Citrix on Microsoft Azure

This is huge news! Microsoft Azure has for some time now had a solid IaaS platform with suppor for most of the different Windows Server roles and features, except the most importent one RDS.

Since Microsoft until recently didn’t allow for use of RDS or other options like Citrix to run against Azure, (because of the licensing) people would have to use on-premise solutions until that was allowed / fixed
But now with the latest changes on the Volume Licensing agreement http://www.microsoft.com/licensing/about-licensing/product-licensing.aspx#tab=2 you can now bring SPLA based RDS sal usage in the cloud.

Now this brings two options for a service provider in Azure.

* Session Shared Terminal Servers
* Server VDI Workers (VM/Server Isolation)

So first of, this makes ALL of the different Citrix components supported in Azure not just XenDesktop 7, of course this restricts itself such as RemotePC cannot be used there.

And Citrix has also created two design guides for how you can setup Citric XenApp / XenDesktop in Microsoft Azure. This also requires that users enter to the citrix servers trough a Netscaler gateway on-premise.

And im guessing with the next release of XenDesktop 7 (Project Merlin) will include provisioning options against Azure but until that arrives we will have to manually provision and use PowerShell. Since also Citrix and Microsoft has a strong relationship im guessing that more options on how to host Citrix in Azure will appear.

Monitoring Windows Server 2012 R2

Microsoft just recently released a preview pack of a management pack that can be used to monitor Windows Server 2012 R2, good job Microsoft! Smilefjes

You can download the preview pack here –> http://www.microsoft.com/en-us/download/details.aspx?id=39375

The management pack includes monitors for most of the Windows Server features. Including some awesome feature for Hyper-v 2012 R2, including for instance Host Health Dashboard and Virtual Network Usage.

It also includes for other features such as Cluster, AD, ADCS, RDS, and even Server Essentials.

Now Microsoft should hurry up and release some management packs for System Center 2012 R2 as well that would be great! Smilefjes

A28 Netscaler 10 exam

I recently took the A28 exam from Citrix and wish to share my tips and my experience with this exam.

Now to compare with the 9.2 exam this was A LOT more difficult. Have to say that Citrix has really created a challenging exam which focused a lot on most of the different functions within Netscaler.

There werent so many CLI commands (Which I felt the 9.2 exam was) but more about how to think “when do I use this function over that function”

For my part I have worked with the product some time now and I have taken a traning course on the older version. The best part is the study guide that Citrix offers on their web site.

Which can be found here –> training.citrix.com/mod/ctxcatalog/course.php?id=511

The study guide shows on what areas you will be tested, and on what area you need to know “HOW” which is the most typical case for CLI commands Smilefjes
and “WHEN” is mostly when to use one function or another.

But you should remember most of the cli commands assosiated with each of the focus areas in the study guide.

So my top tips!
* Troubleshooting commands
* SSL (ciphers, converting, importing, binding)
* Load balancing (monitoring, persistency)
* VLANs, IP config and interface configuration
* Link-load balancing
* Use the study guide! and eDocs!

Here are the other points from the study guide how to configure the different parts can be found on eDocs

Error adding a RemoteFX video adapter to a VM running Windows Server 2012 R2

When I was trying to add a remotefx video adapter to a VM running on Windows Server 2012 R2 I got an error message 
Error applying RemoteFX 3D Video Adapter Changes.

And what is that? Well clearly its a GUI bug as I see several other have the same issues as well.The solution was to run this command from PowerShell

Import-Module RemoteDesktopServices

Add-VMRemoteFx3dVideoAdapter -VMName nameofcomputer

SET-VMRemoteFx3dVideoAdapter –VMName nameofcomputer

After that the adapter worked as it should Smilefjes
