NGINX, a business unit of F5 Networks, powers over 65% of the world's busiest websites and web applications. NGINX started out as an open source web server and reverse proxy, built to be faster and more efficient than Apache. Over the years, NGINX has built a suite of infrastructure software products o tackle some of the biggest challenges in managing high-transaction applications. NGINX offers a suite of products to form the core of what organizations need to create…
Other products such as the Barracuda Load Balancer and NGINX Plus were considered, but not tested. Since our group uses other Citrix solutions, we wanted to go with a unified and integrated approach.
NGINX's footprint is much smaller than Apache, and it's great for serving up static content. The URL rewriting was not as familiar as Apache, but just as powerful once configured correctly. As a load balancer, it's much more affordable than Citrix ADC. We used the load …
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.
[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.
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.
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.
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.
I gave the NetScaler a 7 here because the system once configured and deployed is very easy to use. However, if you did not deploy the system and do not have the fundamental background knowledge then you will have trouble using the product in general. Overall it is a great product and service but does typically require professional services to be deployed.
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.
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.
Community support is great, and they've also had a presence at conferences. Overall, there is no shortage of documentation and community support. We're currently using it to serve up some WordPress sites, and configuring NGINX for this purpose is well documented.
easy to use and setup and reliable. Once the configuration was setup and running this has been really useful and easy to maintain. The other solutions seemed overly complicated and difficult to configure and get up and running with the security that we required
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
We had this set up before COVID and it saved us. We just added user licenses and scaled out our citrix farm and IT sat back and just monitored users from home.
Scales up and out with ease
Challenging to find NetScaler experts for advanced features you want to enable and use
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.
