Layered Architecture organizes software into distinct tiers, each handling specific responsibilities like presentation, business logic, and data storage․ This modular approach enhances scalability, maintainability, and reusability by separating concerns․ Each tier communicates with adjacent layers, reducing complexity and enabling easier updates․ Widely used in enterprise systems, it ensures a clear structure for large-scale applications, promoting organization and efficiency in development and operations․
Monolithic Architecture
Monolithic Architecture is a unified, self-contained structure where all components of an application are built as a single, indivisible unit․ This approach simplifies development and deployment for small-scale projects, as everything is tightly integrated․ However, it can lead to scalability issues, tight coupling of components, and challenges in maintaining or updating specific parts without affecting the entire system․ While it offers simplicity initially, it becomes less flexible as the application grows or requires modular enhancements․
Microservices Architecture
Microservices Architecture breaks down an application into loosely coupled, independent services that communicate via lightweight protocols․ Each service is responsible for a specific task, enabling modular development, deployment, and scaling․ This pattern enhances scalability, flexibility, and fault isolation, as failures in one service dont affect others․ It supports diverse technologies and is ideal for large, complex systems requiring frequent updates․ However, managing communication between services and ensuring operational consistency can introduce complexity․
Event-Driven Architecture
Event-Driven Architecture (EDA) revolves around producing, processing, and reacting to events․ It decouples components, enabling asynchronous communication and scalability․ This pattern is ideal for real-time systems, as it allows immediate responses to events․ EDA supports fault tolerance and enhances system flexibility․ However, managing event flows and ensuring data consistency can be challenging․ Modern applications leverage EDA for its ability to handle high throughput and provide responsive user experiences, making it a cornerstone of contemporary software design․
Model-View-Controller (MVC) Pattern
The Model-View-Controller (MVC) pattern is a widely used architectural approach that separates an application into three interconnected components․ The Model manages data and business logic, the View handles user interface, and the Controller mediates between them, processing inputs and updating the Model or View․ This separation enhances maintainability, scalability, and team collaboration, allowing developers to work on different parts independently․ MVC is particularly effective for web applications, promoting a clean and organized code structure that simplifies development and future updates․
