WEB APPLICATION ARCHITECTURE•Web application architecture describes the relationships between databases, servers, and applications in a system. It determines how the functionality and logic of a system are distributed between server-side and client-side. Basically, architecture is responsible for fitting together all the application elements: what your users see and interact with, and how the software handles operations on the internal level.•A modern web application architecture is based on the same fundamental structural components. •UI/UX components: these components aren’t incorporated in the underlying architecture of the web app. In today’s guide to web architecture, we will only touch briefly on UI/UX. Generally, these components are responsible for presenting a visual layout for the web application. They are connected to apps’ functionality but don’t interact with architecture. •Client component: it’s synonymous with the client-side. It’s written and run entirely in the user’s browser. This component doesn’t depend on the operating system or hardware characteristics. The main task of the client component is to ensure smooth interactions with clients. •Server component: this part of the application handles the internal logic and connects the functionality of the database. Here, all the user data is stored and managed. Developers use general-purpose languages to build server-side of the web application, such as PHP, Python, Java.
