A lot of our customers have moved from Apache. Apache has a scalability issue and a concurrency issue.

We previously used Apache. We switched for security reasons and because Apache couldn't be upgraded. It had a lot of security vulnerabilities.

I used HAProxy before NGINX and I switched to the latter because of the documentation.

We did previously use a different solution for two or three years. We needed to have some security features, which made us move to NGINX.

We are still using F5.

We tried to use some "golden bullet" solutions but we never needed most of their features (like a built-in database environment). NGINX is a direct way to satisfy a specific need.

We previously used Apache2. We switched to NGINX because I read about the better throughput that NGINX offers.

Before NGINX, there was Squid. I have been using NGINX since its arrival on the market.

Squid is a tool of a different age, from a different (previous) generation. I started using Squid many years ago, from its pre-release beta. It was a good tool for its time and purpose: just caching proxy, which allows you to somehow save on traffic and bandwidth. At these times, the web was mostly static so it worked.

Later, both the capacities of the channels had grown 1,000-10,000 times from megabits to a 10th of gigabits per second. The web moved to mostly dynamic content, so caching proxies lost their appeal.

On the other hand, NGINX is mostly an application level gateway, not a proxy per se. It is a different tool for different tasks.

When I was young, I used Apache2, because that is all I knew. I switched to NGINX once I learned of it. That's the story. 

Previously, we used Apache and another solution, but I can't remember the name. It took roughly 30 minutes to scale up and down; that's one of the reasons why we switched to NGINX.

First, I used NGINX as a reverse proxy web server for Apache.

We used Microsoft ForeFront and changed because it was not stable during DDoS attacks.

Yes, Apache. It was terribly complex for usage and unstable in a production environment.
