Comparison of Apache and nginx

Advantages of nginx over apache:

●Lightweight, also serves web services, and takes up less memory and resources than apache

● Anti-concurrency, nginx processes requests asynchronously and non-blockingly, while apache is blocking. Under high concurrency, nginx can maintain low resources, low consumption and high performance

● Highly modular Designing and writing modules is relatively simple

● The community is active and various high-performance modules are produced quickly

● Nginx supports more concurrent connections and can support up to 50,000 concurrent connections

● The version can be upgraded without interrupting the service, and can run uninterrupted (7*24)

● The static processing performance is higher than apache

The advantages of apache over nginx:

● Rewrite is more powerful than nginx’s rewrite

● There are so many modules that you can basically find everything you can think of

● Few Bugs, nginx has relatively many bugs, apache has a more mature technology and development community

●The dynamic processing performance is higher than nginx

The core difference between the two is:

Apache is a synchronous multi-process model, and one connection corresponds to one process; nginx is asynchronous, and multiple connections (10,000 levels) can correspond to one process.
