Likelihood to Recommend Citrix Netscaler can be a powerful network appliance for environments that are fully committed and open to utilizing a network appliance that isn't made by a traditional network vendor. Administrator user experience has improved over the years and will continue to improve with the flexibility of virtual and physical appliances available for medium and large enterprises.
Read full review [NGINX] is very well suited for high performance. I have seen it used on servers with 1k current connections with no issues. Despite seeing it used in many environments I've never seen software developers use it over apache, express, IIS in local dev environments so it may be more difficult to setup. I've also seen it used to load balance again without issues.
Read full review Pros Flexibility. NetScaler assumes its admins know a bit about networking and in-depth details surrounding the applications they are configuring access for/to. This being so, the range of configuration options is very broad allowing various versions' combinations of protocol patterns, expressions, rules etc., all to the benefit of the admin. Granularity. Having such a broad range of configuration options available, while still allowing simple options to be configured simply. The GUI is well-stylized and navigation has a good flow. Ease of control. For load-balancing of simple services right out of the box, NetScaler makes it pretty easy, compared to the range of options available in the surrounding GUI and under the hood. Read full review Very low memory usage. Can handle many more connections than alternatives (like Apache HTTPD) due to low overhead. (event-based architecture). Great at serving static content. Scales very well. Easy to host multiple Nginx servers to promote high availability. Open-Source (no cost)! Read full review Cons The documentation could use an overhaul with specific examples related to the command line as well as GUI. Explanations in the documentation would also be helpful. Being able to have more than just one routing table would allow the ability to leverage security. Read full review Customer support can be strangely condescending, perhaps it's a language issue? I find it a little weird how the release versions used for Nginx+ aren't the same as for open source version. It can be very confusing to determine the cross-compatibility of modules, etc., because of this. It seems like some (most?) modules on their own site are ancient and no longer supported, so their documentation in this area needs work. It's difficult to navigate between nginx.com commercial site and customer support. They need to be integrated together. I'd love to see more work done on nginx+ monitoring without requiring logging every request. I understand that many statistics can only be derived from logs, but plenty should work without that. Logging is not an option in many environments. Read full review Likelihood to Renew Great value for the product
Read full review Usability Improve on the specifics I mentioned previously and could be a 10/10 product. It is also a confusingly branded product that I have supported in two large enterprises where IT departments are unsure if the product belongs to the Citrix remote access support team or the Network infrastructure support team (it should be the later) and typically under utilized.
Read full review Front end proxy and reverse proxy of Nginx is always useful. I always prefer to Nginx in overall usability when you have application server and database or multiple application servers and single database i.e. clustered application . Nginx provides really good features and flexibility which helps the system administrator in case of troubleshooting and also from the administration perspective . Also, Nginx doesn't delay any request because of internal performance issues.
Read full review Support Rating Overall, our organization's experience with Citrix support is that support can be hit or miss. Oftentimes it takes multiple attempts and much longer than desirable to obtain a viable solution for issues experienced with their products. It would be great to see Citrix invest time, effort, and almighty dollars into improving their support and bug fix process across the board.

Read full review Alternatives Considered We chose Citrix ADC over Kemp and F5 due to additional integrations with various products such as Citrix/Horizon/Monitoring tools. We additionally chose ADC due to better ease of use and ability to have the appliances be virtual or physical, with the configuration being a simple migration of code which provided flexibility to be able to do a hybrid environment with ease.
Read full review We have used Traffic, Apache, Google Cloud Load Balancing and other managed cloud-based load balancers. When it comes to scale and customization nothing beats Nginx. We selected Nginx over the others because
we have a large number of services and we can manage a single Nginx instance for all of them we have high impact services and Nginx never breaks a sweat under load individual services have special considerations and Nginx lets us configure each one uniquely Read full review Return on Investment It has saved a tremendous amount of money and manpower by allowing for broad support without the need for a VPN. The security functions within Netscaler enabled our business to pass additional IT-based audits. Having a full Citrix stack from front to back makes our business look more professional both to our users and outsiders. Read full review Nginx has decreased the burden of web server administration and maintenance, and we are spending less time on server issues than when we were using Apache. Nginx has allowed more people in our company to get involved with configuring things on the web server, so there's no longer a single point of failure ("the Apache guy"). Nginx has given us the ability to handle a larger number of requests without scaling up in hardware quite so quickly. Read full review ScreenShots
