Apache and Nginx happen to be the two most reckoned within the web server business. The first difference between them is that Apache is an open-source HTTP server; meanwhile, Nginx is a reverse proxy server and an asynchronous web server of high performance. Bug fixes, application development, and support in Apache HTTP server is being coordinated by Apache Software Foundation and maintained and managed by a community of users around the world.
On the other hand, Nginx Company, which was founded in the year 2011, handles the maintenance and support of Nginx. Another key difference between them is the way they handle the request of clients. Varieties of multiprocessing modules are provided by Apache to handle web traffic and clients' requests. Nginx uses minimal hardware resources to handle several clients' requests simultaneously. In the Apache HTTP server, just a connection has a single three associated with it. Meanwhile, Nginx can handle several connections with a single thread.
