Pros and Cons of Web Servers, Node JS Web Server, Apache Tomcat Server and Nginx

What is a Web Server ?

A web server is software and hardware that uses HTTP (Hypertext Transfer Protocol) and other protocols to respond to client requests made over the World Wide Web(WWW). The main job of a web server is displaying website content over storing, processing and delivering webpages to users. Please refer the Pros and Cons of Web Servers in the below.

Node JS Web Server

Node.js provides capabilities to create your own web server which will handle HTTP requests asynchronously.

You can use Nginx or Tomcat or any popular server to run Node.js web application but it is recommended to use Node.js web server.


  • Node.js offers an Easy Scalability
  • Offering High Performance
  • used as a Single Programming Language (JavaScript)
  • Support of Large and Active Community
  • Handles the Requests Simultaneously
  • Node.js is Highly Extensible


  • Reduces performance when handling Heavy Computing Tasks
  • Node.js invites a lot of code changes due to Unstable API
  • Node.js Asynchronous Programming Model makes it difficult to maintain code
  • Choose Wisely – Lack of Library Support can Endanger your Code
  • High demand with a few Experienced Node.js Developers

Apache Tomcat Server

Apache Tomcat, one of the most popular web server and so popular for Java developers. Tomcat is a platform-independent tool, and, as long there is Java installed, the installation is a straightforward process. You just need to download the desired version from the official website and then unpack it on your file system.


  • Incredibly Lightweight server
  • Open-Source
  • Highly Flexible
  • Server Will Be More Stable
  • Offers An Extra Level Of Security
  • well-documented
  • widely used Java application server
  • Geared towards Java-based content


  • Tomcat might not be as fast as Apache when it comes to static analysis
  • The memory leak is one of the weak spots of Tomcat
  • You might encounter some complications in SSL installation with Tomcat
  • Tomcat’s user interface is primary and not as high quality as it should be

Nginx Web Server

Nginx is a simple, lightweight and fast web server. It is specially designed for high traffic websites. Nginx was designed from the ground up to use an asynchronous, non-blocking, event-driven connection handling algorithm.

The main difference between Apache and NGINX lies in their design architecture. Apache uses a process-driven approach and creates a new thread for each request. Whereas NGINX uses an event-driven architecture to handle multiple requests within one thread.


  • Uses Non-blocking, Event-driven architecture that requires less CPU and memory.
  • It has a lot of options to optimize and serve static content. So serving the static content 2.5 times faster than Apache and consumes less memory.
  • Works great with a multi-processor environment.
  • Built-in configuration option to prevent DDoS attacks.


  • Can not process dynamic content natively.
  • Less extensive list of modules.
  • Supports Linux and Unix operating systems – Windows support is limited.
  • NGINX does not support something like the Apache’s .htaccess file.
  • Lack of log monitoring tools – Simply writes logs to files that you have to manually navigate.
