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.
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.
