Centralized versus decentralized application architecture

We have compared DLTs and databases by analyzing their properties. But it's also important to analyze the architecture of the application before implementation. We will describe the architecture for both centralized and decentralized applications so that there will be more clarity about the components and the way in which they communicate with each other.

In an application that uses a basic centralized server architecture, there will only be a single instance of all the components involved. Figure 11.4 shows the architecture diagram of a web server application. The user can communicate with the web server through the user interface provided by the web application. A web application ...
