NetScaler Gateway vs. NGINX

The best usage scenario for Citrix Netscaler Gateway is in enterprises with a high volume of telecommuting users or in situations where the user needs to access certain applications from anywhere. In our case as a hospital, we need our doctors to access the medical records of the patients and be able to carry out any required action, with a high level of security and with a certain agility.

[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.

• allows seamless use of 2-factor authentication for heightened security within the VPN, and lowers risk of an external hack because of it.
• it allows for differing levels of security. access can be set specifically through the VPN so 2 users can use the same site and get different results depending on their active directory security policy.
• It can grant the ability to launch a single application or an entire VPN envelope

Incentivized

• 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)!

• I suggest make it more faster because sometimes its lagging but not all the time.
• When it comes to Notepad I suggest having options for the size of fonts, and color of fonts, to make it look nicer.
• I suggest making it more user-friendly, and more features so that users can perfectly maximize this tool.

• 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.

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.

Support is pretty good and pretty fast to respond. I can't say I can really complain about the support experience I've had with them, as they've resolved issues within a reasonable time-frame. Of course, they could always be faster and better, but I think for what we pay, it's well worth the money.

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.

The only other SSL VPN type product I have used was Citrix Secure Gateway. Netscaler is a MUCH more feature filled product. CSG was a free add on to older versions of Citrix Metaframe and XenApp and was specifically just used for securing Citrix infrastructure. Netscaler excels in securing Citrix but can also be used to secure shared apps of all kinds regardless of how they are published. I did do a test run on 2X's product which did include a secure gateway but then base 2X product was not really comparable to Citrix so did not go too far with it.

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

• Our data is secure and protected from the outside world which is priceless.
• It saves our business money as we can provide our clients with a safe and secure alternative to accessing their data remotely rather than having to take the more expensive route of travelling on-site to gather the data we need.
• It gives us the opportunity to host on-site training using gated cloud based environments which enhances our business services. The ability to easily change access information, such as a password, after administering a training course gives us the flexibility we need to provide and subsequently restrict access to our training environments to suit our needs.

• 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.
