Imperva CDN vs. NGINX

I recommend it as a WAF, but not as a CDN. There are better CDNs, in my case I use transparentCDN (now www.transparentedge.eu) and Edgecast (now Verizon CDN).

[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.

• Reliability / Uptime
• Security

• 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)!

• CDN functionalities are secondary and cannot be compared to a top-level CDN.
• The WebGUI interface of the dashboard is very improvable. They have been changing the UX for years and it is disjointed and with services that have not yet been migrated.
• The analysis of WAF attack logs is insufficient. It is difficult to analyze attacks of past hours, event filters are missing. It is complicated to analyze the chronology of an attack.
• There are extra modules to improve the attack logs analysis but they are expensive and add little.

• 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.

Great value for the product

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.

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.

Also TransparentCDN (now www.transparentedge.eu ) and Level 3

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

• It's an expensive product if you have a lot of traffic volume, but I feel confident with their WAF.

• 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.
