager #UEM: Predefined settings – Deep how-to (Internet Explorer)

In on of my last posts I have explained what the basic concept of VMware’s User Environment Manager (UEM) is and how we can use it to pre-configure or enforce specific settings of applications in our Desktop environment.

In the following I am going to dig a little bit deeper and show you how those concepts get configured and can be used in the world of UEM.

Create Default Settings with the Application Profiler

Once we have installed the Application Profiler we are able to create config files for UEM that explain which portion of the filesystem/registry is a part of the application’s user data.

The process is quiet simple. Start the Application Profiler, start the application from within and configure the relevant settings you want to enforce or have as a default configuration.

VMware User Environment Manager #UEM: Predefined settings (Basic concepts)

The power within User Environment Manager (UEM) aligns with its ability of being able to create a managed personalized environment for the end-user (even/especially in a floating environment where no one has a dedicated virtual desktop).

One great feature to increase the productivity of the user is been implemented by having multiple and different pre-defined settings applied to a Window setting or application based on certain conditions.

### Check my further readings ########################

In the following I am going to document how what does different pre-defined settings mean.

I am assuming you already have the UEM infrastructure installed and configured. If that’s not the case, check out this post.

What are pre-defined settings

I remembering getting on-boarded at a financial provider somewhen in the 90’s (oh boy..I am getting old). Receiving AD-Accounts, Lotus Notes-Account, several other access data and a big document how to setup those applications. 5 hours later I was quiet ready to start doing my tasks.

Let’s troubleshoot User Environment Manager (#UEM) 9.X: How to avoid errors during the installation

As I have written in my last post UEM is a game changer in the way how we can create great VDI solutions.

Having worked a lot with VMware’s User Environment Manager (UEM) within the last month I saw many errors made and occurring during the installation phase.

Even though the the installation is quiet straight forward, some minor mistakes can happen from time to time. I am going to summarize which symptoms might occur, how to check to gather further information and what most possiblely has caused the malfunction.

At the moment the post is focusing on the Active Directory Group Policy based installation & configuration within UEM. The newest version 9.1 allows us to it also in a non-ad way. If demand is there, I can add a section for that topic as well.

I am not going to cover the basic installation steps. Chris Halstead did a great job on that topic (and for all the things he worked on [flings, blogs, etc.]).

Please use that one for the basic installation tasks and come back to this post if you need to troubleshoot further ;-) With the following list you can fix 98% of the problems that might occur during the UEM installation ;-).
