Provisioning Services vs Machine Creation Services 2013 revision

This article has been update with a 2014 revision. Click here to go to the PVS vs MCS 2014 revision.

Over one and a half year ago I wrote a follow up on an article by Citrix architect Daniel Feller. The original article by Daniel Feller needed an update and now mine is getting pretty outdated as well.

I’m writing this in such a way you won’t be needing to read the earlier articles but of course you are free to do so anyway.

The first article by Daniel Feller can be found here.
My article called Provisioning Services vs Machine Creation Services can be found here.

After Daniel posted his decision tree over two years ago a lot has happened. New Citrix features like XenServer Intellicache and MCS for “XenApp on XenDesktop 7” have been released and are changing the whole decision making process.
On top of that vendors started to work on solving the whole storage IO issue.

Citrix NetScaler Access Gateway VPX user scalability numbers explained

The Citrix NetScaler Access Gateway VPX  and MPX are great platforms for secure remote access to your company network.

When working with Access Gateway there are two methods of setting up your connection.

  1. An integrated connection to Citrix XenApp and XenDesktop, which we call ICA proxy.
  2. A full SSL VPN connection for access to company servers, which we call SSL-VPN. Both Access methods can be used combined or separate on a Access Gateway node. Both have their own use cases and based on the customer needs you will use either one of them.

Citrix NetScaler Access Gateway is available as a virtual platform (VPX) and as a hardware platform (MPX).

A very important question to ask when choosing between a VPX and MPX model is the amount of users you need to facilitate on the Access Gateway solution. The amount of users is divided between the amount of ICA Proxy users and the amount of SSL-VPN users. A single SSL-VPN user load consumes a lot more resources then a single ICA Proxy user and the resource load of a single SSL-VPN session is impossible to predict because it changes all the time.

So what does Citrix have to say about this?

How to maximize your virtual Citrix NetScaler Access Gateway performance

How to maximize your virtual Citrix NetScaler Access Gateway performance.

When you are reading this article you have probably been reading another article which is called NetScaler Access Gateway VPX user scalability numbers explained If you haven’t read this article I advice you to do so before continuing.

In the article mentioned above I focused on explaining why there are so many different “facts” about the amount of users you can facilitate on a virtual Citrix NetScaler Access Gateway. In this follow up article I will try to go into a bit more technical detail about CPU resource consumption and most importantly how you can make sure to get every single possible user sessions out of the virtual appliance.

Citrix NetScaler Access Gateway VPX user scalability numbers explained

During the years Citrix is working on moving customers from the Citrix Secure Gateway to Citrix NetScaler Gateway platform. Last year Citrix announced that they will move to one Gateway platform based on the Citrix NetScaler platform. Up to now they had several code bases for similar functionality.

Let me start by mentioning that I think it’s a great step to get customers of the Secure Gateway platform. Citrix NetScaler Gateway is more secure and offers more functionality. The latest step to move to one base platform for Access Gateway is understandable because it saves a lot of time in development and support for Citrix. It also makes a consultants life easier because we had a hard time explaining the differences.

CPU scheduling and memory optimization solutions compared Part 2 of 2 Memory

If you are reading this you might also be interested in part 1 of the CPU scheduling and memory optimization solutions series.

For a while now customers and colleagues are asking me which tool to use when it comes to CPU scheduling and Memory optimization. We use several management products and end up with more than one product utilizing these tasks. Choice is good but do we just enable them all and if not what’s the best way to configure this?

When you look a little bit deeper then plain and simple marketing you’ll notice that the way the different products handle memory optimization totally different and combining some of them will degrade system performance or might not work.

To start off I will first try to explain how each product works and will then summarize and see if we can work through them and work to a proper advice.
