WEB APPLICATION ARCHITECTURE?
WHAT IS WEB APPLICATION ARCHITECTURE?
•
A Web application is a complex piece of software. It consists of many components like the user
interface, a login-screen, an in-app store, the database, etc. To manage these components,
software engineers devised web application architecture to logically define the relationships and
manner of interactions between all of these components for a Web app.
•
Basically, web application architecture is a framework (or some people might call it a mechanism)
that states its main external and internal components, the relationship and interaction between
those application components (middleware system, user interfaces, and databases).
•
Its primary mission is to make sure that all components work simultaneously and be a strong base
to build and set up everything afterward.
•
Every Web application consists of both a front-end and a back-end.
•
The front-end, also known as the client-side, is everything that the user sees and interacts within
inside their browser. The main purpose of the client-side is to collect data from users. It is written
in variants of HTML, CSS, and JavaScript.
•
Next, we have the back-end, also known as the server-side of the app. It is the part, which is not
accessible by users; it stores and manipulates data. The backend processes HTTP requests which
essentially “fetch” the data (text, images, files, etc.) called for by the user. Unlike the frontend,
many languages like PHP, Java, Python, JavaScript, and others can be used to write the backend of
a Web Application.
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.
