“One of the main benefits of Citrix SD WAN surrounds their single code base, which is a set of standard software and service components that are shared across the company's product portfolio.

The Citrix single code base offers their customers seamless integration of SD WAN & SASE into the same management interface.

With the majority of IT teams beginning their research with SASE security, it's worth knowing that Citrix offers a complete security stack: next-generation firewall Microsoft cloud access security broker and AI-driven forensics. Although these features are standard components of any SD WAN/SASE solution, Citrix is investing heavily in roadmap enhancements.

What is the Citrix SD WAN use case for improving application performance?

Application path performance spans per-app QoS (Quality of Service) to prioritize traffic. For example, Citrix virtual apps are prioritized and routed based on standard pre-configured policies which is the enabler to fast start capability. Overall, application performance is covered by:

  • Intelligent Path Selection - Provides a higher level of link availability for uninterrupted access to applications.
  • Dynamic Virtual Paths - offers the ability to select paths based on the current state of application performance.
  • Visibility of App Performance - important insights into applications over time which may cause user issues.
  • Centralized Management - Enables Citrix customers to manage the solution across DIY, Co-Managed for Fully managed services.

Citrix provides comprehensive support for device connectivity with provisioning based on discovery by scanning wireless networks within range. If WiFI signal strength or wired internet connection speed can't be detected, the SD WAN appliance or software will automatically discover an available network to connect to establish the VPN tunnel. Once the VPN has been established, devices are automatically connected back through their original network connections as they come online at each location. Citrix SD WAN can helps to bridge the gap between primary sites to provide business continuity during disasters or other outages that disrupt connectivity. Citrix also offers bandwidth scalability by using variable bit rate encoding standards and packet prioritization algorithms that adapt seamlessly to changing traffic loads.

What is the Citrix SD WAN use case for security?

The more exciting element is the out-of-the-box recognition of SaaS and typical applications that allow security policies to deploy in minutes. With cloud-based AI intelligence, the applications' database is constantly undergoing updates that will automatically deliver updates to your security policies.

Citrix cloud services are essential for securing Internet access across all users regardless of location. In their WAN edge report, Gartner pointed out that Citrix is heavily investing in both security and cloud integration, which are the two most important areas for any business in 2021 and beyond.

What is the Citrix SD WAN use cases for disaster recovery (DR) and business continuity (BC)?

Citrix SD WAN provides an additional layer of protection to the data center. This is done by replicating the application and database from a primary site, situated at another location in case disaster strikes. It also ensures that any Internet disruptions or service outages won't impact the business which is typically the case with traditional methods such as VPNs connections, where if one goes down, then all traffic is affected because they are dependent on each other for functionality. The SD WAN architecture for Citrix discusses 3 methods of setting up disaster recovery, which includes edge mode, inline mode and virtual inline mode.

“The premium product allows IT teams to see the state of any network node at any time, making it easier to detect problems before they escalate into full outages.

Citrix offer three main products based on 1 and 3 year licensing agreements.

The premium product allows IT teams to view the state of any network node at any time, making it easier to detect problems before they escalate into full outages. Data centers have historically suffered from cascading failures that took hours or even days to resolve because it was nearly impossible for operations teams to visualize what had happened in an outage sequence across many complex systems (including vendor equipment). The Citrix SD WAN service is designed to manage data center and cloud through:

  • Monitoring and analytics.
  • Performance assurance.
  • Optimization through end-to-end bandwidth optimization.
  • Quality of experience monitoring, troubleshooting and management tools.

Netify notes that some publications are suggesting that Citrix have a limited networking history and no real prior capability. While this statement is true, software-WAN is somewhat changing this outlook as the WAN becomes more about code than physical hardware devices with hard to manage operating systems.
