One Content Switch to rule them all!

One content switch to rule them allThe Content Switch (CSW) is a beautiful feature that enables you to use a single point of entry – your NetScaler – to host multiple services (like XenDesktop, XenMobile and Sharefile). Based on the content (and context) requested the CSW will direct the traffic to the server offering the best service suitable for the task.

Since I visit sites that restrict outgoing traffic to known ports (sometimes only port 80 and 443), and only have a single IP in my home lab, I needed a solution that allows me to demo several Citrix products using the same entry point. In this article I’ll show you how you can use the CSW to host several Citrix products (XenDesktop, XenMobile and ShareFile) using a single IP and port.

Citrix NetScaler: DSR, a poor man’s load balancing solution

Gartner Magic Quadrant for Application Delivery Controllers 2013There are occasions where you need a good load balancer but don’t have the budget. Microsoft offers Network Load Balancing services (NLB) as part of their Windows server operating systems, but although we’re looking for a cheap solution we try to avoid problems. This is where the Citrix NetScaler comes in. Gartner positioned the NetScaler ADC in the leaders quadrant of the Magic Quadrant for Application Desktop Controllers (for the 7th consecutive year in 2013), proving it to be good solution and a reliable partner. Using Direct Server Return (DSR) mode we can offer a “poor man’s solution”.

In this article I’ll explain why you might (not) want to implement Direct Server Return (DSR), how it works and of course how to configure it!
