Executive SummaryUpdated on Mar 5, 2025

IIS and Apache Web Server compete in the web server category. Apache seems to have the upper hand due to its open-source nature and cross-platform compatibility.

Features: IIS integrates seamlessly with Windows and offers robust security with application pools and process isolation. It is easy to use for Microsoft ecosystem users and provides performance benefits when hosting applications. Apache, known for stability and flexibility, is the most widely used web server worldwide. It is open-source, supports multiple operating systems, and efficiently handles extensive client requests.

Room for Improvement: IIS faces compatibility issues outside Microsoft environments and can be challenging to scale. Troubleshooting is not intuitive for unfamiliar users. Apache requires detailed command-line configuration, which can be daunting for less experienced users. It lacks support for the .NET framework and structured customer support outside certain areas.

Ease of Deployment and Customer Service: IIS is often deployed on-premises or in hybrid cloud setups, benefitting from Microsoft's support ecosystem, although initial support levels may vary. Apache's deployment is versatile but often relies on community support due to its open-source nature, making official support less straightforward.

Pricing and ROI: IIS incurs costs from Windows Server licenses, making it economically viable for organizations already using Microsoft products, with users reporting strong ROI from integration benefits. Apache, being free, offers significant cost savings, though ROI varies greatly depending on implementation and hardware expenses.

Enterprise Architect at Smals vzw

Faced limitations with integration and long-term adaptability but benefited from a lightweight architecture for standalone applications

I find valuable and beneficial the independence that comes with Apache Web Server. You can build a small project using a simple application server without bothering too much about how to manage it. The compatibility with multiple operating systems has helped my operations since most of the time we use Linux. Some systems rely on Windows, but they are few; in the past, Windows was the dominant operating system for mainstream PCs and infrastructure, but not for business. All the companies I worked for had 90% Linux and maybe up to 10% Windows. The initial setup of Apache Web Server was straightforward and okay.

Designs and manages multiple websites while ensuring data backup and disaster recovery

I have experience with AWS, and I am most familiar with the server environment, as we just use the server environment and then use Microsoft products on an AWS environment. I have experience with Windows Server IIS, which I ran on my own on-premise data center. The website was developed and then hosted, and through IIS, we managed the servers. The manageability within the IIS environment is not very difficult. For server management, you need to ensure data backup, data restore, and you have a DR configured to keep the database intact. It was done on-premises, so I had no problem doing that. If you have to go to the cloud, then you should have the storage connected to the IIS server and also have a DR set up for that. I didn't use Microsoft Azure tools, but since it is a Microsoft product, Azure has all the portability, so you don't have to worry about compatibility on the cloud. On a scale of 1-10, I would rate this solution a 10.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Apache Web Server can be used as a proxy server"

"The most significant advantage is the ability to swiftly enable HTTPS services when my DNS is configured correctly."

"The solution's most valuable feature is reporting."

"The control panel is very easy to navigate. It's similar to most hosting platforms, so it's user-friendly. Once you get used to it, managing your hosting becomes easy, too."

"The best thing about Apache is that it is open-source, so implementing my platform on-premises is less expansive than other solutions."

"Apache Web Server is free of cost."

"The solution is extremely stable; we haven't had any issues with bugs or glitches and it doesn't crash or freeze, so it has been reliable."

"Its community is its most valuable feature, and solving problems is easier on Apache because so many people know this product."

More Apache Web Server pros

"I think that the IIS includes most features that are required by web applications so that they can run smoothly on Windows operating system."

"The solution is very easy to use and offers a quick deployment."

"It helps scan and mitigates our vulnerabilities using the best protocols to secure our environment."

"My advice to others is this is a simple-to-use solution and you can find items with ease."

"The product is stable."

"Microsoft's technical support has always been very good."

"IIS fits properly for my business needs, with a lot of possibilities to upgrade the out-of-the-box functionalities, so it is really great."

"The solution is very stable, very simple, and easy to use."

More IIS pros

Cons

"Adding a reverse proxy to Apache Web Server would be a significant improvement."

"A monitoring interface would be great for this product. The monitoring dashboards for Apache's models are not included in the basic installation. You can install the basic monitoring model, then connect this model to another monitoring system."

"There is a security-related problem that depends on the web server's configuration."

"It would be great if technical support for Apache were available in Iran. It is a very important need."

"With Apache, you can't update the system. There is a big gap between models. I don't like this."

"I want the user interface to be more user-friendly."

"Its stability could be better."

"So far, for us, everything is okay."

More Apache Web Server cons

"The only disadvantage I see is that the documentation is a bit difficult to find."

"The visibility feature of the product is an area with certain shortcomings where improvements are required."

"Performance-wise, certain improvements in IIS are needed...IIS is not scalable. Its scalability is less."

"If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal."

"Scalability issues: No issues encountered but always go for two machines as one isn't enough and isn't fault redundant."

"If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal. I think there are cases where people need to use Apache instead of IIS when IIS doesn't work well with other web languages."

"The price of the cloud system is a bit high."

"The first level of support is not very good because by the time we speak with them, we are already past that point."

More IIS cons

Pricing and Cost Advice

"The apache software is free, open-source."

"It is a free-of-cost solution."

"There is no licensing cost for the product."

"It is an open-source solution."

"The tool is included with Windows."

"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."

"The price of Windows Server IIS is expensive. They have a large user base, and they charge a little bit too much."

"IIS is expensive."

"Users can get a subscription-based license or a perpetual license for IIS."

"I think it's part of the Windows Server, so you won't have any other costs to add in order to use the IIS service."

"There is a license needed for the solution."

"I give the price of the solution a five out of ten."

Overview

The Apache HTTP Server Project was founded in 1995 by a group of webmasters, known as The Apache Group, with the aim of developing robust, richly-featured, freely-available and commercial-standard Web (HTTP) server source code. The result was Apache Web Server or Apache HTTP Server, which is an open-source public-domain web server.

This collaborative project has been enhanced ever since with contributions from the core development team and other volunteers situated all over the globe. Also, hundreds of users of this open-source web server have contributed code, ideas, and documentation. The project falls under The Apache Software Foundation, which manages many open-source projects.

Apache

Internet Information Services (IIS) provides a secure, easy-to-manage, modular and extensible platform for reliably hosting websites, services and applications. With IIS, you get choice and control without giving up reliability or security.
