Web system Architecture

A Web system architecture is the underlying design and organization of a web-based system, including the technologies, protocols, and components that enable its functionality. The architecture of a web system determines how the different components interact with each other, how data is transmitted, and how the user interface is presented.

Key Components of Web System Architecture:

• Client-Side Components:

These are the components that run on the client-side, which is typically the user’s computer or device. Client-side components include web browsers, scripting languages, and user interface components such as buttons and menus.

• Server-Side Components:

These are the components that run on the server-side, which is typically a remote server or cloud-based system. Server-side components include web servers, application servers, and databases.

• Communication Protocols:

These are the protocols that govern how data is transmitted between the client-side and server-side components. The most common communication protocols used in web system architecture include HTTP, HTTPS, and WebSockets.

• Data Formats:

These are the formats used to represent and transmit data between the client-side and server-side components. Common data formats used in web system architecture include JSON, XML, and CSV.

• APIs:

APIs, or Application Programming Interfaces, are the interfaces that enable communication and data exchange between different components of the web system. APIs provide a standardized way for applications and services to interact with each other.

• Security:

Web system architecture must also include security mechanisms to protect against threats such as hacking, data breaches, and other cyber attacks. Security mechanisms can include encryption, authentication, and access control.

Types of Web System Architecture:

• Client-Server Architecture:

This is the most common type of web system architecture, where the client-side and server-side components are separate entities. The client-side component typically consists of a web browser, while the server-side component includes a web server, application server, and database.

• Single-Page Applications (SPA):

This type of web system architecture is designed to provide a more responsive user interface, where the user interface is loaded once and then updated dynamically without requiring a full page refresh. SPA is typically implemented using JavaScript frameworks such as React and Angular.

• Microservices Architecture:

This architecture is designed to break down a large, monolithic application into smaller, independent services that can be developed and deployed separately. Each microservice is responsible for a specific function or feature, and communication between services is typically done using APIs.

• Progressive Web Apps (PWA):

PWAs are web applications that are designed to provide a native app-like experience on mobile devices. PWAs use a combination of web technologies such as HTML, CSS, and JavaScript, along with features such as offline caching and push notifications.
