Microsoft IIS features and specs

Integration with Windows Server
Since IIS is developed by Microsoft, it offers seamless integration with Windows Server, leveraging features like Active Directory, .NET Framework, and PowerShell for enhanced performance and manageability.
User-Friendly Interface
IIS features a graphical user interface (GUI) that simplifies the server setup and management process, making it easier for administrators to configure and maintain web applications.
Extensive Documentation and Support
Being a product from Microsoft, IIS offers comprehensive documentation, extensive online resources, and professional technical support, which can be highly beneficial for enterprise users.
Security Features
IIS includes various built-in security features, such as dynamic IP restrictions, request filtering, application pooling, and integration with Windows authentication, making it a secure choice for hosting web applications.
Performance and Scalability
IIS is optimized for performance and can effectively handle multiple requests and high-traffic websites. It also supports load balancing and server farms to enhance scalability.

Possible disadvantages of Microsoft IIS

Cost Considerations
Unlike some other web servers that are open-source and free, IIS may incur licensing costs as it requires a Windows Server license, making it potentially expensive for small-scale deployments.
Platform Dependency
IIS runs exclusively on the Windows platform, which can be a limitation for organizations that use a diverse set of operating systems or prefer open-source ecosystems like Linux.
Complex Configuration for Advanced Features
While IIS offers a user-friendly interface for basic setups, configuring advanced features may require considerable expertise and can become complex, particularly for those unfamiliar with Microsoft's environment.
Performance Overheads
IIS may introduce performance overhead due to the multiple layers of abstraction and integration with Windows features, which can affect performance in some high-demand scenarios compared to lightweight, minimalist web servers.
Lower Community Support
Open-source web servers like Apache and Nginx have large, active communities that contribute to continuous improvement and troubleshooting. IIS, being a proprietary product, has a smaller community in comparison.

OpenResty features and specs

High Performance
Built on NGINX, OpenResty benefits from high-performance HTTP server capabilities, capable of handling a large number of simultaneous connections efficiently.
Extensibility
Integrates seamlessly with the LuaJIT scripting language, allowing for powerful customizations and extending the server's functionality without the need to modify core code.
Rich Ecosystem
Supports a wide range of third-party modules for various functionalities such as caching, security, request manipulation, and more, fostering a comprehensive and versatile ecosystem.
Asynchronous Processing
Capable of non-blocking processing, which is essential for real-time web applications, ensuring lower latency and higher throughput.
Active Community and Support
Backed by an active community and commercial support options, providing ample resources for troubleshooting, enhancing functionality, and keeping up with the latest best practices.

Possible disadvantages of OpenResty

Steep Learning Curve
Requires proficiency in Lua scripting and understanding of NGINX configuration, which might be challenging for those new to these technologies.
Complex Debugging
Debugging Lua code within OpenResty can be complex, lacking some of the more advanced debugging tools available for other languages.
Limited Documentation
While there is documentation available, it may not be as comprehensive or beginner-friendly compared to other more mature web server ecosystems.
Niche Use Case
Primarily suited for high-performance applications requiring custom HTTP server behavior, which might not be necessary for simpler web applications or APIs.
Resource Intensive
Depending on the complexity of the Lua scripts and modules used, OpenResty can become resource-intensive, requiring careful optimization and resource management.

Apache, IIS, NGINX, GWS : What’s Your Choice?

Utilizing a specific type of virtual or physical server determines the type of web server software you use. If you prefer Microsoft, then you will prefer to use IIS (Internet Information Services / Server) by Microsoft as your primary web server application solution. If you use Linux distribution, you have other alternatives like Apache, NGINX and LiteSpeed.

What Is the Most Popular Web Server Application in 2021?

Despite being bundled with most modern Microsoft software, IIS loses out to Apache on its own devices. The main selling point here is performance. While IIS has kept up with Apache in recent times, Apache has historically been performing much better, which still gives it an edge over IIS.

Scriptable Operating Systems with Lua [pdf]
It's maybe deprecated by the official Nginx support, but there are other projects and organizations that are offering Lua scripting with Nginx with all kinds of extensions and libraries. See OpenResty website[0] and Github repo[1]. [0] - https://openresty.org/en/. - Source: Hacker News / about 1 year ago
Ask HN: The C10M Problem
Have you seen https://openresty.org/en/ before? To share a quote directly taken from their website: > By taking advantage of various well-designed Nginx modules (most of which are developed by the OpenResty team themselves), OpenResty® effectively turns the nginx server into a powerful web app server, in which the web developers can use the Lua programming language to script various existing nginx C modules and... - Source: Hacker News / about 1 year ago
Show HN: Lockbox: forward proxy for making third party API calls
Nginx is quite extendable, there are tons of nginx plugins to help you add more customizations. There is OpenResty, a version of nginx [0]. It allows you to script all sorts of stuff with Lua inside nginx itself. Tools like lockbox are not necessary, nginx, caddy, etc or heck even a normal 70 line python3 fastapi based script works just fine and should be more extendable than lockbox.

Five Apache projects you probably didn't know about
APISIX is an API Gateway. It builds upon OpenResty, a Lua layer built on top of the famous nginx reverse-proxy. APISIX adds abstractions to the mix, e.g., Route, Service, Upstream, and offers a plugin-based architecture. - Source: dev.to / over 1 year ago
Apache APISIX plugin priority, a leaky abstraction?
Apache APISIX is an API Gateway, which builds upon the OpenResty reverse-proxy to offer a plugin-based architecture. The main benefit of such an architecture is that it brings structure to the configuration of routes. It's a help at scale, when managing hundreds or thousands of routes. - Source: dev.to / over 1 year ago
