Choose your #Citrix #NetScaler … wisely… – via @hlouwers

This is a question I get a lot and I must say that Henny Louwers did answer it well in this blog post!

I spend a lot of my time breaking down the different models of Citrix NetScaler appliances and different Software Editions within the Citrix NetScaler portfolio.

I decided to set up a blog about this since the path is usually pretty much (lengthy but) the same. This does not mean the answer is always easy because there are a lot of questions that need to be answered.

The first thing I would like to get off my chest is the following: Stop seeing/selling the Citrix NetScaler as a replacement for Secure Gateway. It is so much more than that. I often have discussions with various engineers and consultants telling me that Citrix NetScaler is so expensive for a Remote Access solution because Secure Gateway always used to be free. No offense but a Citrix NetScaler solution belongs to the networking department, not the Citrix XenApp sys admin department. Or maybe limited.

That leads me to the first difficult thing of a Citrix NetScaler project. The adoption of the Citrix NetScaler appliances to the networking guys of an organization. They need to embrace the solution to make this a success. For some reason they too see it as a ‘’Citrix’’ solution. For that reason one of the most important meetings to setup is usually with the networking guys to try to explain the L3-L7 functionality of the Citrix NetScaler solution. When they realize it competes with F5, Juniper, Cisco, etc then we are on the right track.

NetScaler Gateway or NetScaler Standard Edition

Usually the first question of a customer is regarding something simple like replacing the Remote Access solution. Since the NetScaler is going to be the main platform for publishing Citrix publications a NetScaler Gateway can be considered as a valid option. This is when I tell a customer it would be wise to spend a little extra on the NetScaler Standard Edition since this would leverage the solution be having full load balancing capabilities (among others). When you compare prices between the NetScaler Gateway and NetScaler Standard Edition you will see that the Standard Edition will be somewhat more expensive but I for one think that it is worth the difference given the feature set that come with the Standard Edition. Of course the NetScaler Gateway can always be upgraded to a NetScaler Standard Edition (or higher) if you will.

Another feature of Citrix NetScaler Standard Edition is the ability to run Citrix Web Interface on the appliance. Honestly, I do think is not really that important anymore….

#Citrix #CloudBridge Connecting to Microsoft #Azure – Technology Preview

February 19, 2013 Leave a comment

This is really interesting!!! Can’t wait to try it out, I just got Azure up and running with a couple of VM’s in it and will set this up and try it ASAP! 🙂

CloudBridge Connecting to Microsoft Azure

Release Date: Feb 15, 2013

 
Citrix CloudBridge connects enterprise datacenters to external clouds and hosting environments, making the cloud a secure extension of the enterprise network.

This technology preview offers standard based secure connectivity to Microsoft Azure. With this enhancement, a customer can  connect their enterprise data center to the Azure VPN gateway and access the IaaS and PaaS offerings from Microsoft. 

The following are the key points to note :

  • Secure L3 connection to Azure VPN gateway
  • CloudBridge deployment on the enterprise data center only. It is not running inside Azure
  • No WAN Optimization or L2 extension supported in this solution since it needs deployment of CloudBridge on the Azure end as well.

Images and Licenses:

We are making available virtual appliances running on XenServer (xva images). These appliances need EVAL licenses. Please follow links to sign-up and get these EVAL licenses.
