Citrix NetScaler SD WAN – What is It? | Parallels Insights

What Is Citrix NetScaler SD-WAN? 

citrix netscaler sd wanCitrix NetScaler SD-WAN (software-defined wide area network) or NetScaler SD-WAN is the old name given by Citrix to a set of physical, virtual, and cloud-based appliances. They were designed to combine multiprotocol label switching (MPLS) connections with other network links like broadband, LTE, and wireless in order to provide end-users with the best user experience possible. The product was rebranded in 2018 and is now known as Citrix SD-WAN.  

How is Citrix SD-WAN used in businesses and organizations? 

Citrix SD-WAN is often used as one of the many components comprising Citrix’s complex virtual application and desktop delivery solution. You will usually find it deployed alongside other Citrix products like Citrix Virtual Apps and Desktops (which itself also consists of several components like Citrix Delivery Controllers, Studio, Directory, StoreFront, etc.), Citrix ADC, Citrix Gateway, and others.  

Each of these products have their own roles in virtual application and desktop delivery. The role of NetScaler SD-WAN or Citrix SD-WAN, as mentioned earlier, is to combine various connections to ensure a good user experience. In most scenarios, organizations will have an MPLS connection, which they’ll use for delivering their virtualized applications and desktops to remote branches and end-users.  

Once the demand starts to grow and the MPLS’s capacity fills up, the organization will have to look for ways to remedy the situation. Otherwise, application response times and the overall user experience will suffer. This is where SD-WAN comes into the picture. Organizations typically deploy SD-WAN to augment their MPLS connection with broadband and other links to improve the user experience.  

Do you really need Citrix SD-WAN? 

It depends. First of all, you need to bear in mind that a Citrix SD-WAN appliance doesn’t come cheap. A single Citrix SD-WAN WANOP Edition VPX 200 Mbps On-Premises Subscription License can run up to $28,000.  

Secondly, if your virtual desktop and application delivery solution is already architected for delivering a great user experience, you may no longer need Citrix SD-WAN at all. One particular solution that does this is Parallels® Remote Application Server (RAS).  

Parallels RAS- A Citrix alternative

Parallels RAS is already designed to provide virtual desktops and applications that have quick response times and excellent performance on any device. Best of all, Parallels RAS is a single solution—it doesn’t require additional products like Citrix does. In addition, you can set up one or more high availability load balancers (HALB) without any extra cost in a few simple steps.
