    Apache HTTP Server

    As I mentioned earlier, the Apache HTTP Server has a small disadvantage compared to the competition (NGINX) in terms of performance. If you run websites that really have a lot of visitors, NGINX might be the better alternative.
    On the other hand, the Apache HTTP Server is open source and free. Further functionalities can be activated via modules. The documentation is really excellent.

    Microsoft IIS

    IIS as a web application server is perfectly suited for .net, .net core, asp.net applications. Our core ESB runs on IIS and has hundreds of gigabytes of data moved through it every day spread across millions of transactions. We have other mission critical applications that deliver our results to patients and doctors relying on IIS web application servers. If you stay in the Microsoft development stack, IIS is a top tier, efficient, and reliable web server.

    Pros

    Apache HTTP Server

    • Street Cred: Apache Web Server is the Founder for all of Apache Foundation's other projects. Without the Web Server, Apache Foundation would look very different. That being said, they have done a good job of maintaining the code base, and keeping a lot of what makes Apache so special
    • Stability: Apache is rock-solid. While no software is perfect, Apache can parse your web sources quickly and cleanly.
    • Flexibility: Need to startup your own Webpage? Done. Wordpress? Yup. REST Endpoint? Check. Honeypot? Absolutely.

    Microsoft IIS

    • A big advantage that we use all the time is reviewing the logs that automatically get generated in IIS. It has helped us troubleshoot various problems in our applications over the years.
    • IIS integrates really well with Visual Studio and TFS. We are able to quickly deploy new applications and changes to applications when requested by the business.
    • IIS has proven that it is easy to configure and maintain with minimal effort.

    Cons

    Apache HTTP Server

    • The default configurations which comes with Apache server needs to get optimized for performance and security with every new installation as these defaults are not recommended to push on the production environment directly.
    • Security options and advanced configurations are not easy to set up and require an additional level of expertise.
    • Admin frontend GUI could be improved to a great extent to match with other enterprise tools available to serve similar requirements.
    Rahul Dhangar | TrustRadius Reviewer

    Microsoft IIS

    • There are some hidden and not very easy to find configurations that would have been better if completely left out, like machine.config. I understand the idea, but sometimes things are easier without trying to make things easy for you.
    • After 15 years of usage I still don't understand why IIS sometimes complains that I already used my *.domain https certificate for another website in the same domain.
    • There are too many versions... IIS should be a product with almost no other functionality than being a web server. It's not necessary to have imcompatible versions.

    We have no intention to replace all applications running on top of the IIS platform. Not all applications support other platforms and not all support staff are skilled in Linux/Apache platform support. Whereas IIS may not be the best performing or most secure web platform available, for the aforementioned reasons, it is impossible not to continue use of this product.

    As I've mentioned earlier, Microsoft IIS is very simple and easy to use. The user interface is a little bit overloaded with a huge number of different options, but once you have a little clue of what you are doing and what you need - no issues at all.

    ARR (application request routing) in Microsoft IIS Server enables the web-admins to increase the web app reliability and availability through the rule based routing and load balancing of HTTP requests which in turn provides highly available server. IIS 7.0 Manager also provides kernel as well as user mode caching for faster performance and in case if the server fails, the IIS server has good amount of details logged in its log files which help understand and debug the cause quickly. Load balancing facilitates IIS server to fight against availability issues.

    In my experience, I have never had significant issues with IIS performance. Sometimes I've experienced issues with loading time, but it is mostly related to the web site code. However Amazon, Microsoft and Google providing free cloud services with very limited resources, and in that scenario, "heavy" websites on IIS could be the issue. In other situations - performance is good.

    I give this rating because there is so much Apache documentation and information on the web that you can literally do anything. This has to do with the fact that there is a huge Open Source community that is beyond mature and perhaps one of the most helpful to be found. The only thing that should hold anyone back from anything is that they can not read. RTFM, my friend. And I must say that the manual is excellent.

    As mentioned earlier there is so much documentation or guides or stack overflow questions out there that someone will have faced the same or very similar scenario to what you are going through that you will almost certainly find a solution to what you are after.

    Alternatives Considered

    Apache HTTP Server

    I has a lot more features, except that IIS is more integrated in a Windows environment. But now with .net core also possible from Apache it would work anywhere really. Only in a full Windows environment where full integration is needed I would chose to go for IIS. Otherwise Apache it is.

    Microsoft IIS

    In my experience, Microsoft IIS was definitely easier to wrap my head around and also to troubleshoot. The GUI was a great visual way to see what "sites" and "app pools" you have, what is running, what is currently up.
    Microsoft IIS also offers the flexibility to have multiple sites and app pools going at the same time and also the versatility to do maintenance on any one without affecting the others.

    Microsoft IIS Server is scalable if the underlying server configuration is done correctly. Use x64 edition v/s 32bit and using 32bit mode application pools are some of the tweaks to be done to make the IIS server scalable. There are too many small configurations need to be carried out in order to make a highly scalable IIS server hence not giving full score in this area.

    Return on Investment

    Apache HTTP Server

    • Works as intended, so it's less to worry about.
    • Works great on elastic environments (like EC2).
    • As an Open Source project, you can get support for almost any problem you can have.
    • Configuration files, while powerful, can be tricky to dominate for some.
    Anonymous | TrustRadius Reviewer

    Microsoft IIS

    • Allowing us to internally host our monitoring websites allows quick access to data that can be quite hidden, saving developer time.
    • It was inexpensive compared to more bulky solutions saving upfront cost.
    • It’s easy to install and enable allowing more developer savings.
