Quotes From Members Comparing Citrix NetScaler ADC vs. NGINX Plus

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
Pros
It is the best product out there.It has an easy user experience and user interface. The security is effective and better than its competitors.This product protects us from Internet attacks using its firewall features to block any attacks.Scalability is great. One of the best features of NetScaler is that it can scale out.This solution allows the user to easily scale out application delivery, and provides secure remote access.One feature that works really well is the SSL VPN. It's very easy to set up and you can go very granular with it. You can define what user groups get what kind of access and the management overhead is very low.I like the monitoring ability as it enables me to identify when an internal (load-balanced) resource is having issues before it becomes a problem in production.Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature.

Its most valuable features are load balancing and application delivery. This is the most efficient application for these features because of stability and its efficiency.NGINX works much better than HAProxy in our current hardware and architecture for HTTP/HTTPS load balancing. ​​The robust software architecture allows for it to be scalable and very stable.​The flexibility of its modules allow it to be scalable.​​Zero Downtime has always been a strength in recommending infrastructure web services. NGINX allows me to execute such infrastructure with less complications and the ability to switch from server to server easily.​When I worked in a security research center, we tested NGINX to support DoS and DDoS attacks, and its results were great.Valuable features include authentication, caching, reverse proxy routing, and load balancing.The best solution, by far, for web traffic control for things in production and just around the house.

Cons
It can be difficult to setup.We would like to see more monitoring features going forward, because the current product monitoring options are not enough for security usage.I would like to see more integration for single sign-on.Should offer more flexible cost-effective licensing for small to medium sized organizations.The customization has always been a key area where some improvements are required. In the beginning, everything was for customizing the outer shell of it. You had to use the command-based utility and you had to do a lot of manual work. They have improved it a little bit and now there are some GUI-based functionalities that can be used. However, more can be done that doesn't require a lot of intervention. Right now there are some features, there are some customizations that can be done, but it's still very tedious, very cumbersome, a lot of work. So that could be simplified.In every release - and it doesn't matter if it's a minor release or a major release - they keep moving things around and they keep changing the mechanism. So certain things can work in one version one way, and everything works really well, then when you upgrade it to the next version, it breaks everything because they have a new way of doing it.Development team's response time could be better.Needs configuration processes like disabling LB VIPs, automatically disabling the IPs used.

They should do in the open source version of what they did to Advanced HTTP, TCP, and UDP load balancing.Our most challenging part was to run an older PHP website reverse-proxied through NGINX. That was not fun.If NGINX brings some features for health check in the open source version, it would be better. ​Make modules easier to enable or disable. The beauty and ugly side of the NGINX modules is you have to know how to compile the module. For beginners or non-very technical aspirant(s) going for NGINX, they have to learn how to compile the modules.​I would like it to have a more user-friendly graphical interface.The biggest room for improvement would be to allow NGINX Core machines to cluster for memory zones in some way with a plug and play module. ​Only improvement needed that I would point to is scalability. With it, I mean clusterized organisation on a low level. At the moment, the best alternative is RHEL HA.

Pricing and Cost Advice
I do not have any experience with the pricing of the product.We are quite happy with price. It's not too high.The licencing model that we bought has been good. The licencing model is more flexible.We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them.It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high.It all depends on the features that will be used and the number of accesses.Costly product and complicated licensing.It's not for startups or SOHO.

​NGINX is a free tool in Brazil. There are some companies which do support it.​The price is the cost to contract support with a specialized company, usually during consulting hours.​​NGINX Plus is worth it, if you need it. If you do not need the features or support, the free and open source package is more than capable. ​I am not so happy with their pricing policy, but this is not the worse thing in my life. I can tolerate it.Nginx is free. I don't have experience with the Plus version.
