Difference between nginx and httpd in terms of functionality and performance

LINUX (Fedora)
QUESTION 1
Apache (httpd)
Apache is the server in LAMP stack. LAMP still remain the most popular stack even though there is
so many web stack available in the market nowadays. It contains many sets of features which are
available through the installation of about 60 official modules or even unofficial modules which
both exist. Apache can be configured through three main multi-processing modules such as process
model, work model, and event model.
NGINX
NGINX is a web server which was mainly created to handle at least 10,000 clients who connect to a
singer server simultaneously. It employees asynchronous, event-driven architecture to enable it to
control and handle massive amounts of server connections at a go.
Difference between nginx and httpd in terms of functionality and performance
NGINX and Apache (httpd) can be compared in several ways such as:
1) Performance
They both perform in static and dynamic roles. NGINX is the best option in high concurrency levels
in static content since it servers such contents much faster than Apache. NGINX is much faster. In
dynamic content performance, both have similar results in serving dynamic content.
2) Security
They all have smart security track. However, there are few cases of vulnerabilities reported but they
can be solved by configurations of DDoS attacks handling.
3) Flexibility
Apache leads in flexibility as compared to NGINX. Customization by Apache can be done by just
writing the modules since it has dynamic modules which can load for the longest time. However,
NGINX requires an admin to compile binary modules. Apache wins here also.
