I am a reseller. A lot of customers use this solution on cloud and on-premises. Typically, people use NGINX to build their own CDN solutions, so it often goes into CDN deployments. Most apps have NGINX OSS as the underlying base, whether they're cloud apps or on-premises apps. NGINX is the free version of NGINX Plus.
F5 is now creating buzz in the market because if you migrate to NGINX Plus, you'll get a 30 minute response time from F5 or the NGINX team if you have any challenges with the solution, so that's an advantage.
NGINX Plus can give you multiple features from a load balancing perspective. The standard NGINX OSS doesn't have that.
There are about 400 million websites that run NGINX OSS. Since NGINX was an open source company until F5 acquired it in 2019, NGINX doesn't have a lot of paid products. In the last year and a half, the F5 and NGINX teams have started doing the sales pitch for people to upgrade to the paid version, like Red Hat, which has an open source version and a paid version. We're seeing good uptake, but I don't think they have been able to cover more than 10% of the user base.
For most of the companies I have interacted with, 90% of them are using NGINX because it's a favorite open source solution. People are now using NGINX Plus because F5 just started selling it in the last year and a half. Out of the 90% who are using it, there are about 10-15% who are using the paid version.
