Different types of web servers

In openmarket there are different types of web servers available. Let's discuss about the most popular web servers.  Apache, IIS, Nginx and LiteSpeed are few of them.

Apache web server

One of the most popular web server in the world developed by the Apache Software Foundation. Apache is an open source software which supports almost all operating systems including Linux, Unix, Windows, FreeBSD, Mac OS X and more. About 60% of machines run on Apache Web Server.

Customization of apache web server is easy as it contains a modular structure. It is also an open source which means that you can add your own modules to the server when to require and make modifications that suit your requirements.

It is more stable than any other web servers and is easier to solve administrative issues. It can be install on multiple platforms successfully.

Recent apache releases provide you the feasibility of handling more requests when you compare to its earlier versions.

IIS web server

Microsoft developed this product and they maintains, thus it works with all the windows operating system platforms. Also, they provides good customer support if it had any issues.

Nginx web server

Another free open source web server is Nginx, it includes IMAP/POP3 proxy server. Nginx is known for its high performance, stability, simple configuration and low resource usage.

It is getting popular in the recent times and it is hosting about 7.5% of all domains worldwide. Most of the web hosting companies are using this in recent times.

LightSpeed web server

LiteSpeed (LSWS) is a high-performance Apache drop-in replacement. LSWS is the 4th most popular web server on the internet and it is a commercial web server. 

Upgrading your web server to LiteSpeed will improve performance and lower operating costs.

This is compatible with most common apache features, including mod_rewrite, .htaccess, and mod_security. LSWS can load apache configuration files directly and works as a drop-in replacement apache with most of the hosting control panels. It replaces apache in less than 15 minutes with zero downtime.
