Horizon on VMC – Considerations and setting up a lab environment

VMware, , , , , ,

A few months back, I setup a Horizon Environment running in our VMC environment used for lab purposes. Since then, I’ve been asked by several people to go through the setup. So, I’ve also decided to create a blog post on the matter.

This blog post will cover the considerations for running VMware Horizon on VMC, and the technical setup itself of the lab environment I created.

Update 4th May: I recorded a session for the London VMUG on this subject, which you can watch here.

Topics covered;

  • Horizon 7 on VMware Cloud on AWS is not DaaS
  • Horizon 7 on VMware Cloud on AWS Deployment Guide and Supportability
  • Feature Support
  • Horizon on VMC architecture
  • Platform Considerations
    • Identity Management
    • File Shares
    • Image management
  • Network Service
    • VMC Network Segments
    • Load Balancing
    • DHCP
  • Firewall Rules
    • Logging
  • Horizon Connection Broker Configuration
  • Some finl considerations
  • Further Resources
Horizon 7 on VMware Cloud on AWS is not DaaS

I will not cover the details of VMware Cloud on AWS (VMC) in this post, but you can read about it here.

Horizon 7 (or later), running on top of VMC, is not a Desktop-as-a-Service offering. For this, we have our Horizon Cloud offering, which currently supports Azure and IBM Cloud.

Horizon on VMC, acts the same as the on-prem offering, i.e. the same considerations and configurations as you would take, if you deployed Horizon in your own private datacentre.

You can stretch existing Horizon environments to also make use of the compute and storage in VMC, and setup Cloud Pod Architecture between the locations as well. Alternatively, you can run a full Horizon environment solely within VMC itself. By running within VMC, you also ensure your desktops are near in proximity to native AWS services, such as file services, global load balancing services to name some examples.

PowerCLI

PowerCLI with a GUI – Clone a machine, add DHCP Reservations, alter CPUID

VMware, , , , , , , , , ,

In this blog post, I am going to break down a PowerShell code I have created (with help from some colleagues). The functions of this PowerShell code are;

  • Present a GUI form to the end user
    • Connect to a vCenter
    • Select the virtual machine to be cloned
    • Select the datastore the new VM is to be stored on (display DS free space)
    • Select the host for this VM to be created against (display free memory on the host)
    • Set the new VM name
    • Create an IP reservation in both the Production and DR DHCP Scopes

Below are some functional screenshots of the code’s GUI and also a rough flowchart of what I needed to achieve.

You can skip to the end to find the full code or my github.

TAM Lab Recording

Since posting this blog, I also covered this in a VMware TAM Lab recording which you can watch below.

A little more background on the script

So my customer had a dedicated environment for hosting their custom application, however these applications were built and running inside an old unsupported OS which expected to be running on a particular era of CPU’s to run correctly, for example todays Intel Skylake would cause the OS to panic and not run. As you can also imagine with this type of older OS, there are no VM Tools support either.

Here is the architecture diagram;

Providing DR around this environment was interesting, we could protect the VM using SRM and storage array LUN replication. But this also presented some issues, when the VM boots in DR. “what happens with networking?” hence we setup a DHCP reservation on both Production and DR. Meaning we know the VMs IP regardless of where its booted.

How to produce good documentation – Part 3 – Network IP’s & Interfaces

The time is here, lets look at starting to document that network of yours.

Now lets look at the other side of the coin.

SwitchPort Diagrams/Tables

So it’s not all creative visio diagrams, one of the best pieces of documentation I find that I produce is actually a switchport diagram.

Using Excel to diagram out a given number of switches, mapping the interfaces to the hosts or devices in which is connected to them.
