Study Notes
Web Application Architecture
- Web application architecture refers to the structure and organization of a web application system, defining the relationship between different components.
- It enables the definition of functionality and logic between the server and client side.
Need for Web Application Architecture
- As web applications become increasingly complex, a well-defined architecture is crucial.
- It addresses increasing complexity and demands of modern web applications, providing a structured approach to design, develop, and maintain web applications.
- Benefits include scalability, manageability, maintainability, reusability, and enhanced performance and security.
Benefits of Web Application Architecture
- Scalability: enables accommodation of increasing user traffic and concurrent user demands through horizontal scaling.
Types of Web Application Architecture
- Monolithic Architecture: a traditional approach where the entire application is built as a single unit.
- Microservices Architecture: a modular approach where the application is divided into smaller, independent services.
- Serverless Architecture: applications built using serverless functions or "Functions as a Service" (FaaS) platforms.
Monolithic Architecture
- Characteristics:
- Single Codebase: the entire application is written and maintained within a single code repository.
- Centralised Database: all data access and storage functions are handled by a centralised database shared across the application.
- Tight Coupling: components are interconnected, making it challenging to modify or replace individual elements without affecting the entire application.
- Workflow: developers work on different parts of the application within the same codebase.
- Pros: simplicity; cons: scalability issues.
Layers of Modern Web Application Architecture
- User Interface (UI) Layer: handles presentation and user interaction using HTML, CSS, and JavaScript frameworks.
- Application Layer: implements business logic, validation, and data processing.
- Data Layer: manages storage and retrieval of data, often through relational or NoSQL databases.
- Infrastructure Layer: includes servers, networking, and other components required to host and deploy the application.
User Interface Layer
- Responsible for rendering the user interface and managing user interactions.
- Utilizes HTML, CSS, and JavaScript frameworks to create responsive and engaging UIs.
- Enables client-side interactivity, AJAX requests, and handling events.
Application Layer
- Implements the core logic of the web application.
- Handles user requests, performs data processing, and communicates with the data layer.
- Can be built using server-side frameworks, microservices, or serverless functions.
Data Layer
- Manages the storage, retrieval, and manipulation of data.
- Includes databases, such as relational databases or NoSQL solutions.
- Involves techniques like data modeling, querying, and caching.
Infrastructure Layer
- Provides the necessary infrastructure for hosting and deploying the web application.
- Involves servers, cloud services, load balancers, and networking components.
- May use technologies like containers, virtual machines, or serverless platforms.
