Aside from continuously being compared to Apache, NGINX is also being compared to another rival, the Microsoft IIS. Some of you might want to know more information about them both, which is why we made this comparison. With no further delay, please read our article below.
In this article we are going to give you information about:
– What is NGINX and IIS
– What NGINX and IIS is capable to do
– NGINX vs IIS
NGINX is an open source web server that is also used as reverse proxy, load balancer and HTTP cache, which was created by Igor Sysoev and released to public since 2004 and in 2011 a new company with the same name is founded to provide support. NGINX is released under the terms of BSD-like license. NGINX is also used as load balancer by a large fraction of web servers. Just under Apache, NGINX is the second most popular open source web server in the world. According to a Web Server Survey conducted by Netcraft in 2016 shows that NGINX is used by 18.22% by all active sites and 27.83% used by top million busiest sites. If you are interested on other web server, read our article on Haproxy vs NGINX here.
NGINX was initially created to handle the C10K problem, which means it can handle a high amount of continuous connections and moreover lessening the amount of hardware consumes. NGINX also has been proven to be faster than the most popular web server now Apache. NGINX is continuously upgrading their features and enhancing their performance, such as native reverse proxy support and advance caching techniques, which able to convert proxied dynamic content to static content in an attempt fastening the caching. The most useful of the among is the easy to use built-in load balancing that will evenly distributes incoming network traffic to all backend servers.
IIS or Microsoft Internet Information Service is a web server made by Microsoft to be used in Windows NT family; it supports HTTP, HTTP/2, HTTPS, FTP, FTPS, SMTP and NNTP. Almost all of IIS version is released either with alongside or with a version of Microsoft Windows. The newest IIS version is included in Windows Server 2016 and Windows 10, which include support for HTTP/2. IIS shows consistently falling trend since February 2013. Currently IIS is the third most popular web server use in the world, behind Apache and NGINX. A new Netcraft data in February 2017 indicated that IIS is used by 10.19 % of top million busiest sites.
Taken by microsoft.com, in the IIS 10.0 Version 1709, which is the latest version of Internet Information Services. There are some improvements delivered to its user together with Windows 10 Fall Creators Update. Those updates are the improvement of HTTP Strict Transport Security (STS) that allows a website declares itself as secure host and to inform browsers that the website should only be accessed through HTTPS connections. This version has turn-key support for enabling HSTS without needing error-prone URL rewrite rules. This version also introduces new server variables for Cryptographic Protocol, the Cipher algorithm, the Key Exchange Algorithm, and the Message Authentication Algorithm.
Other plus comes with this updates is the container enhancements, which allow the user to run the IIS worker process (w3wp.exe) and changes directly to the Central Certificate Provider or also called CCS that will make it more amenable for running in containers.
NGINX vs IIS
|- Linux based web server||- Windows based web server|
|- Faster than IIS||- Not as fast as NGINX|
|- The second most popular web server||- The third most popular web server|
|- Have built-in load balancer||- Doesn’t have built-in load balancer|
When you comparing the performance between NGINX which based on Linux and IIS, which based on Windows, there must be some differences. For example the speed, which is won by NGINX. But if you code with .NET, it is better to choose IIS. IIS security used to be vulnerable, but they continuously upgrading it, so it may catch up to NGINX in the future. All in all, we will still recommend you to use NGINX, since the reason it is being in the second place above IIS is because it works.
