Express.js, or simply Express, is a back end web application framework for building RESTful APIs with Node.js, released as free and open-source software under the MIT License. It is designed for building web applications and APIs. [2] It has been called the de facto standard server framework for Node.js. [3]
A downside of this single-threaded approach is that Node.js does not allow vertical scaling by increasing the number of CPU cores of the machine it is running on without using an additional module, such as cluster, [55] StrongLoop Process Manager, [56] or pm2. [57] However, developers can increase the default number of threads in the libuv ...
The CGI script passes its output, usually in the form of HTML, to the Web server, and the server relays it back to the browser as its response to the browser's request. [ 2 ] Developed in the early 1990s, CGI was the earliest common method available that allowed a web page to be interactive.
For a typical web application, the application server sits behind the web servers. An application server framework is a service layer model. It includes software components available to a software developer through an application programming interface. An application server may have features such as clustering, fail-over, and load-balancing.

FastCGI is a binary protocol for interfacing interactive programs with a web server.It is a variation on the earlier Common Gateway Interface (CGI). FastCGI's main aim is to reduce the overhead related to interfacing between web server and CGI programs, allowing a server to handle more web page requests per unit of time.
The Java EE deployment descriptors are defined by the language specification, [2] whereas the runtime descriptors are defined by the vendor of each container implementation. For example, the web.xml file is a standard Java EE deployment descriptor, specified in the Java Servlet specification, but the sun-web.xml file contains configuration data ...
The Java Module System does not intend to support all the functionalities that the OSGi platform currently supports (for example the Life-Cycle model and the Services Registry). However the Java Module System will support functions which are not supported by OSGi, such as modularity at compile-time, and built-in support for native libraries. [ 15 ]
